Hello. I have 20 x 11litre pots with Light of Jah feminized and Cheese feminized. I use 600W HPS + CO2 800PPM with ultra reflective foil on the ceiling and walls and white foil on the ground. The temp is 25 deg. celsius and humidity is around 55%. The Ph level is 6.8 - 7.5 in the pots and I measure an even 7.0 in the water. Water is well oxygenated and growmix is light enough so that the plants can breathe. I give them nutrients according to what's written on the package and not a drop more. I can say that conditions are as perfect as they can be. Realisticly said - what yield could I expect per plant with Light of Jah and Cheese? Thanks
