veg for atleast 3-4 weeks then kick into flower, you can pull atleast 1 1/4 oz dry weight, but do yourself a favor and top it,. At week 2 of veg, cut the top of the shoot off leaving the previous 2 nodes, veg for 2 more weeks then top the new shoots leaving thier previous 2 nodes on each shoot, veg for 2 more weeks and you will now have 4 tops to your plant, do a scrog type setup to keep the shoots spread apart and you will pull 2 1/2 - 3 oz dry weight from a short bushy plant. Big Bang has big tops and it is impressive, I wish I took picks from my last grow, the tops were as big as 1liter soda bottles.
