    Thanks, Jon, I am supposed to be selling flasks but can't quite get going on it. I know how to price plants, but flasks are another thing. Some of those are flasks I am doing for others, but most are mine. What you are seeing is just a little over half of what I have.:eek:

    I'm pretty sure I read once, on an internet forum so it has to be true...that things like mirrors and mylar and silverish colors tend to scatter the reflected light. Whereas white tends to reflect more usable light back towards the plants. Maybe it is true?

    @Alexis - you took the words straight out of my mouth. Marni, what an inspiration. Personally this is important; it reminds me that although I'll have my career, I am fortunate to have a hobby that I love...Your setup reminds me there are endless directions to take my hobby, and that is a comforting thought.


    Funny, I've come across the exact some conversation on a forum :rolleyes:

    I think that is true, but I suppose the benefit (or lack thereof) will depend upon your application.

    For walls, especially north walls in greenhouses that would otherwise just "absorb" incident light, and for light fixtures intended to provide visual lighting, the scattering of a white surface is a benefit. For a plant light, however, the goal is to direct as much of the bulb's output to the plant, so a mirror-like surface shaped to take the light from the back side of the bulb and redirect it to the plant, rather than scattering it in all directions, would have the advantage.

    Ray is right that these really focus the light on the shelf below so it is much brighter. Holding mylar up on the side just didn't do the same thing. I did find that to spread the light for a shelf 24" wide I had increase the distance between the shelves from what I was expecting or I had low light at the edges. I am still totally happy with them.

    Chris, I'm not much of a bulbo grower so the only thing I have germinated is Bulbo elisae x self. I tried B tingabarium outcross but no germination. I have pods on a couple of others, but they aren't ready to harvest.
