55gal, lightproof, aerated drum which pumps nutrient solution to a top-drip system on regular schedule. None of the solution is being recirculated. Water temp is ~62F. Does anyone have any idea how long the nutes will generally remain effective and stable in such an environment? I know it's...

@Terry385 thanks, yeah I'll give it a try. However, I've done this same 24x7 veg on every one of my previous grows (and just recently with same strain) without any issue. Feels more like an under/over feeding issue? I'm having trouble finding a definitive answer to feeding frequency and volume...

Hey guys, Long time RDWC grower here who wanted to give rockwool DTW a test run. I'm having some leaf edge curling (pictures attached) and I'm not sure what's happening. Vitals: Grow Medium Big Momma 8" Rockwool cubes Initialized @ pH 5.5 for several hours Nutrient solution GH flora...

For those who might come across this thread later, I tested out idea #1... and even with moist blocks and humidity domes, it was too big a shock for the air-rooted clones to take. It was worth a shot since I had the extra clones ready to go, but no dice. I'm going to use the traditional rw...

Yeah, move your chiller outside the tent. As long as your room is cooler than your tent, the second law of thermodynamics guarantees it will help. The difference won't be dramatic, but every little bit helps when if you are trying to shave off a few degrees. Foil or mylar and and some spray...

No problem. And keep in mind, I am not talking about organic tea bennies or anything dirty like that. It's just a few hundred milligrams of powder with each res change. A true 'sterile' res is impossible outside of laboratory conditions. Bacteria will grow, period. The temperature affects...

I used to freak out about the res temps all the time in my RDWC and used frozen bottles, etc, etc. But the res temp is not as big of an issue if you follow some key steps. My RDWC has res temps reaching the high 70s during the summer and I have never had issues. But there are a couple KEY...

Greetings growers, I'm wondering if anyone has a successfully transplanted air-rooted clones (bucket clones) directly into rockwool cubes? I understand that, traditionally, most people use starter rw plugs or smaller cubes which are then transplanted (or top-planted) into a larger cubes. But...

Seems there's a new commercial version of what I built... Claims to cool up to 30gals about 6 or 7°F But for $220 USD... might as well get a refrigerated cooler. CSXC-1 Aquarium / Hydroponic Chiller http://www.chillsolutions.com/products/csxc-1-aquarium-chiller

I did a small-scale test using CPU radiator to see if it could dissipate excess heat from a pump running 24/7. It seems that the ambient temp is key. It cannot get any cooler on it's own. https://www.rollitup.org/t/res-cooling-pc-liquid-cooling-radiator-hack.653011/

For anyone who stumbles across this later.. be sure to avoid copper or galvanized as they will leech and kill your plants, as is now well known.

A well-balanced recirculating system will have the PH climb slowly over time as the plants uptake the (acidic) nutrients from the water. In my 25gal RDWC/Drip hybrid system, I see an increase of approx. 0.1 - 0.3 PH per day. I offset with a small amount of PH-down once every couple days. I've...

The environmental protection agency (EPA) recommends 0.125 teaspoon (0.6ml) per gallon of water to sterilize it safe enough for drinking. I have a 50-gal air-tight drum that I use to hold pure RO water. I accidentally left the lid off for a couple days and it started to get some funk smell...
