This grow is almost done but I wanted to show "The Ultimate" for its full potential. This is a vertical tree grow, vegged under a 600 watt MH for 6 weeks at 18 hours on. System is as follows: 4 - 5 gallon buckets 30 gallon Rez Grow Rocks DWC with 60 gallons per hour of recirculated nutrient solution from top feed tubes for each bucket 110 litre air pump for 4 buckets and Rez General Hydro Flora series (measurements based on 30 gallon Rez) as follows Start nutrients vary from plant to plant so ive left that out. Start the nutrient cycle below once the plant enters into vegetative growth. Veg for 6 weeks Flora Micro - 120 ml Flora Grow - 180 ml Flora Bloom - 60 ml Floralicious Plus - 30 ml Flora blend - 240 ml Superthrive - cap full Hygrozyme - 240 ml...expensive but do not go without in hydro systems Bud 7 weeks with 1 week flush Flora Micro - 120 ml Flora Grow - 60 ml Flora Bloom - 180 Floralicious Plus - 30 ml Flora Blend - 240 ml Liquid Kool Bloom...30 ml weeks 1 & 2.........60 ml weeks 3, 4, & 5 Powder Kool Bloom...6 small scoops weeks 5 & 6.....the scooper that comes with it has a big and little end, use the little. Hygrozyme....use 240 ml through veg up until week 7 of bloom Superthrive - cap full Week 7...flush with FloraKleen for 2-3 days...then empty and put fresh ph balanced water for remainder of week. I started using FloraKleen first because the taste was better and bud smoked easier when I switched. I usually change nutrient solution every two weeks...only adding what the plants look like they need in between to the Rez. Each plant is different but a great starting point is about 1/3rd of the full dose. Ph starts at 6.5 and I let it drop to 5.8-6.2 on its own. That's about it, any questions just let me know.
