I was reading up on all the different forms of hydro and there is one that uses a constant drip ring throughout the entire grow. Supposedly the fastest growth too. Who knows
. I removed the drip ring all together once the roots hit the water. It seemed like a lot of nooks and crannies for bacteria and nasties to hang out in.
The plant I initially made this thread about is still going. Probably around 2 to 3 weeks left. This has to be one of my easiest grows ever. No problems except for one week when I thought I could get away with just topping off the reservoir. Leaves got nasty. Buds are rock hard. Could be genetics too. 20/20 vidamints.
