just an example, in a perfect kinda way/world
room size
12 x 12
4 - 4' x 4' trays each with a 600 watt light
total watts = 2400
total plants 128 plus 32 clones rooting
sog prepetual
32 lolly-pop sticks averaging 1z a piece every 2 weeks = 2lbs every 2 weeks or 8lbs in an 8 week period with the cycle continuing.
this would be 896g with per 600 watt or 1.49g per watt (yeah thats questionable right)
filling the same room with monsters
lets go with 4 plants per light or 1 plant per 4sq foot
and lets say that you have to veg them for 4 weeks and flower for 8 weeks to get 1lb per plant
that would be a total of 16 plants with the same 2400 watts of light (600 x 4)
this would turn out 4lbs from each light every 12 weeks so about 4lbs every 3 weeks on prepetual.
again this is questionalbe but, this would equal 2.99g per watt.
Now both of these ideas are possible but I dont think that 4 monster plants would produce 1lb each under a 600 watt light, mainly because I have never seen anyone claim more than 2g per watt. I am not saying it isn't possible but I would venture to guess that the sog system would be a little closer to realistic.
Oh yeah you also have to consider the number of plants that you have to deal with in a prepetual sog vs the amount of plants grown in a monster plant prepetual.
sog minimum for this example would be 128 rooted plants and 32 clones with possible roots
monster plant example, 16 rooted plants with 4 - 8 clones (if using mothers), or 4+ seedlings
Hope that helps for figuring out which way to go.
and no i dont run either system the way it is proposed in the example.
