Can you grow seedlings with this light? If so, what distance would you recommend?

We have had very good luck growing seedlings with this light, have it set up about 2 feet above pots.

Hi! I purchased the 4 bulb fixture last winter. I had at least 6 trays of seedlings under the lights and they all popped up beautifully! Every couple of days I rotated the trays which helped. I,too, was trying to be frugal. Don't think you'll be disappointed. Good luck!

Depends on what and how much you're trying to grow. For one plant this is great, as the number of plants increase you will eventually need more lights.

Generally yes, although i guess it depends what you are growing. Personally i switch to t5 bulbs that are between 30,000 k - 35,000 k. The lights it comes with are good for vegetative growth.

If your hood is open and not a tube you could do that BUT cooling the light allies you to keep light at a closer level to plants, more lumens equals less stretch and more growth, also add a carbon filter or it will reek

They are not made to be used specifically as grow lights or they would be packaged differently. They might help but I don't know for sure.

Doubtful that it will work see wikipedia http://en.wikipedia.org/wiki/Grow_light. These lights do not have a multiple wide wavelengths. Typically these can be bought as a warm white more like a incandescent light bulb or cool white like an office environment. See color chart http://www.theledlight.com/color_chart.html These Led lights are around 3000K they do not have the lower wavelengths that the sun provides.

No. You would need significantly more light. I would suggest (2) 4-foot bulbs at the very minimum...

I don't , it has more to do with the distance the light is from the top if the plant, the amount of light you provide the plants and the age and size of the plants. I us as white a light as I can and have great results!! Control the distance and you'll do great!

I'm running it in a 90g saltwater fish only. light output is fantastic. But I don't know about grow capability. My local store is selling this for $350.

You can use it, but without a reflector such as: Hydrofarm FLCDG125D Fluorowing Compact Fluorescent System (bulb that comes with the hood is for vegetative stage, colder blue spectrum) much of the light will not be directed towards the tomato plants. Use the warm bulb for the flower and fruiting stages. Found this lamp to be of some use for supplemental fill in areas not well lit by the primary light source. Serious (small 4'x4' up to 6'x6') greenhouse vegetable growers are better off with: http://www.htgsupply.com/Product-Digital-Greenhouse-%20600w-HPS-Grow-Light ,use the standard 92,000 lumens bulb that comes with it for flowering and purchase the GrowBright 600w MH Conversion Bulb (72,000 lumens) ($44.00) for vegetative growth.

Look for a compact flourescent bulb that is in the 6500k spectrum which is best for plant growth. Something like the Zoo Med UltraSun Daylight Compact Flourescent sold on amazon for about 8 bucks.

If you have leggy seedlings, they are not getting enough light. Make sure the seedlings are close to the light (an inch or two away) and keep the light on 12 - 14 hours per day. Adjust the light as necessary as seedlings grow.

It probably can be used as a grow light because it's a full spectrum light. So it has to have the necessary rays, but I would strongly consider a " grow light " .

No. The spectrum and intensity are very much not sufficient for growing even low light plants.

I use a 6500K bulb and I find it works well. However, I also rotate my seedlings (flowers, fruits, and vegetables) into the sunlight. It really depends on the light color, the reflector, and the output.

It can certainly be done. An issue to be faced is the differing distances these two light types require from the plants. HPS generates a great deal of heat and, in most cases, will need to be several feet from the top of the canopy whereas these LEDs will lose effectiveness over that kind of distance.
