Low Stress Training in 12/12

Quick question, I have 2 plants that are vegging at the moment and I've been training them for almost 2 months. I'm going to be ready to switch em' to 12/12 in a few weeks.

My question is, When do I remove the Lacing that is holding em' back or do I just leave em' on the entire flower cycle?

All input is appreciated

Thanks for your help Riu, I really appreciate the mass amounts of replies

being sunday at 4:20 in the a.m. you may have to wait a little while for an answer. I hope/think you will get an answer from ppl that use this method, be patient. I did read somewhere about untying them, but I can't rmemeber when they said to do it. Did you try googling the info? it may help. Besides, you don't want someone telling you a b.s. answer, I've got a few min. I'll see if I can find what I read before.

You can still use LST in 12/12 - my advice would be to un-tie them to make sure you string is not being inbedded in your stems or branches - then re-tie them...

If/When your buds get big and heavy, you may want to tie them from above (if this is possible in your garden?)
