yea maybe later .. still learning and did`t want to many plants or monsters as I do have limited space and do have em in my living room (you know smell and stuff .. sumthing I realy have to look in to in flowering I guess)

but I actualy do have a HPS (600W 2100K/92K Lumen I belive)

found a used one with brand new bulp and hangers and all for like 120$ but I will safe that for flowering .. maybe late flowering ? like last 4 weeks or so and then get a few more 2700K T5 bulbs to start flowering with (mostly to save electricity dunno yet ?)

here is my set up so fare

but once I have learnd more and know how big my plants get and how much room I actualy have and how much heat get a isue (summer comming) and all that I might go with 4 plants ..

have been thinking of going with 4 autos in a DWG tube under the T5 (would also solv the "all dark at night time" problem I might get with them girls I have now .. might have to use my badroom for dark time :) )

it would solv many thing I think .. tho I'm sure others will occur .. but might suit me and my grow room better ? lets see I will take it slow and do it right ..

Ooh yea and plants allready look better to day (foile sprayd them morning and evening yesterday with 1/2 strenges nuts)

will post some pictures later have to runn now ..

You're definitely gonna want to use that 600w HPS for flowering. T5s are good for veg, but that light won't reach the flowers unless you grow a SOG.

You can build your own tent with black and white poly and 2x2s. It's really easy and it allows you to design where and how you want to. From size to openings. I can post some pics of mine if you want to see them, but you can just google DIY grow tents for ideas if you want.

This is your first grow? Didn't realize, I think you're doing better than I did with my first plants. Lol.

lol yea .. fist grow .. atlest indoor .. done a few with a friend like 10-12 years ago ..

but a "normal" hamp strain and not so advanges as indoor growing .. more like .. make seed spur .. drop it in the ground and water and wait :)

did still grow some nice "trees" like 6-7 feet that gave like ½ a pound each .. but I bet THC level was like 5-10% and canabinol like 0,sumthing as you sumtimes had to feel and search for the effect .. tho ther was a effect .. you did`t have a need to smoke ;)

and the oil made from em was nice :) mix a few drops in the nicer tops and voila :)

about grow tent .. sure I would like one .. but ya know .. money and time .. mostly money tho :)

but also since I got the light .. ordered the seeds and was on the way while I was hanging rails and covers up in the corner of my living room :)

so agin maybe for next grow .. have to take it a step at the time ..

also .. relized that you have to keep it simple .. need to get the hang of it and then move on and add more stuff and learn on the way ..

cant rush in to this and add a lot of stuff Im not 100% sure how to use correctly ..

but my room is`t that bad actualy .. have a big living room L-shaped and like 120 sq. feet

use the fare corner (had to move a bookshell to the hall but its ok)

have rails in the sealing .. used 2 tick bed linnen .. one black one with as cover ..with inside and black out side just like a inch open (to let air out)

the plants is on a desk (4x2½ feet) room is like 5x3 .. under the table I have a intake with a tower fan puling air in ..
cover ends like a foot before the floor but lower then the table ..


building is new .. have nice air cirkulation .. I have no problem keeping temps. (72-78F) and humidity like 40-45%

only real problem is going to be smell and light .. (might need to use my bathroom to flower in :))

therfor Im thinking of autos for next grow so the littel light they might get in the fist 2 hours or so in the morning from out side wont hurt em ..

about the smell .. well been looking at a Bionaire BAP242S Hepa air cleaner .. cost like 100$ and can cover 30 Sq. feet .. might throw one in there and see it that is enough to live with

lets see ..

also why I only have 2 plants .. need to see .. wouldnt like to start 20 plants to discover that smell, heat and humidity would be sumthing I couldnt controle ..

less is more I guess ..

but realy considering a DWG grow next time .. Im sure I could fit 4 plants in under my 5 foot T5HO fixture and the soil would also be historie :) tho Im sure keeping PH and nutriens is atlest as hard in hydro ?

but the idea of auto flowering and dwg sounds nice to me fast growing small plants of high quality (if you can controle it Im sure)

Ooh btw

please post them pics .. always nice to get some inspiration ..


only problem and why I did`t go for a closed room was ventilation ..

cant realy make one with out cutting in the windows and have tubes running my sealing (dont like that idea .. atall)

or just makeing it vent. out in my room .. no real idea ther beside light proof maybe but then heat and air might be a problem ?

