STRAIN for AUTUMN GREENHOUSE GROW EXPERIMENT

Hi @Dingle_Dangle. I have just started one as well which I am using gorilla cookies auto. From the look of your climate charts I see that you are not going to have very 'extreme temperatures' in sept/oct. I am thinking I will go well into November with mine, as I have found the autos to go a little slower in the shoulder season. Adding thermal mass (containers of water) is really important to help retain the heat overnight. But having a contingency plan (heater) is also important in case of unseasonably cold weather. I think one of the main considerations will be picking a strain that is tolerant of a few cold nights and changing humidity. I grew a Zkittlez auto in my greenhouse this spring, and it worked quite well, and has a very low smell if that is of a concern. I have also done a shoulder season White Widow Auto as well which is pretty tolerant. Another consideration is flowering time. Selecting faster auto genetics is important, as you will lose some intensity from the sun as winter sets in, so the quicker you go get to harvest the better. It may be worthwhile sending this question to your favorite seedbanks/breeders and see what they suggest. Good luck on your grow, its cool to see people fighting back against seasonal norms!
