yea I agree tieing down is far better than tipping, or fimming. Mainly because your not stressing the plant or slowing maybe even stopping its growth
Your not stopping its growth at all tipping/topping /pinching/fimming anything actually causing damage to the plant is going to make the plant stop, repair the damage, then continue growing or at least slow growth whilst repairing. im no botonist but thats my understanding.
Of course for you THwizH2O in your airo tubes id actually start bending tieing them over once they had grown 1 inch after rooting basically in a bigger system with more plants your just really wanting to create 4 to 6 decent main stems before switching to 12/12 the height can be keept to 1 to 1.5 feet.
You dont need to tie of course just pressing lightly on the daily, bending them over. you could even consider a say bending a plant 202 style lol and create a scrog frame above your tubes and bend under the frame creating a canopy that way. Id normal bend mine over much earlier but these are in a shed and i wish to scrog without a screen tieing and bending down to fill my available space with the limited plants i have.
By the way you asked what strain they are the white rhinos ive moved them into a shed/greenhouse type thing more concelled with enough light for good growth.
Another quick tip to avoid breakages is basically get a air pressure spray gun use water with wetting agent spray your plants i find wet water logged leaf and stems often bend easier
@ice 2000 does it make that much of a difference im doing it
:P if i thought it didnt i certainly wouldnt be doing it lol ill post more pics in the comming weeks of its progress.
