Hi guys

I have a very small grow cabinet. 29"w x 22"d x 55"h.
I have 2, 95w enviros, 1 blue & 1 red. that are kept 4" from the top of the plants. There are also 2, 26w enviro lights below the plants. I run the same lights during veg & flowering.
For venting I have 2, 4" exhaust fans that pull the air thru a 4" hole in the bottom of the cabinet, then thru 2, 4" holes in the top of the cabinet, then the air is cycled thru an ozone chamber then out a 4" vent pipe thru the ceiling. walla no oders.
I can regulate the temperature by how I run the fans. With both fans off the temp 4" below the lights is 91, with 1 fan on it's 86, & with 2 on it's 80 degrees. I can open another 4" hole in the bottom of the cabinet and lower the temp another 4 degrees across the board..
I use a hydro system with clay pellets. The nutes are sprayed onto the outside of the pellets and then run down the roots & back into the resevoir. The nute solution temp stays at between 71 & 74 degrees. I keep the tds of the solution at 1000 during veg & 1500 during flowering. I change the solution every 3 days.
I used Delta's grow method of training the plants.
(Very impressed)
I just harvested my first grow using the enviro ligths with this system. I grew 1 plant to 33" and got 5.5oz of cured very potent medium tight bud.
The grow before this one I used the same hydro system but grew 2 plants & topped the plants instead of training them.
I also used a different lighting system. I used 1 95w enviro (blue spectrum) to veg & switched to a 400w hps to flower. I had alot of problems with heat & the top of the plants can't get very close to a 400w bulb and in such a limited amount of space this is a big concern.
The harvest I had using the hps to flower yeilded 4.5 oz off of 2 plants.
For a small grow room the enviros have my vote.

Maybe some of the experts out there can let me know if I can use CO-2 in such a small area. I was thinking of using excellofizz tablets & letting 1 fan run so I don't get to much CO-2 if thats even possible.


Just passing it along.
