The longer the veg the larger the plant, The larger the plant the larger the yield. your plant will increase about 2-3 times in size when in flowering. Make sure you have space for it. To increase bud size, use bloom nutes and molasas. make sure you watch your PH.

molasas like that sticky shit ive got some miricle grow bloom stuff
