Sativa with limited space help!

I have a 150w cooled cabinet in the closet with about 5x4x5 dimensions... the 3 females are 3 weeks in almost and are budding well, just my plants are SATIVA which are getting very tall and one is growing pretty dam close to the light and I have no more room to lift the light. I dont know what to do... all help is appreciated thanks.

Have you tried LST?

No i have not, i dont want to top it if i dont have to. its already been budding for a few weeks. So what do I do just tied it off to the side away from the light?

could also try super cropping.

yep thats what i would do.

What is supercropping? explain please

super cropping is where u bend the branches so the tops are no longer the high point of the plant. id just tie her up tho
