sorry, that i didn't put the part about the light and the heating in the original post, but here we go:


the green house was one of the heated kind (with a heating cable running through it's bottom) and the whole system stood in a former bathroom that was kept at a certain temperature anyhow.

at the same time when cutting new clones, i always had some others that already rooted and were put in soil (at that time at least.. later i changed to a aeroflow system) and were about to being given away to friends or used by myself.. those were standing under 20 fluorescent lights (15 of them were 865's (that's 3-band and 6500 K colortemperature) and the other 5 840's (3-band, 4000 K))

i always put the greenhouse directly next to the other clones, so the lamps were not directly overhead, but about 15 inches away to the top-right, but this was an issue of lacking space
