Hey man, I would really like to use those PL-L's and I will try to use them in the future, however I've already got my lights so I will just have to work with what I got, I can't really afford more lights right now. When it comes to time to be needing new lights I will get some PL-L's. I need to see if someone wants to buy the bulbs I currently have first then I can buy something else..
I really just need to know the best height and if it's better to make each grow chamber 30cm in width rather than different sizes. And then I can start upgrading my lights and airflow systems.
