Color of light for gloxinias to bloom???
We're in a house now where the sun only comes into the plant stand area in
the winter. So 6 months a year they depend only on the grow light above. I just got a nice new fixture with 3 T8 32 watt tubes instead of the two 40 watt T12's that used to be there. They even have a polished mirror reflector, so they put down even more light. But the tubes I got with them are purplish grow light tubes and the gloxinias are forming buds now but then they shrivel away and don't bloom. I think someone here awhile back was saying that these kinds of plants need yellow to bloom? Should I replace one ( or two? ) of the grow lights with a T8 warm white, that has yellow? -- - Mama Bear -- Posted via a free Usenet account from http://www.teranews.com |

I see this sort of thing on my gloxinias that are outside in natural light so
I don't think it is related to the amount of yellow in the light. I think the shriveling is caused by heat and/or low humidity. I have also observed that there seems to be a critical period during the beginning of bud development when the slightest lack of water will ruin the flower buds. Once the buds get to be the size of a pea they seem to be somewhat resistant to my poor watering. --beeky Mama Bear wrote: We're in a house now where the sun only comes into the plant stand area in the winter.
