Now it just a question of moving the wire pins out every day, keeping the side branches flat in order to spread the tops apart so they have room in flower.
You can see in the day 33 pictures how, if you pin the branches down in the morning, the tops turn up during the day and by evening are growing vertically again. Pretty amazing.
By day 35, I have stopped training the plants and am letting them grow upwards, ready for flipping to flower. Hopefully they will need only one more week.
@Godesskat, Thank you mate - at the risk of jinxing the grow, I'm fairly confident this will be my best ever. These plants are just so full of life, it's quite a joy to see.