I could of course add a filter so it wouldnt smell .. thats might be a idea .. wont be hard to make the room I have now 99,9% light tight ..

so then I jsut need to buy a good vent and filter ..

any idea`s ?

and do you think temperature will become a problem with that 600w hps ?

intake air would be like 72-78F

with the cover a bit open and my big table fan pointet at it I could keep it on about 82-85F 2 feet away ..

just affraid that I cant keep it if I seal it up ?

and some pictures


the plant I repot and gave some nutriens look so much better to day ..

DSC00415.jpg


did also go shopping a littel to day (in our walmart so to speak)

couldn't stop myself after I saw the result ...

so I found 2 big pots .. on sale .. one broken (so half price .. lucky me as allways its seems .. must be the green elf or sumthing :))

26L and 40 ccm wide (thats like 7 gallon and 16 inches wide) that MUST be enough to the end ..

DSC00420.jpg


and the one that was broke I used to repot the other one right away :)

roots sticking to the sides of the old pot and allmost as crowed as the small was .. so agin just in time it seems ..

DSC00418.jpg


so now they boath have room and I got the other 26L for the "small" one I can repot like 1-2 weeks before flowering ..

also here is a pic of my room .. tell me what you think

DSC00413.jpg


got a tower fan laying down under the table blowing air in under the table .. it pass up behind the table and wall so air flow is pretty good ..

Wow man, those plants look great! I was about to tell you that starting a DWG doing hydro would probably complicate things more for you since you said you were basically trying to keep it simple, but I think that you'd have things under control either way.

Actually, the reason I suggested a DIY tent is because you can build a nice little 6x3 or 5x3 for less than 30 bucks, and you could through that light mover in there and fit either 6 bushy plants in there and get 4-8 oz per plant or 15 and keep each plant in a sq ft. I prefer keeping them in an 18" space because it makes watering easier and keeps my count down.

Didn't you say up there somewhere you were vegging in a 5x3 area of your living room? You could just poly off the opening it'd be super efficient. I'll take a pic of the 4.5x4.5 tent I just did where I only had to tent one opening and post it tonight, but I've got these for now.

Sorry I don't have any more "instructional" looking pics lol, they were all phone pics I took real quick. I'm building a 3.5x4 tent in a corner of my veg room sometime this week, so I'll make a DIY post and I'll let you know when it's up.

And if you think you wanna build one I can price it out for you tonight when I get back on here. You could have a ventilated tent with fans and oder control for less than $200 for sure.

But you seem like a pretty "everything in it's right place" kinda guy and that's how I am, so you'll probably feel like a setup like this would make things easier and more efficient for you.

wow cool plants :)

and nice room by the look at it .. cant wait to see more and what you come up with .. keep em postet ;)


and yea my plants is`t looking bad at all .. specialy not to day :)

tell me what you think please .. still need sumthing ?

DSC00433.jpg



and yea .. I am a "right place" guy .. pretty logic thinking person (boath good and bad sumtimes)

I work as a stanless steel smet .. makeing machines for the medical and textile industrie ..

so could easily put sumthing together .. have been thinking of makeing a steel frame (1x1 inch stanless steel) and put up some wood on the side and top .. and make holes for vent. aso


can also fist perforatet stanless steel plate in the bottom to set the plants on and for a air intake (so the air pulld in comes up all over around the plants .. if that make any sense ?)

but you know .. Rome was`t build in one day ..
and even tho this is funn and a nice hobby .. it do allready take up a lot of time .. have other stuff I also need to do ya know ;)

so over time I will upgrade .. now I atlest have nice lights some vent... pots (of right size) and more experiance ..

just need to take it slow and add stuff as I get use to growing .. but yea a light/smell seald room is on top of my list now ..

