I am growing a Northern Light auto from Nirvana. 400watt HPS 3 gallon pot. It is almost 10 weeks old and Iwas forced to top the plant becase a fan fell on it and broke the stem. this happened at 4 weeks into the grow. Now I have a nice plant that has 2 nice main colas going but all the fan eafs...
place the paper towel in a ziplock (open) put on a plate and place it on top of your ballast, that will give off enough heat to pop those suckers right open. good luck and happy growing.
