- More light = More bud.
- Topping, LST, FIM, Super Cropping.
- Using best nutrients you can lay your hands on - i,.e CANNA nutes and additives.
- Keeping temps and rH (relative humidity) low enough.
- Growing hydro (or better yet, Aeroponically) will speed up the flowering process, resulting in as much, if not more bud, in less time.
- Getting to know the strain you're growing as good as possible so you can perfect it's nutrient schedule and pH levels.
- Getting your growing environment as best suited to your strain as you can.
- Obviously growing a strain known for heavy production would help - althogh I personally don't like commercial strains as a general rule, they are bred for production!
- Various additives could help, but I'm not a big fan of additives other than the ones incorporated into the CANNA feeding schedule.
Hope some of this stuff helps. Cheers.
