Hello, the humidity was always too high during the growing period in the hoop house, which should have caused many diseases, especially botrytis.
Would you pay attention to the method of vegetable’s early forcing in hoop? To cover the whole ground in the hoop with mulching film, and let the drip pipe under the film. When the buds of the peonies break the ground, we pull out the buds from the film. The humidity in the hoop could be down a lot.
As to the 1g active ingredient of GA3, would you supply a photo about its instruction? I plan to try in my own nursery, and there are some details which I’m not sure…
Thanks a lot for your sharing!!
