Hi all. This is my first run using pool shock for a sterile res. Had everything going well, introduced my plant to my RDWC system, had it running well for about 1-2 wks. Added pool shock of .9 grams for 30 gallons, and within 3 days of adding the shock my plant took a dive. Before and after pics...

Getting a new round going and have my system all ready for my next batch. Went to add the seedling to the net cup and saw my tote was foaming. Res is crystal clear. I did make changes this run. Went from using H202 to poolshock. Also added monosilicic acid before any nutes and let sit 24 hours...

So, revamping my whole thing. Small grow for 1 person, not me but the better half due to me still being randomed. Anyways, had a 4 site waterfall thing going and the plan never came to fruition. Would only get 2-3 plants plants to grow, pain in the ass to get to the back of the tent to tend to...

Looking at this last, which is constantly evolving, who is your favorite breeder?

I currently have a 400watt HPS in a cooltube, and want to upgrade to either 600watt HPS, or a 400watt LED like the attached. My area is 5x5, but usually only utilize 4x4 of the area. Heat is not an issue as the ambient temp usually is around 63f year around outside the tent. Actually have to...

Sorry in advance if this has been asked/debated. Searched and really didn't find an answer. I've been using my well water and have had mild success. The ppms are high so I can never really add a decent amount of nutrients to my res. Usually 5ml of micro and 10ml of bloom of GH nutes per 5...

Have a RDWC/waterfall system, 4 site with 17 gallon totes, 2" pvc return to a 20 gal res. Water levels were falling everyday and I thought it was just due to flower cycle. So I kept adding 5 gals everyday to keep res up to level. Then noticed lots of water in my tent. Thought maybe dehumidifier...

I have a Cooltube currently running a 400w HPS, and want to upgrade to either 600w or 1000w. If I get a new ballast and bulb, will the same cooltube work or would I need 1 specifically for that ballast? Picture of cooltube fixture rating for reference. Pretty sure it would but want to make sure...

In middle of a low pressure aero rail grow, and am not happy with the rail design and res being in the tent. Thinking about incorporating RDWC waterfall design, but instead of water just falling into the buckets and recirculating back constantly with the roots constantly in water, I'd make more...
