i have 13 plants outdoor in oregon in a great spot and they are doing well and are about week 4-5 into flower. The Weather is changing FAST the nights here are getting really cold and its supposed to rain for 6 days straight. should i go out and make little teepees of clear plastic around them?.....I am going to mulch them so the roots dont freeze also......what else are good options of saving my crop? i would really hate to see these girls go to waste......my only concern about the plastic teepees is their visibility from the air........lease leave me some feedback!
