So after reading about DWC last summer I decided to set up something simple and test it out on tomatos seeing as growing marijuana here was still illegal in Canada . Trial run went awesome with minimal problems. So I had to try one marijuana seed in the system after all was said and done. For a first time all things went well except for when I would change out the water. I'm just wondering how often or of at all people do full water changes in a DWC system. Any feedback would be greatly appreciated. Cheers
