Well I spoke to soon. The roots seem to come back but after a reservoir change they are getting re-infected with the brown slime algae...even if I re-inoculate the reservoir with tea. At this point I think it is in the water supply. I have read a couple other people having this same issue and...

Hey Sputnik, Any updates on your progress or a solution to your problem. I read over your two threads and I am having the exact same issue. My water is coming from Westminster, CO. Someone else posted they were having problems with water from Denver. Were you ever able to get your water tested?

Just an update for anyone else that is reading this. I think I finally figured out what was going on after loosing 3 harvests. I believe I had brown slime algae and not pythium. H2o2 treatments didn't seem to do much and res temps didn't make much difference. I finally ended up using...

Hey does anyone know what size chiller I would need? I am going to buy one of these for the next round. I have 150 gallons between the 12 buckets. Air temps will be around 78F, res temps were like 70 or so and I went to bring it down to 65. I am thinking a 1/2 HP will be enough?

Hey thanks for the info. I think you are spot on with what is going on. Unfortunately my plants look really crappy about right now so I am not even sure if they would recover. I just decided to start over and took a bunch of clones. I'll try again in 2 or 3 weeks with a new batch.

So my plants still look like crap 't after being back in the aero vegger for a week or so. Since they were doing fine before moving them into the RDWC system, I am thinking I either have nutrient lockout or root rot. I cleaned out the system and filled with fresh water last night and they...

Installed the swamp cooler today. I ended up going with the big ass cyclone cooler and it is working pretty good. So far it is holding humidity between 55-60% when it is left on all the time. It is kind of nice as it has a 2200 cfm fan on it as well for moving air in the room. I moved the...

Here is some more evidence if this helps determine the cause any more. This kind of leans towards a humidity issue in my mind. What do you guys think? These are soil plants in the same room. The big one is an OG Autoflower and the little one is a Black Afghan that is in veg. They look a...

Yah I have never seen that before either, usually slime is at the water level. Could this be the gognats or the beneficial bacteria? In the process of cleaning everything right now.

I just noticed this when doing the reservoir change? Is this slime? This seems to have appeared a day or two after treating with the gognats, so I am not sure if it is slime or not. Also, a few of the rockwool cubes were touching the water so it may be rockwool as well. Any advice on what...

Also keep in mind that I am currently exhausting my room every 2 minutes or so via the can filter/fan, so I figured the extra square footage on the swamp cooler would be needed but I guess I won't know until I try.

They do have a cheaper swamp cooler like this one: http://www.homedepot.com/p/SPT-450-CFM-3-Speed-Portable-Evaporative-Cooler-for-100-sq-ft-SF-610/202105062?N=c4kl#.UmcaARDjJE0 It is only $180 for 175 square feet, I just planned on the bigger one because it was for 500 square feet. I guess I...

thanks for all the help everyone. At least now I have a plan of attack on correcting my issue. I really had no idea RH could affect the plants that much. I am going to start with replacing the reservoir water and running without much nutrients for a day or two and also get a swamp cooler...

ok thanks, I did start them out pretty low at about 370 ppm then bumped them up to 570 PPM. I think I might also try the cultured solution nutrients instead of using botanicaire. By the way, my RH is now sitting around 43%, not sure if I can get it all the way to 50

ok thanks. I am currently running a temperature controller that brings air in from outside with a 6" can fan when it heats up too much in the room, but I also have a canfan/filter exhausting from the room 24/7 (960 cfm). At this point the only thing I can figure is that I have something going...

Yah, I plan on doing something like that next summer. I would like to re-coup some cost first before I invest a lot more money. Here are a few more pictures, hopefully with some better lighting. There was definitely a few bugs flying around and a few dead ones on the ground. I took a look...

ok thanks for the help. Attached are a few pictures of a the plants. I am running an open system so it is kind of hard to do CO2, however the fan replaces the air in the room about every two minutes so there is a constant source of fresh air. It might be kind of hard to get the humidity...

Room temps are pretty constant at 75F lights on, 70F lights off. Humidity is around 30%-40%. Not running co2. Reservoir temps are sitting around 70F. They did get up to 74 F for about 2 days, however I have corrected that. Does my water level sound right then? An inch or so below the...

Also, one other thing to mention that might be of importance is that these were all cloned in rockwool cubes, so I basically put them in the cch2o netcups and put the water level right below the rockwool cubes about 2". However I did notice that when I did this, the water level is still way...

ok, thanks for the response. That kind of makes sense of what might be going on how long do you think it will take them to come around, I kind of feel like they are in shock right now. Also, I am currently still in veg state as I planned to veg for 3-4 weeks in the cch2o system until my...
