warm white bulbs are not ideal for vegetative, but they would work to some extent.

get at leat 2 23w coolwhite/daylight cfls over it, and find some way to prop it up until it can strenghten.

the fact its sativa really shouldnt affect the stem strenght, its usually due to too little light at too far away, causing the plant to stretch to far to support itself
hybridlove420 Reviewed by hybridlove420 on . Help my 2 week plant has fallen over! I have flushed out my plants because of I burnt my plants. Now my pride and joy has fallen to the side. I don't know if it's stem rot or heat stress. So i have tied a string loosely with some slack to straighten it up. Why is the stem failing to hold up the plant?:stoned: Rating: 5
