    Lights too close or 1000W too strong?

    Hey guys I bumped my 11 and 7 day old plants up from 750w to 1000w today and the 7 day Dutch Treat is starting to lean and grow away from the light and leaves are drooping. The light is 33" away from the tops, is it too close or too much power for the 7 day old plants?

    Rules for magnetic ballasts?

    Hey folks, I got an amazing deal on a used 1000W HPS system, 48" reflector, MH/HPS magnetic ballast and 2 HPS bulbs. I'm thinking that 1000W is a little much for 2 plants, which is all I ever have growing, can I use a 400 or 600 bulb with the 1000W ballast? Or is that a no no? Also how much...

    Air Cooled vs Non Air Cooled

    Hi all Im planning a 5' X 5' X 7' tent with a 1000w MH/HPS combo. This will be my first run with the 1000w (previous 600w) and I'm worried about heat. So i guess the question is.... is it better to go with an air cooled hood and a passive intake on the tent or a normal hood with active...

My fear with the Gavita is that I will not be able to keep it...

    Using American 1000W digital ballasts in the UK?

    Hi all, Apologies if this seems like a stupid question. I've noticed the price of 1000W digital ballasts (specifically the Quantum Series dimmables on fleabay) in the US is massively cheaper than in the UK (even including shipping). Would it be possible to use these in the UK with a 3 pin...

    D.I.Y. Grow Light 1000w

    Hey all, I have been reading alot about people wanting to build their own led grow lights. Gonna take a crack at it since the led grow light prices are going up, Being on disability ya cant afford much so this will be around the same price as buying a 1000w hps.

    I'm considering switching from horizontal to vertical

    My bloom room is 4x8, 7' high. I have a 1000w HPS with adjustable ballast, plus two 400 watters--one HPS, one MH--that currently share a hood but can be separated. Adding more lights, beyond maybe some low-watt CFLs, isn't an option--I'm maxing out the circuit that powers my barn, where the...
