5 plants(not fem seeds) i`d say aleast 2 males so 3 plant total wet weight about 200g? if that!
dry 30g to 40g?!
am not even using all ten bulbs only 6, when i had 10 in there temps where way to high so 6 seems to do the trick, theres 4 at 24w and 2 at 20w thats a total of 136w
i would say no more then 0.2g-0.5g if am lucky per a watt dry!
