Tasty buds! I have grown a number of GreenCrack from my west coast Canadian seed supplier. They grow strong and tall. Best to top the plant while it is still young. Wait for 6 nodes to grow and top down to the third. Remove the lower nodes so only your third node growing tips remain. Weeks later, but before switching to 12/12, remove all the lower scraggy branches. Big, tasty buds. Yum!
