This is super simple/easy, but it makes your plants take a few weeks longer to grow ie start sooner.
1. As little seedlings in peat pods, point a fan directly at them, so the blow over completely. As soon as they start to stand back up? (A couple days) turn them around so they’ve blown over, again. Keep spinning your plants and let the wind knock them over, until it can’t do it anymore. Do this to them as babies, and instead of a finger thick stalk, it will prompt them to grow a main stalk as thick as your wrist. Which not only makes them sturdy as hell, but also creates a very wide highway fo water/nutrients = lots and lots of fruit.
2. As soon as they’re about a foot tall, “pinch the tops”. Literally, pinch the tops off, right by a leaf, if possible. Generally about 1cm or less down. When it grows again, instead of 1 stalk, it will fork into 2. When it’s gone about 6 inches, do it again to both stalks. And then all 4. Stop there, or keep going to 8 or 16. Depends how BUSHY you want your plant, and how much time you have. Each pinch makes it take about a week longer than you would without pinching.
