I have a 3x3 metre tent with 4x 600hps on top and 4x 400hps on bottom?? Is this toooo much? What do the experts recommend? Thanks
40 watts per square foot and that's pretty good. People use 65 a square usually max. I have 67 and can turn it 73 and I have a 3x3 feet tent with a 600 that turns to 660 but as said 600 is 67 a square. Lots of people use 600 in a 4x4 feet tent and that's 40 watt a square like your setup and do great. You actually can add another 2500 believe it or not to get 65 a square. But as said 40 is used a lot and with killer results. Sent from my Moto E (4) using Grasscity Forum mobile app
I have a 2X2X4 tent and use a 65 Watt LED. I have one sativa in veg and two indica seedlings doing pretty well so far in it.
On the bottom ? how ? 3 meters is 9 feet so i would like to have 1000 watts per 4 to 5 feet so yes 2000 watts in total is perfect To pull max yields.
I would run one 600w HID system. That's plenty. Otherwise you are gonna bake the shit out of em' with heat and light. If you ain't bought lights yet, then I would run 3 of the 240watt LM301h's in there. I have a 5x5x6.5 and pull 3lbs+ off four clones every cut. Read my journal all in there. Here is the lights I run. www.alibaba.com/product-detail/Meijiu-Top-Quality-Quantum-240W-Board_62085492201.html?spm=a2700.12243863.0.0.2ce83e5f3InsPF
Na mate, just using what I always have.. I use to use a room half the size and used had 2 600 watts on top and I'd pull 3pound off 2 plants of quality!
T Thanks bud, I already have everything... I use to have a room that I had 2 600s on top and I would pull at least 2lbs up to 4lbs off 2 plants. Thanks I'll have a good look at the links! Thanks