I guess on my 3th grow it could be up running ..

reason why DWG sounds good to me is mostly that I want to grow autos as they are fast and suit my set up/me (T5 .. small room .. night light wont be a problem and I can just keep em on 20/4 or 18/6 all the time if I want aso. seems more easy and I bet .. if you do it right you could get as much out of it as a nub grower or just someone who don't have optimal conditions and you harverst more often .. DWG will make it more optimal and I wont have to "fight" with dirt aso.)

btw

Im beginning to look at it this way ..

find out your needs and what you have to work with and then try to match it with a grow that will cover it ..

I dont have a spare room (or I would problerbly have got one more 600W HPS and made a all out stavia grow with like 8-12 big plants with a veg and a flower room and a big filter/vent aso. .. could most likely make enough for boath myself and a few cloose friends and let them pay for the room ;))

and I don't have limited money (or I would most likely just buy my smoke even tho it is a funn hoppy to grow)

so I have to do with like 3 sq meters (9 sq feet or so) and I have to do it a littel at the time .. might not be that bad as I can imagen you could make some bad buys if you do em as a nub ..

my needs as I dont sell or want to .. is just to cover my own needs ...

so I safe some money and dont have to put em in the rocker (HA/bandidos) pockets ..
and so I dont have to go trough the trouble of getting it and buying it and all what follows with that ..

and to have a funn hoppy of course ..



reccon I would like to grow 2 grams a day (if you could put it that way ?) 700 grams a year ..

that would cover my need plenty with enough to go around .. for weekends and friends aso.

so if I could haverst evry 12 week or so with autos I would just have to haverst like 160 grams (1/3 pound) so thats like 40 grams per plant if I have 4 :)

think that is possible with autos in DWG or any grow in my kind of room size ?

I average about 350-400 grams a meter...so I could do that 5 times a year in my flowering room.

So to be honest, if you only need 2lbs or less a year for personal...you can grow however the fuck you want lmao.

And the main reason for a tent is for more light reflectivity for better yields and to better control pest and oder, but if you don't need to grow much, that's not a priority for you either. So now I think I'm following what you're saying. ;-)

I'd say they can still probably take a little more N, unless it's just the flash from your camera making it look a little lighter green at the new growth, they still look great though. How tall are they now? They look at least 10-12" right? You're going to want to flip them to 12/12 by the weekend probably if you don't want them to be bigger than 2', and even at 2' you'll probably want to run that 600w HPS or you'll honestly just be upset with your yield..even if you're not real concerned with yield.

A few things I'm confused about though if you're just growing for your personal....why not grow organic? It's not really any more expensive than hydroponic nutes and the smoke is better for you.

Also, you'd be able to juice or eat your own fan leaves instead. Not sure if you've ever seen or read anything, but it appears that it prevents just about if not EVERY type of cancer from ever invading your body, prevents the onset of diabetes, prevents Alzheimer's, and promotes healthy brain function. I've been less anxious since I started juicing my fan leaves as well. General Hydroponics has a good organic line if you ever decide to give it a try, and they have a little trial size kinda setup with their whole line-up for cheap that'd prolly get you through a whole cycle. Done preaching, sorry lol.

Oh, and have you used any kinds of concentrates like ice-water hash, hash oil, tinctures, butters...you'll want to plan for more than 2 grams a day if you wanna benefit from growing your own as much as possible. I mean, I get it, some people just like to smoke and don't care about all the other stuff lol, but it just seems to me like if you're already going through all the trouble to grow it yourself, why not reap all the benefits right?

