well my plants are 18 inches and del said about an ounce a plant cuz i started late in the season but if urs are that tall i think they will probably produce 2.5 - 4 per plant thats just an estimate though . And to get the most bud u shud make sure your plant is getting the right nutes (15-30-15 for flowering) and sunlight. And to get even more bud you can reflower them but that wont work if u cant bring your plants indoors i dont think just because of winter. aight pce
