THat is correct...stick your finger in the soil to see if it is damp, if so do not water. If it is crusty and dry then water. Any time leaves look saggy use common sense to evaluate the situation. Go through a process of elimination when confronted with a problem.
Cool thx guys. LOL Next question. My 400watt hps decided not to turn on this morning. ballast still humms but makes buzzing noise & lamp tries to turn on but just won't.
