Grow Box For Single Plant?? Need Advice!!

[wman44]

7ft tall eh?
that should provide you with plenty of headroom for ventilation and your gonna need a door of some sort.
so you've got 12sqft of floor space
your gonna want 50-75 watts per square foot for a total of...600watts. get a switchable ballast that way you can veg and flower in the same box unless your planning on building a second chamber for veg.
also it just occured to me that if you divided your space in half you would have two, 3ft by 2ft areas for a perpetual harvest. id put cfl in one half for germination and veg and a 400watt hps for flower in the other half.
really with that much space you have lots of options

Dude, tip that bitch over on it's side!


3ft deep, 4 feet high, and 7 feet long!

OMG you could have a huge crop.

[wman44]

good point maxsuperdanks!
he would need two lights or a light mover though

If I cut the box down to 2x3x6, you guys think 400watt and about 3-4 plants?

[wman44]

400 watts will do it
the number of plants you grow really depends on the style of grow your going with weather it be lst, scrog, sog or whatever and your amount of veg time.
you could grow one monster
2-4 smaller plants
you could even grow 50 single colas with a sog(sea of green)

You think I can get a couple ounces outta one plant that size given the right conditions.

The Box you have designed is Fine, But what-ever light system you go with you have to have good air exchange or it will not work!!!

You should shoot for 4 or 5 plant's and not worry about being 5' tall and have 4-5 at 2'or 3' tall. If heat is going to be a problem? Don't kid your self? That many CFL will put-off some Heat!!!.... My 2-cent's would Be, Go with the 250w. HPS @ get 4-2by or even just single's T-5 Tubes, But any-way put one vertical in each corner.
Since you are so tall make a sub-floor at 12" from the floor-( so you can recess a CFM-fan in the floor ( vent around the very bottom out-side walles of box with cornis vent's they come 3" @ 6", use the top for a fan oscalating down, and very-top exhaust-out. And I bet your result's will Shock-You!!! THT'SMY2CNT'S. Good Luck!!...Later

Thanx for the input! I rebuilt the box 2x3x6. Somebody said 400 watt hps, someone else said 250, I'll prolly go with the 250 so save on ventilation issues, I already got some 40watt T12 4' fluorescent tube lights, 3 of them to be mounted on the walls,1 each side and 1 at the back for, are t12's to big?

I think you have came to a good solution!! I feel the air exchange and good air flow are just as important as right lighting. Hey what the F.*&%$#'n you waiting for GET Some GREEN In The ROOM!!! Later