Oh, and one more thing....if it's just your personal smoke don't you want to be able to grow 2 or 3 strains you actually like instead of autoflowers? Autoflowers kinda suck IMO, and it seems like mostly newbs or people who just juice leaves grow them. They are literally ragweed. And the plants you've been posting look better than most of the pics I see from so-called professional growers. In fact, I'm over here giving you advice and I've got some purpling in my stems right now on my veg plants lol. :wall: So I wouldn't recommend autoflowers for you, not if you really want to be high. But like I said, you could literally just flower clones as soon as they are rooted under your CFL. And if you do as good a job on your flowering plants as you are on your veg plants, your buds are probably going to get you higher than you've ever been. :bigjoint:

ok lemesee ..

fist .. 350 - 400 g .. nice .. of course I want more :) but if I can grow enough to smoke a gram or two a day (maybe 3-4 doing weekends aso) Im happy .. but if I grew more I would proberbly make hash as you suggestet or more likely kif ..



just a snap shot ;)


DSC00421.jpg

this is what I "normal" smoke/buy .. either as this marrocan super hash or kashmir (same top quality)

cost like 100$ for 10g .. get me trough a week (but damn .. thats like +400$ a month)

btw
the bong head is my +20 years old mercum one (must have smoked kilos on it ;))


so wouldnt mind more (to make kif and maybe some oil .. done that many times before)

organic also sounds realy nice .. but as you know .. Im new .. one thing at the time .. need to learn .. can take it all in, in one day :D
but do sounds realy nice that

"ust about if not EVERY type of cancer from ever invading your body, prevents the onset of diabetes, prevents Alzheimer's, and promotes healthy brain function"


would like it all tho the "healthy brain function" might be to late ?


about tent .. still playing with ideas .. will most likely put sumthing together and keep upgrading ..

reflectivity for better yields .. well do I need it so much right now .. with my light for 2 plants (28K lumen T5HO/92K Lumen 600W HPS)
most of my room is white/yellow or have maylor .. will get more maylor though .. would like to cover the wall/coner with it ..

pest and oder .. well my appartement is realy well ventilatet (no real need to open windows .. tho summer time now .. so I will have one open .. also for fresh air flow .. so the window closed to my room (2M away) is mostly open now .. have it coverd with mosquito net) and I keep my appartement fairly clean (specialy the grow room .. also why I like to keep it simple)

but the oder might become a problem .. not that I realy have anything to hide .. all my friends and family know Im a smoker (most friends do it them self of course ;))

and my neighbors is realy cool ..

so it is mostly for my self and visitors .. so wa actualy can be in the appartment :)



and yea them new tops is a bit light green .. one plant more then the other .. will give them a bit stronger nutriens next watering ..

btw
how often should I folie spray them ? (I use like 1/4 strenges nutriens and yucca as you know ..

and yea 10-12" is about right ... maybe 15" but one is bend a bit (just startet to lst a bit agin) and other one is Fim/LST





and yea I would like more strains .. this was just the fist I choose as it is small and I could get the seeds in my local store (5 femi for 40$)
would like to try out some white strains and maybe runn 2-4 diffrent at the time .. this was just a "quick start" if you know what I mean ..

couldt wait and had the light and most importent stuff .. so got the seeds/nutriens (floraduo) and dirt and PH test and was on the way ..
fist now Im begining to get a more clear pictur or it all and what I want .. but I guess I have to try out a few things for myself .. about autos .. well just sounded like my kind of grow .. small .. fast .. good quality and a bit more easy with light aso. but dunno yet .. will consider it more and choose sumthing when my 2 ladys is in to flowering so I can be ready to start some new once .. either 4 autos or maybe another dirt with 2 more of them ladys and maybe 2 more of some with strain if I belive I can fit em all in ? maybe build the room so its done in time for them to flower ?

lets see ..


