Pretty nice plants! They enjoyed the higher amounts of nuts, even though they showed a bit of Nitrogen toxicity, nothing serious, a bit of 'claw' on the new leaves, but they seem to handle it fine so far.
They probably tripled in size this week.
They got topped the second time this week.
They are bushy with thick branches. I hope they will pick up a bit more on hight the next week!
@shiwnouk,
Thank you! It’s not all as pro as I wish it was, but it works fine for now 😊
The vent is a UFO Ventilator 250 m3/h 100 mm. It looks very similar to the one you mentioned.
