I'm working on it now ray. Building up my clones and making things to put them in. I don't want to do ebb and flow so I'm making a set up with buckets that recirculate off a central res. So I can do 6 plants with one res and make it easier to keep track of (nute wise and such). And 3 setups to have 18 plants at a time with a staggered harvest. I have 2 big plants I'm waiting to finish (3 1/2 feet tall) so I can rearrange things. Went and got a new light set up today. 600w Lumatec digital ballast, fancy store bought reflector and an Eye Hortilux hps bulb. My last harvest went to market (not all of course) so I had the cash to buy it. So I'm going from 50,000 lumens to 95,000 lumens. My 400 is an old warehouse fixture that I rewired to run the bulb seperate. Just an old magnetic ballast. But it worked and grew me enough stuff to be able to use the cash form that to buy the new one. Three of mine stretched like that too. I think it was just not enough light intensity, They vegged great under CFL's. Nice and bushy but when they went under the HPS is when thsy did it. Maybe just not close enough. And to big of a space for the 400w to cover. But I think I've solved that problem now. My last 2 did real well but spent most of their flower time in a box a little over 2x2 feet with the 400w light. That's a lot of light for that size. We'll see how the 600w does.
