Containing light from filtering out

Posted by obrionusa 5 (My Page) on

I'm using shop lights to start to grow my seedlings and was wanting to contain the light. Something to go from the light down to the plant trays at an angle. This would keep the light from filtering out on the sides. I would keep the ends open with a small fan running. First thought was foil, but that is too flimsy. Then I thought maybe some alumium insulation board. Any ideas?

Shop lights or fluorescent lights in general are minimal for a light source and will need to be kept about 2 inches above the seedlings. I don't see a problem with light loss in such a small space. Al

Use one of the reflective emergency blankets you can often find in the camping section of sporting goods stores.

I had just posted some pictures of my set-up in a related thread below (use the link below to view it). This uses the reflective foam board insulation, as I wanted the double-bonus of hopefully containing a little more heat from the bulbs. (And according to the helpful people on this forum, they don't believe it will go up in flames, LOL)
