Too much time under fluorescents?

Posted by phoam (My Page) on

Anyone got good advice on how to determine when a plant is near its limit on time under your average fluorecent lights? (specifically, 2-bulb T8 32W 5000K)

Started some tomato and cucumber seeds (receiving 24hours of light per day), that I will be transplanting to a MH+HPS setting, and want to avoid leaving them under the fluorescents too long - but want to make sure they're ready for the MH bulb.

Addendum: average environmental conditions are around 73deg, 44% humidity. one or two days saw a max of 85 degrees. and a couple of days saw a min in the low 60's. the lowest humidity has been 33%, max around 50%.

I would say energy cost would be the only limiting factor for vegetables under fluorescents. Vegetables like much light.

Thanks. Any cues for making the move over to the MH light?

Once they reach about 12".
