Huuuuuggeee fan of white crack! I have about 5 of em left and its soo hard to hold on to em.. That and Beary White have been my favorites so far.. And what I've learned about roots on autos so far is that they actually do have something to do with triggering the flowering process. Roots seem to know when they can no longer grown outward. I think that once they start to over lap each other, they go into flower. Smaller pots finish quicker. Bigger pots take longer. That is fact!! Root tips are like human brains! Amazing little suckers!
