How would you slice it?

[peaceful]

I am separating a grow and veg space in a closet. The space is 41"w X 48"d X 8't. The bottom has an 8" step up 2' back from the front.

I am going to put a shelf over the whole floor at about 24" from the floor at the front. This will give me a veg area underneith and in front of the step up that is 41"w X 24"d X 24"t. I have 40k lumens of 6500 t5 that will cover the top of this area completely. I would like to put 9 or so in 1g containers here with a clone station. I figure they can get 1' tall here before burning on the fluoros.

That would leave 6' of height in the upper portion with a flat 41"X48" floor. If I use 3g pots here that are 12" tall, I figure 12" from ceiling to bottom of light, 18" of clearance needed beneith the light, That only allows for a finished plant that is 2'6" tall.

So the ?'s

-Is 22" floor to light enough height for the veg area?
-Is a 1' veg and 2'6" finished height for the girls pose any problems?
-Planning on a 600w dig hps for flower with air cooled reflector. Is 18" as close to this light that the girls can get?

And lastly, I will probably put the new floor/shelf on an angle so I can use it for flood in the future, anybody know how much slope I need? 1" drop in 4'??

BTW, WW and bonus bean crop in the works.

Hey peaceful, to answer your question about the room needed for the 600watter. There is no set distance that u need between your tops and the lights. That all depends on the heat being produced by your light. And if u air cool that 600, u may be able to get the light pretty close(4-8" away). U gotta go by the temps at the tops. A good rule of thumb is, put ur hand palm down over the tops of ur plant, and lower the light til its a lil too hot for ur hand, and then raise it up 2 or 3". If its too hot for ur hand, its too hot for ur plants. Keep a thermometer dangling at plant top level, and monitor it. U dont really want the temps at the tops of ur plants to exceed 85* (mid to upper 70s are ideal). The key is, GOOD ventilation. I hope u have a good inline centrifigul fan(not duct booster fan) to pull that heat out. Hope this helped.

Btw, i have a cooltubed aircooled 400w and i keep it only 3 or 4" from my tops, and its a consistent 76-78*.

Also, if ur using T5s for veg, i think 22" is plenty of height for ur veg chamber. I only grow my white rhinos to a veg height of 8-10" (bout 4wks veg and after being fimmed or topped), and they grow to a bushy 4' in flower. If ur concerned bout the heights, just research and use methods like topping, fimming or lst. I fim mine in veg and they turn into 4-6 headed bushy monsters. lol
