I am new to growing

[Choice]

I have a pretty nice set up this is only my third crop but i recently did a 3 week veg and now Im under 4 1000w adjustawing lights with 12 plants ny sour d what kind of yield shoud i expect? my room is maybe 12x12

introduction of the room...lol...newazz sound pretty ligit using 4 1kw on 12 plants...i guess you got lot of money to spend on the bill...

Between 0 and a whole bunch...
Expect .25 grams per watt.. but I will bet on more.. depending on too many variables... I always figure .25 ...always a pleasant surprise.

Welcome to the farm Choice

Yeah That sounds like A lot of light for a 12x12 room..

Hydro I assume?

Got Pics?


:bong2:

4000 is too much for 12x12. You will be chasing your tail with air movement and cooling and the electric bill. Instead of spending all that extra dough on electricity get some CO2 with a sniffer going.

2K watts is PLENTY for 12x12. You could place the lights in a diamond and flip back and forth from between 2 sets of lights for better coverage and to cause them to turn and strengthen stalks.. but not 4 at once.

I grow in a 12x12 and have experimented from 1K to 5K, and 2K is best all around IMO. I've also found I can make 2 or 3 trees yield as much as 12 in the same space.

2000 for 144 ft²= 13.9
This isn't the pic I wanted but close..

4000 8x8 bit under 5lbs cure wieght with decent trim not left larfy
Never done the math...
8x8 64ft²...4000/64= 62.5 w/ft²
5 lbs 454= 2270
4000/2270= 1.76
This is math on 5, I think it was about 4½+/- so 1.5 ish... gpw
MORE LIGHT!!
YOU WANT 40 W/sf² minimum IMO
... man I hope I am not over medicated and forgot how to figure light density...lol
I'D LOOK DUMBERER..

I second Trefarmer's lighting calculations- 2000 watts is drastically insufficient for 12x12, and even 4000 watts is marginal. The standard calculation for 1000 watts is 4x4, or 16 square feet. 12x12=144 square feet. 144/16= 9 lights to get similar lumens per square foot. Yes, it's true you'll need to actively cool such a room, but that's hardly unusual. Look around the Farm, you'll quickly see some of the most productive gardens adhere to these rules.

There are some cheats, and I'm working on one. But if oyu want yields, you need light. And it doesn't matter how many plants you have, if they're big enough to cover the area they're going to give you yield.
