i'm unsure this is the right site to ask this question, but my grow lights are not working. I have an outflowering plant which i give 21hrs light 3 dark. After the last dark period the lights won't turn on. The ballast is still running(well the fan turns on) and i even changed out the lights to make sure it didn't die on me.....has anyone ever had this problem? i check all the outlets to make sure it is plugged in and they are. any help would be appriciated. thank you

Please advise if the four T12 fluorescent light bulbs by Sylvania Grolux (two of them are 30 watts and two are 40 watts and 48 inches long) I have are adequate for seedling and vegetative growth phase of 25 seedlings?

For you to have a better idea, my grow area is 1meter by 1meter. I figured that I will be left with 9-10 female plants (with God's grace!), which should do o.k in a space 1 meter by 1 meter.

I am considering using fluorescent bulbs instead of the 600 watt hps light that I have because they run cooler and I don't need to have the a/c crankin 18 hrs a day for the 6 weeks of veg growth. Do u recommend this or am I better off using the 600 watt hps light?

God Bless!

Thats enough to veg that area, except you won't really be able to fit the light in there well.. And I think its gonna get awfully crowded in there with 25 unless you're going for a really fast flip to 12/12..

Plants cannot be disturbed during sleeping hours at all and especailly with red spectrum, it messes with the photosynthesist.
