RHINObeast,
I am amazed that you can do that in DWC. First off, we have very clean water here (50ppm) and lets say I start off with clean buckets etc (as sterile as possible) and fresh nutes at 1/2 strength, you know a good clean start. Then I go with room temps of 75-78 then before long, especially with out frequent water changes, I get lots of indications of bacterial growth, a little slime forming, water doesn't smell fresh, roots start to turn a little less than white and it just goes downhill from there.
The less I change the water and manage the temps the lower my production and quality suffers. I see so many people using all kinds of reservoir treatments like all the preparations that are nothing more than "pool shock" and then there are the treatments like
Hydroguard which I think has some beneficials in it but everyone has their favorite way to jack up the reservoir that seems to work for them. I never had success with a single reservoir treatment except water changes, lowering temps and some H202. That is until I started chilling the water. Now my UC system is just rockin with root ball sizes and other indicators I have never seen before.
Anyway, the reason I was asking all the questions is I see DWC issues with water management (mostly temperature related) on these forums all the time. I am no master grower but I know root rot when I see it and I see a lot of it here and for the sake of the folks who haven't gone to a chiller I am interested in how it works:). Went 2 years without a chiller but it was kind of a bitch.
Also, I have to manage my veg tent that will get too warm for water temps here pretty quick as Spring comes on. My veg tent is in the garage so 7-8 months of the year it is easy to manage (just have an aquarium heater in the reservoir set to 62F for the real cold days) but I need it to run during the warmer days as well. Going to get a small 1/10 hp chiller for it but can't afford it just yet so like a lot of folks I have to manage somehow with what I have......
BTW, some fine looking roots on your plants!
Thanks,
Dee
