    Default Home Made Grow Lights

    Due to lack of light at home resulting in leggy seedlings, For the last few weeks I have been thinking about making one of These

    with 1, maybe 2 of These.

    The time has now come to make a decision.............Do you think it is worth it?
    As always, your comments are appreciated.

    Yes, I think it's worth it. Those tubes are the same ones as those in the Growlight Garden thingy I just bought, and are supposed to last up to 10,000 hours, plus they're relatively inexpensive to run. After the last couple of years, I think anything that's cheap to run and brings the plants on quicker and more healthy is worth a go.

    Thanks Sarah, I was wondering if I would need then to add a reflector to the tubes. It's all new to me.

    The one I have has a white panel behind the bulbs to reflect light, but it only seems to be coated cardboard, nothing fancy.

    Thanks, Maybe white does not reflect intense heat like maybe foil would.

    Isn't white card a better reflector than foil? (bounces it in all directions, etc)

    You won't get intense heat with T5 tubes so that isn't an issue. WIth the T5's you can have the tubes very close to the plants without danger of scorching. I don't personally use a T5 growlamp system but many exhibitors do. (I have a 400w Sont agro lamp which I have virtually retired because of the cost of running it and an LED growlamp which I am still not convinced about). If you want to reflect as much light on to your plants as possible, Mylar sheeting is probably the best product. From memory, the best has a diamond profile. My growing space is in my shed. I have the roof covered with white conti-board and the grow box is surrounded with mirrors and mirror tiles.
