there is places that do get 24 hrs sun light for a little while anyway.
while I dont think 18/6 or 24 hours makes that big of a difference would probably just stick to which ever you are using.
think 1 large plant could easily yield the same as your previous grow with 4 plants but not only is lighting important so is the strain used high yielding strain versus average or low yielding strain would also affect yield.

The plants in question are femminised white widow and are about 2 inch tall now and have been growing quickly for three days under this light on 16/8 do you grow them for four weeks like this and then put them under the hps bulb straight on 12/12 or do you let them grow so big and then put them under the hps for 18/6 for four weeks?:confused: This Rating: 5
