Made my money quicker than expected, so I killed my first plant and decided to set up the whole thing. No more half closet plans :joint:

Equipment
-2x 400w Lumateks
-2x 240CFM Booster Fans
-1x 440CFM Ventech Inline Fan & Filter Combo
-2x 400w Hortilux Super HPS Enhanced Spectrum Bulbs
-2x Xtrasun 6" Air-Cooled Reflectors
-1x 8-Bulb T5 With Both Bloom and Grow Spectrum Bulbs
-1x 9K BTU Haier A/C Unit

Closet should be completely set up and ready to grow tomorrow. Environmental control tests through Sunday. Germination scheduled for Monday (cause' my replacement timer isn't here yet). It'll be fully sealed so I can setup CO2 Supplementation when my money's back up.

All advice, criticism, etc. is welcome. If you have to be an asshole to get your point across then go ahead! I'll take anything as long as I learn and am able to perfect this grow.

Also, I'm planning to do 4 plants my first run. A 3'x2' SCROG (2"x2" holes) under each light. 2 plants each screen. Running the Pure Power Plant strain from Nirvana. What do you guys think I could expect as far as yield goes, assuming I have close to optimal conditions? I know there's many variables, but a ballpark number would be cool. I'd like 10-16 ounces.

if its your first grow id just stick some autos in 4-5in each closet at 2.5oz a plant ;)
dont see an intake though
yield scrog if your good 800g maybe closer to 400g on you first grow the PP

i have pics on here of running 5 plants in one rubbermaid container in a closet that size under a 400...point being factoring electricity and other costs its more cost efficient to run more than just two plants in each space. they must be trained properly but thats not too hard. also i grew in soil so idk if your method of choice leaves you with less space. honestly what i would do here is go ahead and grow out four plants 2 in each closet but then move them all into one closet for flowering, by this time you should know sex and can take 8 new clones about a week before flower into a clone chamber and then eventually put the best 4 into the vacant closet. this will give you the same harvest you originally would get while having no down time between flowerings also this is much more cost effective due to the fact that you no longer need the second hps just some flouros in the veg closet which will cut 20 from electric but i see you added one flouro which confuses me because i thought your closets were supposed to be identical through the grow..anyway, temps will be easier to maintain as well...just all around better use of the space imo...and to guess yield i must base it on a couple factors..your exp and size of plant at least! if this is your first grow then good fuckin luck getting ten zips on 4 plants under a 400 lol...if you know what your doing sure thats an attainable goal but size and proper training come into play...on 5 plants at only 14 inches when put into flower i got about 6.5 zips so ya if you have some skill and go to about 2 ft then flower id call for 8-12 depending on genetics and the rest of the variables.....

The picture always confuses people. This is actually one closet, there is no division inside the closet separating the two sides. I could make a division of-course, but by default it's all one space.

I'm planning to use the T5 for veg, and the 400w's for flower. I don't really want to do perpetual right now. I'd rather keep it simple on my first grow and scrog 4 plants.

I think with 1 month of veg I should be able to get my plants 12-14" whilst training through a 2"x2" screen. They won't have to share as much light as your 5 plants did, so I'd say 2-4 ounces per plant is realistic. Especially with Pure Power Plant's genetics. The closet will be pretty much sealed (besides the passive intake hole) so I should be able to get close to an ideal environment. I shouldn't need much skill from there to get big yields.

if its your first grow id just stick some autos in 4-5in each closet at 2.5oz a plant ;)

I'm gonna cut a 6" passive intake hole in the bottom of my mylar door on the left side. I'll have 2 6" PVC elbows taped together in an "S" formation as a light break. So the closet will still be light leak free.

Your cooling/extraction setup doesn't make sense. I'm surprised nobody caught this. There are a few wrong things:
- You are pulling air from both the carbon filter and the reflectors. So you are pulling filtered and unfiltered air. If you intend to filter all the outgoing air, then the carbon filter has to be the only "exit".
- You're pulling air with a 240cfm fan (the top one) from a 440 cfm fan and another 240cfm fan, WTF? the 240cfm boosters don't make sense.

My recommended setup would be:

[carbon filter][integrated 440CFM fan]====[1st air cooled reflector]=====[2nd air cooled reflector]======> outside

I'm sorry to say that you possibly bought both 240cfm boosters and won't have to use them. Putting them in line with the 440CFM will probably only fry the 240cfm one. Maybe you can use both of them in parallel for an active intake, but passive intake works fine.

