I have a 20W halogen floodlight cast onto a Witch Hazel plant, and I'm wondering if the light output from the floodlight will somehow screw up the blooming of the shrub... not sure if the artificial incadescent light would in some way trick the bush into thinking it's day all the time? I *assume* UV light would be necessary to do this, but who knows...

I'm also planning to install more lighting in the Spring and don't want to mess up any of the other blooms (Rhodies, Azaleas, Hydrangeas, etc.) with my lighting schemes (note - the other lighting will all be tier-style, it's just the tall Witch Hazel that I will have the floodlight on).

distance from bulb to plant???

my gut tells me.. that if halogen was a good light to encourage growth ... then those of us who grow indoors under lights would use halogen instead of flourescent ... though i may be behind the curve on this ...

that said.. when i use light.. i set the lights within about 2 inches of the plant ..

i do know there are very high intensity lights that the hooch growers use.. that do not need to be that close to the plant..

but i would bet a buck that they arent 20 watts ... lol

my gut further tells me.. this shouldnt really be a variable in you mood lighting ... do what you want.. and be happy ... ignore this ...

you might ask in the landscape forum ...
