Growing Begonias indooors
I was a member of GW years ago, but got busy and drifted to other sites. I have been an African Violet and gesneriads grower, for several years and have recently been bitten by the Begonia bug. I have lots of light stands and every sort of fluorescent fixture, from 2 tube T12s to 6 tube T8s.
I have acquired over 70 varieties and species, within the last 2 months and intend to grow them permanently, under lights, though some, like B. luxurians, will have to occupy the sunny office, when it gets too tall.
I intended to wick water them all, like I do my violets and gesneriads, and created a mix of orchid bark, leca stones, chopped long fibered sphagnum, perlite, and a bit of my coir/peat based violet wicking mix. I have had a few rot on me, but the majority are doing well and I discovered I had over potted the ones that rotted or used a heavier mix, than I am using now.
I don't see a lot of information about growing under lights or wicking begonias. I have heard many say that the rexes need the most light. I am so far growing my rexes under 4 or 6 tube T8s and most of the canes and species are under 2 tubes. I have a lot of moving around and reconfiguring of lights to get everybody, where I want them, but I am wondering what experience others have growing begonias indoors, permanently. I hope to begin showing them and hybridizing, the way I have with my violets.
Thanks in advance and it's nice to be among you.
