i have enough led power to push 65 watts per square foot , hahaha, I know Tim allen effect, i am probably pushing 50 watts per right now with 6 cobs in my 2x3
I was thinking of doing basically the ability to do 50 watts per sqft in flower lol.. I have a 5 cob 250 watt rig (Cree CXB3590s at 3500k on a straight bar approx 12 inches apart at center) now I ran alongside my 600 watt hps and was going to get 4 more of those same cob kits and space them a foot apart. that would be 25 in a 5x5 lol then move my hps to a veg room and eventually convert that also when costs allow. I have been going back and forth between getting another Timber kit (SO easy and same as I got the first time) or ordering from Kingbrite on alibaba and dealing with putting everything together from scratch and shipping from China and all that... its about $169 difference (not counting the shipping cost from China which I have no idea of). I have heard that having more lights and running at lower power is actually more efficient for LEDs so i guess that is what I am going for. Also then in the future I have many modular cobs that can be used in many different growing applications if a newer tech comes along I want to but into. ....So yeah MORE POWER... oh wait... less power technically right?? hahahahaha

my sip is doing great, 64 days of veg since I got the cut, and now on 10th day of flower, she's covering a 4x4 area!

I always tought with organic soil the more soil space you have the better, since you increase your space for bacteria and fungi to live. Also more room for organic matter thats gonna feed your plant and of course for the roots also. People usually say you need at least 10gl of soil to see your plants true potential. Not sure how much soil your sip holds but it doesn't seem that big. Could you share your experiences about this topic because obiviously your plant is doing good in that small space.

From all that I have read I think that it is much EASIER to maintain a healthy bio micro herd in a larger mass of soil.... I have always been under the same impression as you that you need at LEAST 10 gal to really get the most benefits out of an organic and recycled soil system. I have seen folks on here doing it with smaller volumes though, but it seems much harder to maintain and also would seem like you would need to be a lot more attentive with teas and top dressing seeing that you will not have as much food and sugars in a smaller system for your micro herd. I have been playing around with the idea of a very large SIP that basically would cover most of my 5x5 flower area and act basically as a raised bed then I could do a sea of green with clones all in ones SIP.. the part I cant really get around is how to get to the back corner for pruning without A. a tom cruise mission impossible style harness(lolz) or putting the whole thing on a lazy susan so it could spin... but then you are into moving parts and all this and that is NOT what SIPs are all about. lol ... sorry rambling... there are my 2 pennys (-:

What if your tent was only 2x2? Like mine. I was thinking on building a SIP bed as big as my tents floor to grow a single big plant with diy scrog net on top. I got four 2' Samsung F series gen3. single row strips on the way as my new light. I'll upgrade it to 6 when I got the money, the driver I got is perfect for 6 of em(hlg-120h-c1050b).

My only concern is getting the wick dimensions right. And making the soil part removable from the water reservoir but also keep it sealed when they are connected.

If you guys could help me plan the build I'll be really happy.

I can't say exactly how much soil it holds but I can promise you its way more than 10g my guess would be somewhere around 20g.

here's my journal/experiment. check it out, it has all the answers about what and how I do this.

Oh okay thats cool then, I tought it was less than 10gl so thats why I was suprised with the growth.

I really don't want to build my sip with totes, those things are too expensive for their worth at where I live. So I wanna build the whole structure myself from ground up. I don't want to waste any space that could be holding soil.

I paid 7 bucks per tote, a 15g smart pot is like 10 bucks!

I'll check if I can find any totes that will fit in my space like I want it to. I'm still waiting for my first grow to finish. It's day 47 for oldest auto. Got around 40 more days so I'll figure something out. Thanks though.

That's what I kinda "engineered" for now. I call it "Gravity fed Wicking Sip" or "GFWS". I stuck a serum hose to bottom of the bottle, made little holes on the hose, broke a toothpick in half and stuck it to end of the hose so it could act like "wicking medium" and help keeping the hose straight while going in the soil.. Then stabbed the poor soil with long screwdriver, fed the hose through the hole it made. Closed the bottle so water won't evaporite but made couple of holes on the cap.

I made it with the stuff I had laying around but I'm thinking on buying a real bigger hose, filling the end of it with good bit of soil and making holes on the portion of the hose thats filled with soil (imitate the wicking net pot basically). I probably would secure end of the hose with some type of screen to make sure soil doesn't come out and cause water pouring out freely instead of wicking through the soil. Then maybe attach it to bigger reservoir and keep it outside of the tent. Run the hose through passive air intake hole.


Downsides: I won't have water roots.

Goodsides?: Much easier access to reservoir. Space saved by having the option to move your reservoir outside. You can wick as many pots as you want with a single reservoir by multiple hoses, so you multiple the saving space part. You can make your reservoir as big as you want, let that sink in for a second(Are you going to Bahamas for the summer? Get a big tank, stick the hose and you good to go. Are you going to jail for growing weed? No worries, stick the hose in and boom... Just like that, you got something to smoke when you come out. No need for building a pot from tote just stick the hose into whatever pot/bed you using. You can increase/decrase (add more holes or more hoses) and move the wicking area according to how wet you want your soil whenever you want.

I think I accidentaly found something useful. Hello my highschool teacher, what do you think about that.. huh?

I will build it tomorrow, probably will post pictures for better explaining but its basic stuff.

There is the techincal drawing for the system.
huh how did I miss these posts!? so this is gravity system that feeds DOWN? Won't that result over watering? I also have to agree with @Greenthumbs256 as far as cost of making SIPs. I actually have it broken down for what I paid for everything to make mine....

14 Gallon roughneck tote: 2 @ $6.00 = $12.00

5” net pot: 20 @ $16.00 (1per tote = $0.80)

Zip ties pack @ $5.00

1-1/4” pvc 8’ @ $2.00 (about $0.41 per 20 inches)

Screw nuts washers @ about $5.00

Landscaping fabric about $10.00

Grommet and elbow about $5.00

3/8” bit (have)

¾” precision bit $15.00

1 3/4” hole saw $11.00

3” hole saw $13.00

Jigsaw (optional) $60.00

$91.00 (buyng hole saws, precision bit & not including jig saw)


$24.00 for each next

Yes I very much would like to try something like this also! Let me know if you try it out or have design ideas I would love to see them!

I'd like to have a permanent sip box in my 4x4 tent. I think having a 3x3 bed in my 4x4 tent I could grow my four legal plants and that would be my best option. Until then I will be playing with my earth boxes and building some more tote sips for veggies in my back yard.

hmm sounds like others are interested in this also ... maybe I will have to start brainstorming...

I've been thinking about this for a couple years now. And I keep thinking if we can recreated nature in an indoor environment NASA can use it when we go to Mars. I'll make billions of dollars from it and freedom 35 is in right on track. haha easy street
