77 degree water. No root rot.

I have 77 degree water in both rdwc and standalone dwc. I have never had any root rot issues. Ph issues but no rot. I use a lot of air. Like 1.5 watts a gallon. Big metal pumps. I also use h202 on occasion, but not religiously.

I have been having great growth. So well that i have ignored the res temps! My ph probe tells me tho, I finally looked down 2cm at the probe face and smiled. It has to be all the air.

I wish I could afford a chiller. I always want to do ebb, but I am a legal medical grower and trees are the only way to make this worthwhile. I know how to ebb five gallon buclets but 20 gallons of hydroton seems kinda a pain in the ass.

On a side note i just built a two line rdwc and except for the temp, not a prob tho, I will never look back.

I run feed lines thru the top and pump it back out the bottom. So clean.

ps dont you guys love doing a fresh run in a clean white tent? cool

Thats a pretty high temp for no root rot. My res temps were hovering around 81 with lights and 74 lights off. Root rot was developing so I had to cut some of it out. Maybe I'll need to invest in a better air pump.

I've heard of higher reservoir temps never causing poblems, but the 1 constant I've seen to make it work is big air pumps, my reservoir runs at 74 to 77 degrees with no issues. But I run a 320 gph air pump with 8, 6inch air stones in 2, 18 gallon reservoirs. I'm thinking about tunnung two more cheapie air pumps to my reservoirs, to get even more air.

I run a 150/lpm air pump to 6 6in large fired aluminum stones that are capable of 10/lpm each. and at 77 no root rot but if you start to creep over 80 you have to watch it. if I am at the early stages running straight water there is usually not an issue but once I have to add nutes and the temp is over 80 then I start to run into problems. the more air the better for sure. but to obtain higher res temps you deffinately have to make sure theres no light leaks.

all good adivice. I posted because I am always a little nervouse. I am trying to battle 100 degrees here with a room ac and a semi house ac model. I keep it down to 70 or so and I try to keep the airpumps near the ac! That helps. In winter I will have natural temps of lower than 50 or so.

I keep thinking and this was the second whole run I made in five gallon dwc. Something was wrong with the roots i feared. Not rot. Just when I pulled the plant they seemed smaller. I abused them as they were a test run tho. So I am always paranoid about plants. Usually tho I am right. We will see.

With my rdwc the feed lines shoot the roots with a highly oxygenated solution. I hope for the best. I put the airpumps in the grow tent once not long ago. The air got hot in there as I was running co2. The water got pumped with hot air. It was not cool like 77 to the touch but warmer than warm. Plant began to wilt.

My first grow was in dwc, my water temps were in the mid 80s for most of the grow, buckets weren't opaque, I had to h2o2 a couple times due to I hate brownish roots but other than that no problem, my room temps were mid 90s too.

Do yourself a favor and buy one pump that will handle all, sunleaves durapump 950 gph sells for under 50 bux, I actually saw it just the other day online for like 35 bux
