So you keep your compact fluorescent lights on 24/7? Combined with natural light Maurice?

So you keep your compact fluorescent lights on 24/7? Combined with natural light Maurice?

I did for those seeds and for various tests.
I hope to do other tests this year and those plants will not have access to any natural light - no doubt I will find out how well they do under those conditions. Those test plants will not be seedlings.

When I grew seedlings under fluorescent lights, I had the ability on my shelving unit to lower or raise the shelves. I started off with the lights about 8" from the cups with seeds sowed and then adjusted the shelves down (away from the lights) as they developed and grew. I also turned my lights off at night .... I tried to turn them on at sunrise and off at sunset, but that was not always the case. I watered them only when the top 1" of soil was dry, so about once (maybe twice) a week. And I used the hydrogen peroxide drops with every watering. They have a bad tendency to develop damping off and root rot if I watered them too much in colder temps. The room stayed around 55-65 degrees because of the outside weather temperatures. Seedlings developed just fine (perhaps slower than if temps had been warmer).

I know with t5 you can lower the lights to maybe 2" away from the pots cause of barely any heat produced by the t5 light. Not sure how sensitive daylily seedlings are.

I think my lights are T7 and did get a bit warm, which didn't faze my seedlings as long as I didn't let the soil dry out completely. I also grew many on my south window sill behind sheer curtains (to block some of the intense sun rays) and they loved it there.
