HI, my drip system is an 8 gallon container that's 22 inches and some by 15 or 16 inches wide. A pump sits at the bottom and feeds a half inch line that goes through the top and across the middle 3, 3 inch net pots on each side with 1/4 inch line to the net pots. Hydrotron rocks in the pots and a steady flow of water 24/7. A 400 watt light is good for a 3x3 or 4x4. I just put in an air stone just to help get more air in the water and it helps cool res. Plant do not sit in the water. Just the long water roots hang in the water. At first I thought I would need 2 of these. But I veg for 30 days or until just about 2 feet. they are almost 3 feet now. that takes up my 4x4 quick. If you look at my pics. Yes you have to check it on a daily basis some times more, yes at first it seems like a lot of work but once you get the hang of it, it seem to almost run it's self. Problems show up quick and can be compensated just as quick. And yes get all your stuff together well ahead of time. I got mine off the net cheap but could have built it my self easy. I will keep my post updated to the end. Looks like maybe 6 to 8 oz's maybe more in three months. In the 6th week of flower and trichomes are mostly cloudy but some are clear maybe 20 per cent. Just waiting for buds to swell alittle more. This is my first hydro, I had no good luck with soil, used the wrong kind didn't help. Hope this helps. Over all investment will be recovered on first grow. Next grow are orange bud skunk. I will have it ready just before xmas yee ha. That's what makes the raindeer fly. If you want to know where I got my things Just ask and I will list, mind you I didn't have lots to spend so I looks for deals and do my home work to find out what is adiquit. Oh yea if you really want to listen to some one it's Zandor, He's help me alot sometimes without knowing just by reading his help to others, I don't ask for help unless I can't find someone else with the same probs. I took a small sample and must be stoned as hell I'm running on. Hope this helps.
