yield is somewhat dependent on the genetics, as well as your growing conditions. we use 5 gallon buckets filled to the brim with good soil. no ferts for 3-4 weeks, only use organic ferts and then lightly feed every other watering, (we add in molasses the last 2-3 weeks in addition to our fert use) and run the lighting 24/7 for 5 weeks then 18/6 until finished...the last two days we go 100% dark.
