In an extension article on Colorado Potato Beetles it stated “ You should remove row covers when temperatures and humidity increase, as it will promote plant disease.” This may seem obvious, but 1) increased humidity and temps relative to what? Is there a certain heat index to judge it by? 2) if and when those levels drop, I presume you can add the covers again?
Thank you!!
