In the mean time you might want to get a cheap heating pad instead so you can set the dail and keep it constant since you are throwing your money away on hydro costs using your hps, in the long run the heating pad would save you money. As for the temp spike just ride it out and make sure it doesn't happen again, that's all you can do.
I only have an HPS. I know it's not the ideal and that I should have more of the blueish spectrum via Metal Halide or CFLs but I had to budget a bit and am under the impression this is acceptable enough.

Maybe should I put them by the window? Sort of ease them into the light? I have a discreet place to do that.
Is it the norm to put them under the light at this stage? I couldn't quite work out if I should wait for leaves to appear or if they appear once they are under light.

It's not costing me much in power ("hydro", I had to think what you meant and then I saw you were from Canada and realised) to have the HPS turn on for a short time. My costs will run about 20p per day when I'm on 18/6 and I don't think I'll find a heating pad for that little. It's just an additional cost and I'd like to avoid that when possible.

Thanks for your response.
PlainJane Reviewed by PlainJane on . Problem mechanical timers (not shutting off) & lighting on seedlings Q? I've now had two timers "go bad" on me. This is a problem because obviously I can't be constantly worrying if my shit is working. :mad: I got a mechanical electric timer (you know, the push the little knobby bits up or down on a dial kind) and it worked for a day but then decided it didn't want to go off when it was in the off section. Nothing would override that. Now I have a second one (different brand) which is doing the same thing, except if you push the override button it does shut Rating: 5
