Thanks for the pointers.Cold temps drive transpiration rates down and tend to stall flowering.
Also haze varieties require a lot of sun to develop to their full expression
Small calyxes are from low light/low temps usually unless genetic
10-15c for more than a few days will stunt growth especially if the pots/roots are even lower.
If you can make their feet(roots,pots) a bit warmer they should coup with the cold better.
Yeah I gather that you do your best at the conditions at hand, not easy with that kind of cold around indeed..Thanks for the pointers.
Though, being a guerilla grow, in a nation that has some pretty N@zi drug laws, there's only so much I can do.
If you go back through last season of this grow, you'll see that they mature okay in the winter here.
In fact, these girls in the pics above are doing fine in the weather.
If they are in pots id recommend isolating the pots somehow to retain as much heat as possible.Root temps will just be ambient temps, from about 15C to 20C these days.
Any practical advice for warming root temps in a guerilla grow like this?
It's not like I can run a heating mat out there for them!
