    I ordered a T12 7000k today cost will be around $7. The one 10,000K on my lettuce side is blinking as if it is going bad.

    I have used 4100K in the past and it worked VERY well. My plants always grew like crazy!

    Re: Grow Lights

    Hi all
    Excuse me for hijacking this thread but it seems to be where I could get some decent advice.
    I'm starting from scratch & got hold of a insulated truck box. 6.5" wide x 6.5" high x 13" long it seems to keep temps constant I want to start a mini setup inside it to prove a point that you can feed yourself & others indoors if I close the door it is pitch black inside.
    What would the ideal lighting wattages & positioning be to illuminate the room to grow your average veggies & house tilapia inside it ?
    Please keep in mind that I have to do this on a very tight budget.

    Re: Grow Lights

    well.. i'll say that it's going to depend.. t8 lights are 32 watts, i have 3 pairs over 1 pair of barrel growbeds, and get very nice green growth.
    water pumps for smaller systems are pretty low wattage, i think my original pump is around 35 watts and pumps over 100gal/hr at a decent head..
    you want to turn the volume of water in your fishtank over at least 1x per hour..
    so now get out and find some fish tanks and growbeds..

    Re: Grow Lights

    Thanks Keith
    I got 3 x 130 gal tanks against 1 wall inside & 2 x 400 gal tanks outside sofar. As for grow beds I'm still stuck I think Im going to try differnt types of beds on each tank.
    The other wall I have a bunch of various sized glass tanks for breeding tilapia & playing with guppies & killies.
    Its still very experimental but I'm getting there
