I have searched online to find the appropriate light bulbs for my seedlings, last year i got the wrong bulbs and I am hoping to have better luck this year...also I read somewhere to leave the light on 12 to 16 hours then 8 off, is this accurate? Is it true that the light should be as close the the plant without touching it? Thank you for your time and assistance!

Hi Kimbrie - There are many different types of plant lights. The most efficient ones are LED's; the worst are incandescent bulbs. Whatever you use should be listed as intended for plant growth so they are color-corrected to provide light in the right portion of the spectrum - primarily blue and red.

The closer the lights are to the plants, the more intense the light will be. 12 to 16 hours per day is accurate.

How do you know the ones you used last year are the wrong ones?

I was told by some of the members on this site last year when i posted some pics of my starts which were of course spindly, they sent pics of the lights which i saved but cant seem to find it anywhere.

6500 K, bulbs are want you want.

The t-5 LEDs, burn so cool, I've had seedlings grow against them, and not burn.
Other bulbs, you have to determine how close you can put lites, so as not to burn seedlings.

Do leave lites on for 16 hours.
Then, off 8 hours.

Ttfn 👍

Thank you for your insight. So you would suggest staying away from the indoor led growing lights? This is an inexpensive one I found but if they are not good I wont get them How much of an area/how many plants can 1 light bulb supply for?

No, LED's are your best choice.What Philip was saying is that because they do not generate any heat you can put the bulbs very close to the plant without harm. That is a good thing.

How great an area a single bulb will cover will depend on its distance from the plants. The closer the distance, the smaller the area covered, but the greater the intensity for those plants within range. Fluorescent tubes will cover a wider area. In general, only the plants directly underneath the bulbs will benefit from them.

Hi Kim 😀
That lite, might/maybe ? Would only support , 3, maybe 4 little pots, in a straight line.
Hears pics of mine, i bought at a hydroponics store, those guys know more than just growing marijuana #!!! It's hanging by 2 chains, screwed into ceiling, with S hooks for easy adjustment. Foil hanging over either side, for more refection.
Ends open, so fan can blow threw.
Did, I tell you, you need a fan ?
I can put 2, 10x20 trays, running lengthwise, under it.
You'll want them running lengthwise, so you can rotate each one 180 degrees every two days, because plants on either lengthwise side, are not quite directly under lites. Foil helps, but not quite.
Hope you understand that last bit, about rotating 180 degrees.
It's just my way of stretching the lengthwise limits of the light fixture. He. He. 😀👍.
You want shinny reflector, above lites. It helps. 👍!!!
A gal in gardening Dept, at HD last year, told me that they would be getting grow lites in sometime ???
She was very knowledgeable about grow lites. Well ! So ! ?🤔??? ............ I decided #!!! Nobody hear, or in Fresno's nurseries, had or knew a DAMMED, thing about grow lites !

I'LL, JUST go to the EXPERTS !😮! At one of the hydroponic shops.
And, sold ! I bought the lite. It was one hundred dollars. Then a few days latter, my sister decided she wanted one also. She went online.
She found one, same size as mine, only 2 bulbs, but same 6500k rating.
NOW's !😞! Hears the sad part.😟 She, got free shipping, and only paid fifty dollars , for her's. 😭😭😭Pout. Pout. Rolling on the floor laughing
Ho, wells !🤔? Dats da ways, da, cookie crumbles !

Those grow lights look awesome. I know I'm not the OP, but is there any lights available that mimic the Sun? Thanks.

I just cobbled some lights last night. I got full spectrum bulbs. Will those work? Either way it's better than what they had, being moved from one side of the house to the other following the sunlight. My whole set up was $32.00. (I already had the rack.) It's not pretty, but hopefully it will work. We're hitting 50s occasionally here.

I'm just starting seeds indoors for the first time this year, so I'm definitely no expert, but I came up with something basic and inexpensive that is working well for me. I found 4' long two bulb fluorescent shop light fixture that came with a plug in power cord and hanging chains (most seemed not to come with a plug) for about $12 each. I bought the bulbs that had the highest "k" number. I think they said they were for active areas. $10 for a two pack. And an inexpensive four tier plastic shelf. I think it was around $35. All from one of the big box home stores. So the whole set up was right around $100 total. My plants look healthy and green. I adjust the height of the lights as the plants grow.

Nessa : Hi 😎
Shop around, 6500K bulds are want you want to, START SEEDLINGS !
As I said, you can learn alot from a hydroponics store.

I can see the start of unspecific answers coming in, the same as when I asked about grow lites last year. To no avail.

Lastly. I'm going to add, that LEDs, are the best. There extra cost will also save you money, down the road, in electrical costs, and also, they last twice as long as regular florescent bulbs.

If ya don't belive me, do your own research ! Not hear. Since, I consider myself the best expert hear. So Y'all ! Go to Google.

CHEERS ! ITS BEER-THIRTY 👍
