Can I grow plants in my tank with these lights?

We don't have a hood on my 50 gallon my dad is going to cut a couple pieces of plexiglass to fit but my lighting for that tank is this



It's three LED "mini floods" according to my Dad. They look just like the old mini floods we had in there but once we got the tank up there and we started leaving the light on during the day he switched to these to save on the power bill.
So can we grow plants with those? If so what kinds? If not what bulbs could I put in there so we can grow plants?

I don't think plants would benefit from those LEDs. You can put a "daylight" 6500k CFL bulb in though.

I think that's what I have in my vanity lights. I'll have to find the box maybe I can just switch two out.

Is it an open top tank? I'm not quite sure if the distance between the plants and lights makes any different at all. But it's best to have no glass or plastic barrier between the lights and plants.

Uhm it's probably a good three feet. I wanted to get covers because we are evaporating about 10 gallons of water per week right now.

I think those lights are too far from the substrate to work, besides being the wrong kind. PAR levels decrease with distance from the light source.

Maybe you could do some kind metal fixture, suspended by wire from the ceiling, to get the lights closer to the top of the tank. Have the lights drop down to be 6 to 8 inches from the top of the tank - suspended right above . It looks just as nice like this and with the 6500 or higher CFL bulbs, your plants might be ok.

Or just a couple clamp lights from Home Depot with CFLs.

I have to differ w/ Shannon. I have 2XT5HO lights about 3 inches from the top of my tank w/ a glass canopy to stop jumpers and reduce evap. There is nothing wrong with the glass or plexiglass (Lexan) on top of a tank as long as it is kept clean. It just requires a wipe down at each WC.

Glass is not a bad thing. Yes there is some energy lost to the glass 10 to 20% depending on thickness and type of glass. By far the biggest lose is the build up that takes place on the glass.
