you think activated carbon (fish filter carbon) would have any effect if i mixed it in my soil medium?
I see no real botanical value with that photoperiod. What you have is a longer than average light period, might as well go with a 24/0 or do what I do, go with a 20/4. Whatever works for you though, it's all about finding a plant's light saturation point and not going beyond it.ok this is a flood and drain hydro with perlite as the med. sog style this is on a light cycle of 36 on 12 off the first 3 r at 5 weeks
oh yeah and here is the liquid carbon i use the pet store is ur friend
Flourish Excel is a simple source of readily available organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be obtained via relatively simple organic compounds (such as photosynthetic intermediates). Since both processes occur simultaneously one can derive a substantial benefit with the use of Flourish Excel either alone or in conjunction with CO2 injection. Flourish Excel also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3). Flourish Excel is recommended for use with the entire family of Flourish products as well as our gravel, Flourite, our GH builder, Equilibrium, and our non-phosphate buffers, Acid Buffer and Alkaline Buffer.
