Yeah unfortunately I'm outside and it's been a very rainy season. I have one started in side right now a sugar black rose auto.
Best of luck with this one!
Without knowing your night temps its a shot in the dark. If your soil has been wet constantly then thats another thing that stalled growth. Your autos roots are probably water logged. Im surprised theyre still alive. Got to love that ruderalis trait. Only media Ive used that can be wet almost all the time is coco. Next time start them indoors. Night temps never lower than 65 and never over 95. When the autos are about one feet tall move them outside 3 hours a day in direct sunlight and bring them back indoors. Do this for about a week (this hardens them off for outdoor growing/your environment) and after that you can leave them outdoors.
I too start in my "grow shed". Temp control and 18/6 lights. Funny, also grow to about a foot high before going outside. I will aclimate a little too.
My summer lows are usually in the low 50s at night exept for a brief few weeks mid summer, then it's 55 at night..so not ideal for veg, but works.
* This gets me thinking about the right amount of indoor light before moving outside?
Should one maximize light to maximize growth indoors? Or should one match the light to what the plant will experience outside?
I'm at 18 hours of light inside and move out into 15 to 17 hours of light. (may/june)
