Lots of questions.
Lets see I use Bio Nova coco-brick and Canna coco a&b, pk13/14, epsomsalt, rhizotonic and cannazym.
I have three 90l reservoars for three 400W HPS lights. As it looks now I will have about 5x4 (20) sog cuts per light when it's dialed in. 100x80cm per light. But nothing is written in stone.
I flower seed plants in 3.5l pots with varied veg time for different plants depending on space. I flower sog cuts in 100x20cm slab trays, 5 per tray, coco directly in the tray instead of slabs with a slight angle to help the nutriend flow back to the reservoar.
I have a little too hot in my growroom (have new ventilation purchase planned) as you can se a little unwanted foxtailing on the buds. So the plants drink more water then nutrient so I add water as needed and it can be quite alot. I can add up to 90l pure water to the original 90l within a ~ 2 week span (I'm guessing here) and after that I change it. Then it's about 20-30l left. I have to check EC everyday if i want it within +-0.1 mS/cm but im too lazy for that. I check it every 3-4 days and add water, but then it can be up to 0.3 mS/cm off.awesome one more thing, or actually a few
how often do you have to refill and maintain the rez? is it a lot of work? i gotto do a round of something automatic some day.. if not ill go crazy hehe i handwater about 100L or more every 2 days.
