Growing with Artificial Light  email this discussion to a friend?

myLot reputation of 98/100. EvrWonder (1930)   ranked 80 out of 1,674 in gardening 2 years ago

I have started my seeds. Yes, early but I think Spring is going to be here a lot more sooner than we think.
This year I am using a bench with grow lights but I am unsure how long to leave the lights on. I have been leaving them on from 7a.m. to 7p.m. Is that too long? I can't recall the hours that I used a few years back.
In any case, my tropical plants seem to love it, a lot.
I don't have a bench warmer, yet, so to heat the flats from the bottom but will be adding in the next couple of weeks.
Any words of advice, growing with artificial lights?
I am using it mostly to start the seeds and help the seedlings along.
Distance is a no brainer. I am more concerned about the hours.
I recall depending on what you want to do, determines the hours of light vs darkness.
Will enjoy reading all responses for sure and thank you in advance.

It mainly depends on the types of seedlings. Some do best with 16 hours of fluorescent lighting and some do fine with 12. You should do a search on growing seedlings and look up each individual type to see how they do best.

As for heating the flats, that is only helpful before they sprout. Afterwards, they should be kept cooler so they don't grow tall and leggy. Most seeds need warmth to germinate but need cooler temperatures to grow properly.

Good luck with your garden! I don't think we'll be seeing an early Spring here, especially because we have about two feet of snow still on the ground. We just got more snow, about three inches, yesterday. I'm beginning to think we're going to skip spring, summer and fall and go straight into next winter.

I'll be starting some of my own seeds in about a week and HOPE that I'm able to plant them outside when the time is right. But, after a grand total of 94 inches of snow (so far) this season, I'm thinking more like we'll have a very late Spring. After all this stuff thaws, the ground will be way too wet for awhile to plant anything. What a winter this has been!

Thank you for the info. Interesting about the seeds as I never knew this.
I will check it out. may take awhile as I have a ton of flats germinating.
Already getting heads popping out too :D I love this!
I understand about the heat. I just want to give the seeds the best environment to do their thing.
I heard that you people got a major dump of snow. We have sunny skies. Our crocuses, snow drops, daffodils and even the dandelions are blooming already. I noticed the snow drops early January.
Our winter was way too mild, especially for the Olympics not to mention the survival of the pine beetle.
Well, have fun germinating and thanks again for your response! Much appreciated.


myLot reputation of 99/100. mentalward (6157)   ranked 5 out of 1,674 in gardening  2 years ago

I love seeing the seedlings popping out, too. It never grows old. I'm as excited now as I was the very first time I started seedlings indoors. I call them my "babies". I tell my husband, "I got 4 new babies today!" He thinks I'm nuts. He just doesn't get it and leaves all the gardening to me.

I have eight 4-foot-long fluorescent lamps, each having two tubes and that probably won't be enough for everything I'll be starting indoors. Last year, I didn't have this many lamps and had flats in every sunny window and under every lamp in the house. LOL This year, I'll have better control over the seedlings, amount of light, air circulation and temperature.

Yes, we sure did get dumped on this year! I feel like I'm in a horror movie about the snow that never stopped. Even on days when we don't "officially" get snow, many of them have flurries. Normally, we get less than a foot for the season but, this year, we've had almost eight feet. I hope I never see another year like this one.

If I can find anything that lists the different seedlings and how much light each one needs, I'll let you know as soon as I can.


myLot reputation of 98/100. EvrWonder (1930)   ranked 80 out of 1,674 in gardening  2 years ago

Thank you. Yes the snow that you're getting is rather extreme. Stay warm & safe.
I call them my babies too. Lol. I get a lot of pleasure out of it also.
I have the four foot grow lights as well.
I have more babies today too. Seems each day, something more is coming through.
Sounds like you are going to have fun! Enjoy and thank you for your comment.

Evrwonder....great advice from Mentalward..but I tend to strike a Happy medium, most do well with 12 hours, sorta consistent with the daylight hours you are striking right now!