The passive intake hole will have PVC pipe with a dust shroom connected to it. Everything other than the passive intake hole is completely sealed. The boosters are to pull air through the bulb and cool them..obviously. The carbon filter should never be an "exit", because that would require you to blow air through it. Carbon filters are designed to have air sucked through them.

I didn't make a bad purchase with the boosters. Passive intake will work fine, yes.

So the ventilation plans have changed a little bit as we put everything together. Not much has changed, but It'll be something like this.

Now I'm going to be doing 2 6" holes in the ceiling. One vent hole for the light cooling, one vent hole for the main exhaust fan.

Main Exhaust
{sealed closet} <-- Carbon Filter <-- 440 CFM Fan <-- Less than 2' of ducting supported by shelf <--Ceiling Vent Hole
Passive Intake
{leading into my room} < -- 6" hole in mylar <-- 2 6" PVC Elbows connected in an "S" formation (light break) <-- 6" Dust Shroom
Light Cooling
{sealed closet} <-- 240 CFM Booster Fan supported from ceiling <-- Reflector <-- Ducting <-- Reflector <-- Ducting <-- 240 CFM Booster Fan <-- Ceiling Vent Hole

Should be finished by tonight. Hopefully that depicts a clear visual.

Also, good news :mrgreen: Got my timer FINALLY lol..Greners wasn't to quick in replacing that.

disclaimer: i'm not trying to be an ass, just trying to be helpful here

In the diagram above i've added unfiltered air (red dots) and filtered air (green dots). As you can see, you are getting filtered and unfiltered air to the outside. In your new setup you won't fry any fans, but you still have an unfiltered air circuit ("Light cooling") and a filtered air circuit ("Main exaust"). Hope this helps you understand your issue.

You're not being an ass, notice the red text in my OP. The closet is completely sealed apart from a 6" inch hole in the mylar with 6" PVC pipe leading to my room with a Dust Shroom attatched to it. Therefore, all of the air in my closet is clean. I do not need to scrub the air that goes through the lights. I only have 1 scrubber for my main exhaust fan to dispel odors into my attic. Also, don't go off that diagram anymore because the setup is working out differently (refer to post above).

Got some progress pictures. Still waiting on mylar to be delivered. I'll seal er' up and test everything soon as the package comes in :mrgreen:

Don't have enough money for CO2 yet btw. Hopefully will have that soon, only need a few hundred more.

this is a sweet set up. are you going to flipflop the lights?..also where are you sending the air from the lights? because you said you dont need to fliter/scrub it. but i highly recommend it. if your sucking air from inside the grow area IT IS GOING TO STINK.

Thanks man! No, I'll be running them both at the same time. I'm actually going to put the dust shroom on my booster fan as opposed to the passive intake, so they will be filtered but not scrubbed. I figure since the room will be sealed and my main exhaust is strong I won't need 2 scrubbers to keep smell down. I have no problem purchasing another filter later on down the line if need be, but I just don't think it's necessary.

Also, I've ordered 1 Hortilux Metal Halide bulb, just one. This is because I'll be vegging one side with the T5 and the other with a 400w. This will be a nice side by side comparison to see what I'd rather veg with. I'm also using Bud Candy on one side to compare taste/smell differences. I figure I may as well get some experimenting done on my first run haha.

you really dont need two scubbers just use one: (scubber---light---light---exaust fan out). how many CFMs is the main exaust fan? also whats the size of the room LxWxH? not sure how many grows you have under your belt. but you NEED this setups exaust to blow CLEAN/non stinky air. and that lilttle bit of air from the light WILL STINK YOUR SHIT UP! i dont care if you have only one plant in there ITS GOING TO STINK when it starts to flower. your safety should always come 1st if you dont want to get busted and
you dont want to get busted right?....RIGHT?

I'm trying to think how I would re-design everything..My fan is 440CFM, room = 9'4"x22"x7'9". This will be my first grow, as you probably assumed haha. Yes..you are right. I now know how necessary it is to scrub all the air leaving my room.

Agreed. You can use the boosters as intake fans now to get your fresh air pumped in.

its all good buddy thats why were going to help you get this shit done right.. ok your 440 cfm fan is more then you need for that size room. hook it up like this and patch the other hole up..use negative pressure to bring in fresh air. if you dont understand let me know ill try explain better.
