What are the effects of doing this in such a way as to keep all the lower leaves in tact?. In other words can you keep all lower leaves and have them direct energy to the top.
its getting that energy to the lower leaves in the first place
thats the issue, weak COB's , small hids, cfls even T5's all are great budding lights
but penetration is shit
any more than 6-12 inches from the light
the light(lux) levels are too weak to stimulate any photosynthesis
for this reason its best to remove stems leaves(cuttings)
once snipped, shuffle them to your DIY bubble cloner
for 10 days of rooting, then shuffle your original plants to your bud room
as the lower cuttings now clones are moved into your current space
good luck
