In the current thread discussing the problems some indoor growers have with s/h one member stated he had about 10% plant loss in s/h and another member stated he thought that 10% plant loss was unacceptable. This makes me wonder what do people consider as an acceptable plant loss? Of coure no one likes losing plants and 100% is what we strive for. But, realistically, what percentage of loss should dictate changing growing methods, watering or fertilizing practices etc.? I wonder what commercial nurseries loss numbers are?