Ooh yea and thanks for the kind words .. tho my stems is purple as well :)) is that bad ?
back when I grew out side them plants who was purpleing was mostly the best/strongest once ?

p.s

so fare (in the old pots) I have been watering evry 3-4 day or so ..

but new pots are way bigger .. did of course give em a good runn of water when I repot em ..
can feel now that the smaller one (the fist I repot ..in a 3½ gallon pot 5 days ago) is getting light ..

but the dirt still feels a bit moist like a inch down ..

any suggestions ? dont want to over water .. but Im thinking in the morning with ½ insted of 1/4 strengs nuts ..

btw
hot spring days here 25c/78F so grow room is like 80F and 45% humidity at mid day .. so I bet they do use some water ..

Well if you decide to go organic in the future, PM me if we're not still shooting the shit on this thread, I'll make it easy on ya ;-)

Actually, eating or taking things that support healthy brain function will help you at any time in your life, despite age. Since I started juicing leaves I have less anxiety, less RAGE, guilt, and depression, my attention span is better (even after smoking lol...most strains at least;-)), I'm more alert, etc. I also started juicing lots of other fresh veggies and greens though...so maybe I'm cheating? lol. I even started juicing spinach, it apparently has a natural steroid in it. Popeye was on to something. Lol.

pest and oder .. well my appartement is realy well ventilatet (no real need to open windows .. tho summer time now .. so I will have one open .. also for fresh air flow .. so the window closed to my room (2M away) is mostly open now .. have it coverd with mosquito net) and I keep my appartement fairly clean (specialy the grow room .. also why I like to keep it simple)

Of, if you're in an apartment, you ABSOLUTELY have to worry about odor control. It's not gonna smell like you're smoking or holding in there...it's gonna smell like you're a fucking skunk serial killer. Seriously. When I first started growing my dad, who's been smoking most his life, came over and was complaining about skunks in the neighborhood lol. I had 6 plants in a room in the garage, and it smelled a block away.

So even if your neighbor is cool, people are gonna be smelling it down the street probably. And the odor just keeps producing and producing, even with just a couple plants.

So here's the deal...if you're at 12-15 inches...and you don't want them to be monsters..you've gottat flip them to 12/12 and then almost double up on your nutes with the next watering after they're flipped, because they are going to at least double in size over the first 2 weeks of 12/12.

You're gonna wanna put em under that 600w reflector. And you're going to want to build some sort of tent so that you can ventilate and filter the odor. If you go to the Grow room and design forum on this site, there's a dude named Phillipchristian that designs grow rooms for people for free with auto cad and shit like that. Since you said you fabricate metal or whatever, you may want to talk to him and work out something fancy....but if you want something cheap simple and effective, like I said, I can help instruct you on how to set up a tent in just a few hours for around $200.

But you've got 2 weeks after you flip to 12/12 before oder will start to become a problem, so you can flip them now and you've got time to do the tent if you're busy this week or whatever. Also, getting this done within two weeks is going to give you that reflectivity anyways, so it will increase your yield from this first harvest. And if this is the only harvest you're going to get for the next couple months, you wanna get at least 4 oz off of each plant right?

Hey no prob man. Yea, the purple in the stems is usually deficiency. And usually N unless there are other obvious problems. But you already knew you needed to up the strength of your nutes a little, but now you'll probably want to double them if not just about when you flip.

Some of the "purple" strains have purple in the leaves, calyxes, and stems, but only later in flower, not in veg.

When using bigger pots, the soil is usually going to dry out on the top few inches before the rest of the pot, so just keep lifting up the pot a tiny bit untill you feel like it's almost dry and then remember what that felt like. I flower in 5 gal pots with 30" Indicas, which is probably how tall yours will be in a few weeks, and I water every 3-4 days most through most of flowering. Some more aggressive feeders get watered every 2-3 days later in flower.

ahh ok thanks ..

it do feel realy ligh compaird to when I fist water it .. so I guess I wont ruin/hurt it if I water it tomorrow morning (6 days after I repot it and "flodded" the pot) would like to give it some N


my plan was to wait like 2-3 weeks more before going in to 12/12 .. dunno .. but I do have space and light and big pots (7 gal.)

also since I did FIM/LST them ..

so was planing on sumthing like 8 weeks from seed (2-3 weeks from now)

would also give me a week or 2 (after pay check) to design something .. and buy some more 2700K tubes (want to start flowering with t5 and have em ready for hot days .. will use 600W HPS on cooler days or end of days and most likely last 4 weeks is possible .. summer now .. next grow will be more easy with temp.)



so they will realy smell that much ?

