Hardening of

[pipefitter508]

I buy all my garden supplies from a farm near by they have 9
Greenhouse were they grow thousands of tomato plants to sell
So I asked about hardening off so many an I was told what they do is
With hold watering till they wilt then water this hardens them off they also use this method when growing the seedlings instead of grow lights this prevents them from stretching
Has anyone here heard of or used this method
