I have rocks in the bottom of the cups yes, maybe 1" worth of rocks. I will transplant these guys into larger containers when I get home which is just a soil and perlite mix. Now your telling me to run about 65 degreeS? I thought seedlings enjoyed 70-80? least thats what I have been reading? When should I move the lights closer? They don't seem to be stretching by all means. Can you tell me as to why I cannot use distilled water for my seedlings as that is what I have been using since day 1? lol
