Hey CG got a question, with your current setup being drain to waist! How long can you go between waterings?
And do you go feed, feed, water or some other feeding plan?
Sorry for the delayed response. We've been busy updating the A/C and getting the CO2 thing going.
I like to feed with every watering, but I'm continually reducing my nute concentration. We finally picked up a Blue Lab TDS/PH monnitor. We also started using just EC, rather than PPM. There are 2 formulas for going from EC to PPM, and the results are around 400ppm different. Fuck that. For a while I was feeding at anywhere between 1.5 EC and 2.0 EC. This is too hot. I then went to just 1.5 EC. This, too is too hot. Now I feed between 1.0 EC and 1.5 EC. Basically 1.5 EC during peak bloom time (week 2-5), and 1.0 EC during Veg, transition, and late bloom.
We are now using rockwool croutons/perlite mix at 2:1. 2 Gallon pot were big enough for 2oz plants. But, with dialed in nutes and perfect pruning, some plants are getting closer to 4oz. Therefore, we've stepped up to 3 gal pots. The larger diameter containers, combined with aggresive upper fan leaf pruning in veg, are creating some amazing multi branch plants. Of course, this settup is very similar to Commercial J's settup. He uses 1.75 gallon pot, though.
We're updating the A/C to 21 seer inverter ductless mini splits. These were the most energy efficient I could find. Yesterday we added booster fans to the air inlets on the ducts feeding cooling air to the lights. The cooler the lights are, the easier the job is for the A/C's. This is the spring overhaul I've been planning for a while. I knew this summer would strain our current A/C's. We also wanted to seal up and start adding CO2. While the D-Bub and the Tahoe grow great w/o added CO2, the Pre-98 actually doubles the yield with CO2. After it tested in at 21% THC, our Pre-98 went into mega-demand mode with our patients. We just couldn't produce enough w/o CO2 enrichment. So, next Saturday we make the change from fresh air cooled to sealed and enriched. Most of my past grows have been CO2 enriched, and I'm looking forward to the explosive growth. I am glad we started out w/o CO2. This allowed us to 100% dial in the 3 strains. Now we're ready to see what these girls can do.
