i run 10 plants in a perpetual grow, taking one a week, on average, and sticking a new clone in to take it's place. it takes about 8 clones ( at one per week) for them to get to the size i like before i flip them. the clones grow in a closet, the plants are in a 5 x 10 tent, with about 1000 watts of led spread out in 32 cobs.
10 weeks is sufficient for most strains, and i usually run at least three strains, so i almost always have one ready every 7-10 days, with the ones that take longer getting left in the back and the quicker ones taking their place
clones (and a couple of seedling in the middle) waiting their turn...have some more rooting up under the foliage of the larger plants below the rack
yeah, i'm a sloppy wirer...
so mine are always in all different stages...
