I've also learned from this forum that light pollution can be a big deal for outside plants. Is there a security light or something around that might not let the plant get the darkness it needs?

As others have said, if you give it 12 hours of dark, however you do it, the plants will start to form flowers if it's a photoperiod strain.

Hmm, interesting ill check that out. Also to note, he done a couple of autos in there too and they didn't really develop properly either. Bud sites, but didn't turn into real buds. There is some perspex for the windows, maybe that blocks out some of the spectrum or something, any thoughts?

Use photographic green filter paper or a green bulb ,if lights on your land .

If you think it's something with the greenhouse itself, the only thing I could think to confirm would be to get some testing equipment... Do other plants grow well in it?

Not sure about other plants, its all cannabis in there! See pic of full plant, seems reasonably healthy but just won't do it.

For testing you mean a light meter or something?
I think a new greenhouse with a better aspect is required for next year.

The strain is strawberry amnesia if that has any bearings on it.

Plant seems fine to me. It's super weird that autos didn't go right either, makes me think it is something with the light possibly.

And yeah, a PAR meter so you can see what kind of light is getting through. I am not well-informed enough to know if this reading alone would tell you all you needed to know about what spectrum is getting through for your plants, though.

Was hoping other plants were in there so I'd know if it was just a cannabis issue, or a green house issue.

Ok thanks. Must be the setup really I guess, various strsins, autos and photos and none of them have worked out. Must change something for next year for sure.

The auto was weird too. Gorilla glue, it had super dark green leaves all the way through, never looked like it was ageing and the buds just didn't fill out.

Its like a greenhouse from the twilight zone!!
