This one is from today (26 january)


Problem:
The problem is that they still don't start to flower and they are getting very big for the height available.
They should start flowering now because this is the time when plants start flowering in this hemisfere.
What do the experts recomend to do?
Thanks

You could put stakes in the ground and pull the plants over or use a wire tie to bend the tops down. If they haven't produced flowers then you could top them but if they'll be flowering soon might be a bit late to top them. I think if you bend them and tie them down the best you can you'll be cool.

I'm no expert only third year but just wait and it will flower very soon, I forced a few of mine to flower by putting them in a lightproof tent before the sun set and pulling them out after sunrise. It was just a experent but it worked. I would just give it a couple more weeks. Mine started flowering a bit late this year too. I have 3 that are not in flower yet. Southern Hemisphere in Australia.

Low stress train them. Bend them, tie them down.Put a net over them.

please dont make multiple threads in various subsections, i have merged your threads into one. good luck!

Tie them down and u know there probably wasting alot of energy trying to get more sunlight and thats why there stretching.

Cut them back. I go for the apple tree shape, works best for holding weight and getting light imo. If mine start to look like christmas trees I'll cut them right in the middle as far down as the side shoots.

Do you mean cutting the inferior side branches?
Mi problem is the top cola reaching the roof of the greenhouse.
