Sinsimilla Finola females excl, being grown on my yard at lat 65 Finland.
The tallest females here are now standing beyond 2 mtr tall.
To remove the males is indeed a painstaking process that'll take about one month all together, but it was significantly more easy to do on the other side of the plot where the plants have been sown in more thinly.
There is always a risk that some retarded seeds will still pop up, and it has got my up most priority to keep soil surface free from obscuring weeds for inspection.
(In the upper right corner of the first pic, and the third and last pic as well, there's also 'broad bean' to notice. We had a rat infestation this year that killed off many of the beans, but luckily they did not seem to care about the hemp at all. The beans are not much to see on the pictures in here, but on places where rats did not bother digging em up, the hemp seems taking a huge advantage of their presence)
This picture was made on 11-7 and it'll show off the side of the plot that was being sown in more thinly >
