Thanks for the input but both for financial and for experimental reasons this grow will have only the three Procyons (not sure if we posted about addl. lights but i could be wrong, there are two of us here).
As far as inter nodal stretching is concerned, with 5-leafs sprouting average is about 1/8" to 3/16" between lower branches. And the testing that we've seen with THIS LIGHT do not seem to have any problem with that. this grow had some over watering/no instructions issues as stated w/ the rapid rooter that caused the cotyledons to stretch because they were planted early(I know I know dixie cups from now on).
we'll all find out in a short 3 months
