Ive got a problem.......

i have made the mistake of vegin my plants for to long. they are to to tall for my grow space. should i cut them down (although i dont want to or bend them over. any1 got any advice on wat to do and how to do it

You can top them and clone the top. You can also bend them if the stems are still green and not woody. Or build a bigger cab. I think bending them is your best option.

to bend do i just tie some string round the stem and attach it to something on the floor?

Go to the home page and look in faq. It has a section on topping vs tieing and training.
