Hey
I like them but with a huge disclaimer.
Like with all HST it comes with risks.
If you so use them I suggest using for 3 or 4 days at a time. You want to remove the bends after they have caused stress and created a structure but BEFORE they cause harm to the plant.
I used on the top 4 nodes of each plant. The structure stayed and the plants have an awesome evenness to them. Like a big ball of green.
However I left them unattended, didn't check them twice daily, so by day 5 when I removed I lost 1 top and 2 lower sides.
Luckily off different plants and with training and topping I have recovered.
All in all I will use again. However I suggest using them earlier. From week 2 maybe. (I did week 4-5) as the stems are thinner and won't be as able to be pinched by the bends.
Also make sure you bend and flex the bends the opposite way before using. They have alot of give and you can make them a bit less severe of a bend. The issue seems to be the sharp edges trapping the stems as they grow thicker than the actual bends so using earlier would fix this issue.
They are looking very even, bareing in mind theres 3 different strains. The training has given some great uniformity.
Hope this helps. Any other questions tag me in
