Hi, I'm new here. I hope I'm posting this question in the best location.
I live in the far north of VT, I've had some success with starting my seedlings on my windowsill but I'd really like to get them a more robust and healthy start. My usual windowsill has a 12" wide ledge and fits two standard garden flats side by side; my idea is to build a shelf that will fit there so I can have two tiers of flats (4 total). I decided to take a chance on ordering these lights: https://www.amazon.com/gp/product/B01LO55HJI/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I'm not having a lot of luck finding information about using these, I think most people use them for growing marijuana so a lot of what is written is not applicable to me (trying to grow in enclosed spaces, trying to grow plants to maturity, etc).
So here are my questions:
1) I bought 2 3m sections, my shelf is going to be approximately 12" deep by 45" wide. I figure I will snake them back and forth, and not connect them in any way but plug them in separately. Will this be enough light? Too much?
2) I saw somewhere that someone attached these to an aluminum bar to dissipate the heat. I thought one of the advantages of LED is that the don't generate much heat? Do I really need to do this?
3) Any other thoughts or warnings for me?
Thanks in advance!
