help with temperature please

well thats it, how much time before temperature problems manifest?? i just upped the plants a little bit, but dont wanna burn them =/

how close are they and what type of light you using?

hey!, they are about 14cm from the light, i followed the "hand" rule, but seriously... my hand can be almost "on" the light lol....

its a 70watts hps, any idea?

With a 70W HPS you can place your plants quite close to the light.

I run a 125W CFL (not as hot as HPS though) 10cm (3.9 inches) from my plants.
