light levels in dry winter rest...does it matter?

[beaniebeagle]

so far i only have an overhead MH light. I want more blooms out of my winter rest dendros to bloom (aphyllum, pendulum, nobile, anosum etc)

does the amount of light that falls on the dormant canes effect how many blooms you get? I don't get as many as I like. With the overhead light, the tops obviously get more light, which seem to get more blooms than the bottoms.

does even lighting on the cane help with more blooms? If so, i would lay the plants on their sides or get a light pointed horizontally

I hope this makes sense
