Extending tomato height

There is never a moment that you can’t keep a close eye on tomatoes. Pinching armpits, Tying in growth, stopping height by pinching tips. Removing or reducing leaves for sunshine, controlling temperature water and air flow, watching out for overgrowth, new stems on the ends of flowers seems common in my greenhouses, keeping a close eye on disease. I spend at least 3-4 hours a week on tomatoes alone. Thank heavens I don’t put a value on my garden time.
