ok i have this water bed heater if i set them on the heater pad would that have any type of effect im a lil late like a week on the whole plantin thing but i got every thing else so i guess my question is is it all right to use the heating pad and if so what degrees should i set it on and my buddy said i should use some miracle grow shit and all this extra growing stuff would it kill them if i used it i already checked to see what the nitrogen levels are and nitrogen is higher on all the boxes what should i use??
