I'm wondering why you would be raising plants up in the first case? You may want to raise the light. What you may want to consider purchasing (assumming it works for your grow area) some retractable chords that you connect to your light. That's what these things are for and you can easily find them for under $20. Good luck on your grow. Peace
I'm running a perpetual grow and I have tall plants mixed in with small ones. I want to lift the small ones up towards the light. I'm using milk crates to get a good chunk of the way there but need some fine tuning.
This is the only product I've found but the guy is asking crazy money for it.