I guess it become a lot wors then .. now I can just smell em when entering the appartment .. nothing more .. after 2 minuts I dont smell em .. but I guess I have to look in to sumthing fast then ..

been looking at some cheap bathroom ventilation exhaust 100m (4 inch) do 120M2 a hour so if room is 12M2 (witch it wont be .. maybe half)

it changes air in 6 minuts .. same store (close to me) also got activ carbon. filter mats can get the vent for like 12$ and mat for like 25$

you think that is enough ?

if I make some kind of box .. with the vent out and carbon filter behind and the place it on top of the room I make ..
with a 4 inch hole and of course air tight .. so it takes air out trough the filter ..

can easily make it 2 ventilations as they cost so littel and the mat is big enough for 2 .. if needed ..




and I might look in to that organic a bit more .. Im sure I will .. just that I seems to have my hands full right now ..

a room is my first priority for sure ..

If you don't veg long you only need to feed once or maybe twice in veg...mj doesn't actually need as much nitrogen as people sometimes think....

k .. but I have`t reach full feed yet .. only 1/4 so fare and it realy seems like it need more so I will go ½ strenges ..

maybe do one full before switching ?

here are some pictures .. tell me what you think .. would it be enough ?

2804.jpg


3984.jpg


sumthing like that .. can get it all for like 30$ or so ..

would that be enough to vent 6x3 feet room ... 6-7 feet tall

and would it take care of the smell ?

note: I can easily buy and fit two of them vents if needed .. but is it good enough for that room size ?

if my math skills dont let me down .. it could take out the air of a room that size in like 3-4 minuts
 

+ WitchDoctor +

Well-Known Member
No, that won't be enough to vent a 6x3 room. And to be honest I'm not sure about the carbon, I think you'd be better off using a carbon filter meant for what your doing, as well as a fan. You need something like this. https://www.htgsupply.com/Product-A-GrowBright-4in-Inline-Fan-&-Carbon-Filter-Combo.asp With something like this you might still smell it in the hallway (probably not though), but not outside of the apartment.

And you can definitely let them go another couple weeks, just be ready for them to double in size. It literally happens before your eyes practically. You can always lollipop them before you flip and give them plenty of free room and a clean branch to make it easier to water and cut down on all the scraggly little buds that don't get light.

But as soon as you flip to 12/12 you've got a week or two to have that tent up. :blsmoke:

ahh ok .. no problem price is ok .. just have to find it in eurpoe (UK would work well) will search tomorrow ..

also got a nice idea for room ..

I can use the holes I allready made in the sealing for the rails .. to make a wood frame (well a half a wood frame) shaped to fit in the corner ..

then just add 3 vertical down to another frame and then just cover it in cheep masonit wood and maylor inside and make some hole in the top and bottom for that filter and a intake .. and use my double sheets for entrence with velcro ..

thanks a lot .. Ill post more tomorrow :)

plants just go nighty night so will I ..

Oh, my bad didn't realize your were UK. If I give US links in the future my bad lol, I'm forgetful. Mylar works great, but if you use it get ready to randomly get shot in the eye with reflected light lol. I use black and white poly with tent zippers, I'll post the links so you know what I'm talking about. https://www.htgsupply.com/Product-Tarp-Zip-Up.asp https://www.htgsupply.com/Product-10-Foot-by-10-Foot-sheet-of-Black-&-White-Poly---6-mil.asp

The velcro wouldn't work with the black and white though, but if you decide to use mylar you can use velcro with that for sure.
