Would this light be suitable for starting seedlings? If so, what distance would be recommended?

That is what I use this light for and I keep it on a pully system and keep it 4 to 6 inches from the plants. Keep in mind it will only light a tray of about 15 to 20 seedlings.

This would be fine, may promote stronger stems. I would add full spectrum after one week or two, if your not planning on moving it to soil or hydro after propagation. You may place it as close as 5" just keep an eye on temp make sure it stays about 75 just warmer then normal veg room.

Depends on what kind of seedlings. Either way I have found that you must get them very close to the light for the first few days.

About five inches from side to side. The skimpy sides don't do a good job of reflecting. If you can find a hardware store or lumber yard that will cut flashing to length, buy five feet of a narrow width (3", or 4" cut in half lengthwise), and duct tape it on so that 1 1/2" extends below the sides. Or buy a better fixture. I've found two tube lights to be inadequate for seedlings, but if you can find a cheap, narrow fixture, you can buy two and join them together with a couple lengths of 1/8"x1/2" aluminum bar (across the top, pop riveted, careful when drilling into fixture). You'll still need additional reflectors on the sides of the joined fixtures. I made a four tube, four foot light for less than $30 this way.

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!

I agree with the previous answer, the light is minimal. If you had them on either side of you path and spaced pretty close, probably every foot or two you might have enough light. Cool idea, but no sure if these are the right choice.

These could very well work for that. This comes with a 150W flood bulb that will provide a lot of light coverage at that distance at a decent brightness. These lights are usually used in multiple sets to make more light or have colors in front of each to provide color effects on the same area. If you were unhappy with how wide it is, and you would not like to move it, try going to Home Depot in looking for a halogen Par38 bulb that is 90W and a spot, not a flood, coverage. This will give you a much narrower beam and more brightness at that distance in a much smaller area (less overall light, but more of it in a smaller place). Ultimately, the black metal part is just a bulb holder and a cord set to plug it in, and all of the lighting brightness and how narrow or wide it is is dependent on the bulb, which can be easily swapped out since it uses a standard size lightbulb thread. Just like buying a room lamp at a store, how the light acts is all about the bulb. The casing on this bulb is black and has a gel frame spot to suggest more of a usage for performance and entertainment. But at this price, it doesn't hurt to try one and see what you think. I happen to use these at one of the performance space I oversee. They use a set of 8 of these units, with the 90W bulbs that are spots, with 4 on either side of the room pointed across the stage evenly - the throw distance being 15-25'. They are hooked up to a dimmer panel for entertainment that can be controlled by an entertainment lighting console. This is a very cheap option to get started and go from here.

It depends on the lumen output of your bulb. Minimum amount of lighting needed is around 2000 lumens per square foot.Mid range is around 5000 lumens per square foot. Optimal is 7000-7500, or higher, lumens per square foot. 40,000 lumens would be mid range for that tent. I use a 400w HPS light in that exact tent and it does the job. Then there is a matter of wattage. Judging by your 300 w rating it may do the job. Take some time to do the math. More is better than less and your plants will tell you the same.

I've been using a grow light for seed starting for years. I used a make-shift grow light with this Hydrofarm unit and had good success. The key to successful seed starting if mildly warm bottom heat and constant minimum moisture to the growing medium. Don't overwater.

It all depends on how many your looking to grow and from what stage of growth. This light is perfect for seedlings, clones and small plants. It covers a 2*3 area, just remember that cfls need to be close to the plants to produce vigorous growth. I found that 6-10inches above the plants is the sweet spot for this light.. You can fit 6 decent size plants under it but its better for a tray of clones or seedlings....

I use this light to illuminate a 4'x4' tray. The plants on the very edges all lean inwards towards the center. I went to a different reflector, 24"x24" and this eliminated the plant lean. I think the reflector would be good for a 3'x3' grow at max. The ballast and bulbs are good though.

No this blub does not have enough light to do you any good. To set up starter plants you need at least 7-8 watts of power to give the seedling the energy they need. 15 watts would be better. Also I found this small blub heats up far too much for a LED. More than a 15 watt one I have. Remember you are trying to replace the sun's energy so the higher the watts the better the growth.

This light should be more than sufficient for your purposes. It is very bright and works quite well for plants. I no longer have an aquarium, but last spring I set it up for our garden starters; the plants under this light did much better than those under an ordinary full-spectrum light. I hope this helps.

Probably not, you will most likely need the LED indicated for plants, it has a different light spectrum

It includes one 54 watt high output T5 light bulb which is adequate for starting seeds, may not be enough for bonsai. Their high output LED grow lights may be better for continuous/long-term plant growth (also available on Amazon). You could always ask Dirt Genius, www.dirtgenius.com

I think this light is very bright, and would work. I use it for the inside of a chicken coop, and it has much more light than what I want for that purpose - I wish it wasn't so bright. Not sure how big your trees are, but this puts out quite a bit of light.

This light has those nm so it will help plants to grow. But it ready doesn't have enough wattage to cover enough area to feed the plant properly. I went up to a 7 watt bulb but it was still too low in wattage. You need at least 15 watts to get the proper color balance and cover most of the plant. like in my case grass seed for my cats in a planter. If you have several or a large plant you may need two 15 watt bulbs. Gives the whole plant better coverage.

You want the grow light as close to the plants as possible. Any more than a 6-12 inches away from the plant and it's not going to be very effective. While this grow light is surprisingly powerful for the price, it doesn't cover more than maybe 12 inches or so in diameter. I would use this for maybe a few basil plants or herbs, one head of lettuce, or a smaller pepper plant (e.g. jalapeno).

The light output is roughly that of a 30 to 40 watt bulb so it would not be bright. That said, I bet these would work great for landscaping. I used one for the balcony light and it works wonderfully - another lights up a silk tree in the corner and the effect is very cool. Too much exposure to the weather might not be too friendly for the bulb so keep that in mind. My first bulb, btw, has lasted over a year now.
