As a matter of interest:
For the past two years I have hung two extremely overgrown 10" stock plant Zygo...baskets
on the truss of an unshaded greenhouse with 6 year old fibreglass panels all summer and fall
with no apparent damage but extremely heavy flowering results. Naturally shortening days in a
heated -60F nights-ghse results in flowering end of November near Vancouver,BC.
