i have seedlings that are about a week old and seem to be doing fine. One problem though, the stems grew to about 5" and now they are starting to fall over. They have 2 sets of healthy leaves that seem to heavy for the stems. im using 24 hrs flourecent lighting with the light about 1' over head and watering about 16 oz. of water for 40 of them. i gently tied them up to a support rod for the time being. they are kick ass strans so id be very dissapointed if they turned for the worse. is there something im doing wrong or is there anything i can do to help them?
