UV lamps for azalea
I recently (yesterday) bought an azalea (Rhododendron simsii). I did my homework and read that these need some sunlight during the winter (along with a cold temperature) in order to bloom.
In winter, there will of course be less sunlight than in summer and other seasons in general. This is why I got the idea of buying a UV lamp for it.
My question is: do any of you have experience with UV lamps, positive or negative? If positive, which one would you recommend? (since I'm 19 and still live with my parents i can spend around 150 euros)
Thank you in advance!
