I found this in my res, I'm pretty sure that its a problem with GH ph up. I noticed this slime building up in my clone machine and in my 9 site veg UC system a couple days ago. I changed the water in my veg system and gave up on the clone machine. I only added a little ph up to it and it turned...

I got some new coolcoils from HI because they are now 30% bigger, what's cool is they are the same price. I run Ice Boxes so I can't run my water below dewpoint which is about 60 degrees. At 60 degree water through my coils my water temp stayed at about 70 to 72 degrees which is a little high of...

Sizing a chiller for UC systems There's a new section of the forum called cooling system design, CCHQ started a thread there asking about sizing chillers for the UC systems.Very good info there, here's is the link

CCHQ How is that plants in the same system, exposed to the same water, same temps, same lighting, same areation, etc behave differently? For an example when I was dealing with pythium some plants seemed to be less effected or not even effected at all. Another example is when they are in veg...

I actually made of these for my reef tank so if the water gets too hot it will turn off my lighting. My UC system needs the same thing. There are overheat sensors that are designed to shut off lighting that work off of air temperature but aren't made to be submersible. Since water temperature is...

I made these and really like them. Basically I added a couple of 2" pvc caps to a 3/4" pvc tubes with screws. I covered the screws with silicone so it wouldn't leak around them. I drilled a tiny hole in each one and then attached it to the UC fill tube. I add ph down, up, nutrients, additives...

I'm sure that you all have noticed that our air pumps create heated air that we then inject in to our systems, systems that we are trying to cool. I added this product to cool the air and it works great. Its made for water but works great with air and comes with its own fan already mounted...

I've used these ph controllers for aquariums and aquarium dosing pumps to dose ph down in my UC. This system works really well together and is pretty affordable. I have the ph controller mounted to the wall near my system and the ph probe in my first bucket. The dosing pump plugs in to the ph...

Maybe someone has already posted pics of these but just in case they haven't...here ya go! I saw these in Denver at the indoor gardening expo, I went ahead and ordered all new lids to replace my old lids. They are really strong, I have stood on mine a few times and they barely flex. The...

Since I run co2 I've kept my air pump outside my garden in my equipment room. This was fine during the winter but now that its summer time the equipment room is heating up to roughly 110F. The other day I went to check on my girls and the air pump had stopped, it over heated. I took it inside...

I'm new here but have been growing for almost a decade now. I have used dirt for most of the these years because I hadn't had much luck with hydro. I tried it in the very beginning but didn't know what I was doing I wasn't very successful. I switched to dirt and never looked back. I partnered...
