Hmm pappy, lets find out why your getting pythium. What are the res temps?
======>I finally got my coils and silicone tubing and am playing with it today. I'm hoping to maintain 64 - 66 , it would get to 76, 77 using the ice cube method :-(
Do you have good aeration in the res?
=======> It was too good, the surface was so turbulent that I found long pieces of healthy root. On that, that brown **** was quite localized and elsewhere the roots were white. I've removed the bubblers and just drop a tube in to each rez. The monster pump boils those two little buckets. The plant buckets have a tube down through the pellets that drops water in to the bucket from res about 2 in below net pot.
Is there light leaks?
=====> both rooms 24hr veg
We gotta find the problem, fix it and not have to spend 100 bucks. Go get some H2o2, the 35% kind (mix it 50/50 with water). Dip the roots/basket in it for a few sec and then into clean water, do dips in each about ten times (making sure you get all the roots up to the stem) and then set the roots/basket in clean water, then get some rubber gloves and use a 50/50 mix to clean everything well, then reload res and put you plants back in. >>> 50/50.... wow. That does sound better that what I'm trying. =======>Thanks as usual.
