Howdy Sammy, I started using a wire chain (links look like figure '8') to hold up my lamps. Each link was approximately 3/8" long and was secured to a cup hook in the support beam (2" x 4" across the ceiling). I adjusted the height by changing the link 'in the hook' up or down as needed. This called for a lot of counting links (to keep things level) and a sure grip on the chain to prevent falling lamps. I have changed to using the 'rope ratchets' and the are much easier to use. The only problem with the ratchets is when the lamps are near the top of my grow space, it is a little awkward to reach around the lamps to get to the ratchet for adjustments.
Good luck with Your grow.
