I Love DWC (Deep Water Culture)
Over the 15+ years I've used it, I've noticed a few things which can be added here. These make your experience much less frustrating. ;)
- Your nutrient solution must be between 65F and 69F for the fewest hassles with biological activity and root rot.
- Airpump size should be a minimum of 1 Liter per minute of air, per gallon of water, or 3 watts of airpump wattage for every 10 gallons of water.
- Cannabis is an accumulator plant, so using nutrients which are not pharmaceutical grade, or which are not properly balanced for cannabis will reduce quality. Cannabis is pretty good at accumulating heavy metals, commonly found in AG and cheap nutrients. (Most plants don't absorb them, so nobody cares. Cannabis does, so be aware.) :D
- Keep your nutrient solution the same level, topping off with fresh water once a day. When roots adapt to no water, and then are soaked for a while, they tend to rot. ;)
- Airstones are better than open lines, and science agrees
Cannabis LOVES Deep Water Culture!

My Pleasure! :D
icmag.com has a lot of growers in the UK. Hop on over there and start reading. :D
Also do a search for "Ask Lucas" and read the entire thread a hundred or two hundred times. There are gold nuggets of information in that thread. Combined with how cannabis is an accumulator (look up hyperaccumulator and phytoremediation), you'll be way ahead of most growers in no time. :)
