SOG Grow box - My first time and I need help

The CPU fans would input from the bottom. Cooler air.
There may or may not be a fan inside to circulate.
There will be a vent (exhaust) at the top with a scrubber that will vent with my dryer outside the house.

Blink - I don't know how to say this real nicely, but this plan sucks in so many ways. But that's ok because many initial plans suck, I know mine did. Until you actually have a bulb burning inside a box you don't really appreciate how hard it is to get the heat out and how much ventilation you actually need.

I really think you should go to the cabinet/closet section and do some reading about grow boxes and ventilation.

To use a scrubber, you need a fan attached to the duct the scrubber is on. passive air flow won't work. Most scrubbers connect at the end of a duct. i.e., they don't go in-line where you have duct -> scrubber -> duct.

And fans inside your box are a definite must. The plants need/love air circulation.

Thanks.

I will read more on fans and circulation.
I am concerned about inside temperature.

blink - I'm glad if I can help! I'm just a couple rungs higher than you on the noob ladder, so I don't know a whole helluva lot - yet. However, I am pretty good at construction - you can check out my latest grow cabinet here - and the mistakes and lessons of starting up are still fresh in my head.

So a little update,

I went and picked up a 16 cubic foot rubbermaid container and lined it with black/white plastic. $99.00

Picked up some 4" fans at hardware store and mounted them on the inside with cable ties by drilling through the box. $18.99

Found some full spectrum flourescents at the local homegrown hydro store 3 of them give 15000 lumens. $95.00

This "room" will be my clip to veg room as I can only veg until about 14 inches. 2 mothers will be held in here as well. I can fit 100 clipping s plus the two mothers without overcrowding. Right now I have 12 sprouts that are 5 days in and have now pushed all 4 starter leaves and stand about 1.5-2 inches high.

Hopefully I can build a decent 4 x 8 box as mentioned earlier in this post to flower.

Has anyone ever worked with minimal height before???
I figure that I have only 28 inches from top of soil for plant growth....I will be clipping the bottoms to maintain order and space hopefully ending up with solid 28inch colas...

If you have worked with this height before, what sort of yeild can I expect??? 80 plants in a 4x4x8.


Still having fun,

Wow...fan off 102F, fan on 94F.....tops are 6" from lights.
6 days in and the 6th leaves are showing. pics to come soon.
Tips are a little brown. Heat might be playing a factor here..
