Re: Xlr8's Hydroponic Adventures and Photos from the Garden - 2012
for the 12-1 method -- this would make a lot of sense if marijuana were a CAM plant because you would take advantage of the store co2 it had then shut the lights off and allowed it to gather more. however marijuana is a C3 plant so i am not sure why that method is effective.
upon reading on C3 plants i found 75% of people's problems are due two main points ---
1. C3 plants cannot grow in hot areas because RuBisCO incorporates more oxygen into RuBP as temperatures increase. This leads to photorespiration, which leads to a net loss of carbon and nitrogen from the plant and can, therefore, limit growth.
2. In dry areas, C3 plants shut their stomata to reduce water loss, but this stops CO2 from entering the leaves and, therefore, reduces the concentration of CO2 in the leaves. (limits growth)
This is why temperature and humidity are vital to a successful grow.
