Thanks for the feedback, guys! The chains on the framed panel is just a temporary solution, and will be changed for individual ratchets on each corner like you suggested. The plants were thrown into flower early, so they haven`t really grown tall enough for this to be a problem. Hopefully this will change soon
I think the filter is made by Prima Klima. I'm not sure though, as I got it from a friend who never got around to use it. It is rated for 1000m3 / hour, while my fan is rated for 555m3 / hour, so it`s a bit overkill.
Here's a few pics of the lights in action:
My main vegging space, 50x50 cm, running a 6000K china cob with 1 or 2 x 50w drivers depending on plant height and room temperature.
Mothers and small plants. One 3000K 100W china cob running at 50W, one 6500K 50W china cob running at 25W. The last lamp is also used for rooting clones