I couldn't justify buying a heating mat...so my potting bench has wire mesh over it, so when re-potting, the dirt falls thru to trays below...SO...I went to the local Thrift Store, where I bought an Electric blanket for $2.00...laid it over the metal mesh (for safety -fire..just in case) turned it on low...and if the low setting is above 72-75, just slightly raise the trays...works great, and cheap on power.

Marti........if you get any more SNOW...the only thing you will be growing this year is SNOWDROPS...and ICEPLANTS! LOL!

If I was smarter, Marti...I would know how to upload the pics..of daffodils blooming, they just opened yesterday! Happy Dirty Fingers, ladies..and Cheers!


myLot reputation of 99/100. mentalward (6157)   ranked 5 out of 1,674 in gardening  2 years ago

cry Snowdrops are very pretty but I need COLOR!!! The weather gurus are now telling us we could see more snow next week on Monday/Tuesday and again on Thursday. Sigh!

I'm going outside soon and poking some colorful silk flowers in the snow at the end of our driveway. I know my neighbors will get a kick out of them. lolthumbup


myLot reputation of 98/100. EvrWonder (1930)   ranked 80 out of 1,674 in gardening  2 years ago

Lol! mentalward; Good idea about the silk flowers. Great way to life spirits in cold winter weather. Have you got more snow yet?
perga; I have ben going for twelve hours, approximately. never any less. Seems to be doing great! I have more lights to set up however, which should help regarding the space factor. Then I will have more light space to fill up :D Yaaa!


myLot reputation of 99/100. mentalward (6157)   ranked 5 out of 1,674 in gardening  2 years ago

No more snow... yet. We're supposed to get more snow tomorrow night through Thursday night, though. They're saying "snow" but I'm hoping it's more like snow showers. The temps have been above freezing every day for about a week now and our unpaved road is extremely wet, not frozen anymore. I'm hoping that whatever snow we get won't accumulate.

If we do get more snow on the ground, I'm going to have to think about "planting" plastic veggies! lol


myLot reputation of 98/100. EvrWonder (1930)   ranked 80 out of 1,674 in gardening  2 years ago

I am hoping that for your sake, you do not get anymore snow on the growing. I have a hunch that plastic vegies would be lacking in nutrition and taste but would also be hard to chew much less digest.
The week end has passed now. How are you making out with the weather? Any baby plants sprouting yet?

I have given up trying ot out quess Mother Nature and now I just by seedlings after any chance of frost has passed. All in all I get as many veggies with less work and effort and not much more cost. Because of this I have forgotten rules about light and heat. If it was me I'd look it up on the Internet. Good Luck


myLot reputation of 98/100. EvrWonder (1930)   ranked 80 out of 1,674 in gardening  2 years ago

Thank you savypat. I am going to be doing further research here this week.
I really enjoy starting my own seeds.
Everything in the flower gardens are either from seed, division or cuttings.
As for vegies, I like to start my own tomatoes but also purchase a couple seedlings. We seed most of our own vegetable garden. It is very large and will be larger this year. Hopefully to resale.
I thoroughly enjoy harvest but also collecting seeds. It is a lot of fun for me but I can understand your point of view as it can be a lot of work when we could so easily just go buy the seedlings.
Thanks again for your response.

I have a tray of seedlings in my office and use 2 halogen spotlights as artificial lights. I also have a tray in the dining room and have a lamp with a clear 150 watt bulb. They both work great for me here in Minnesota. I leave mine on almost all the time until they are a couple inches tall then only when they need light do I turn the lamps back on.
As always.....
HAPPY POSTINGS FROM GRANDPA BOB!!`


myLot reputation of 98/100. EvrWonder (1930)   ranked 80 out of 1,674 in gardening  2 years ago

Thank you for your response. The halogens are useful but scare me so I use the florescent light fixtures with grow tubes. Works pretty good. I leave my lights on for twelve to fourteen hours until the seedlings are almost ready to plant out. I harden them off first. I can see the reasoning for leaving the lights on constant until the seeds sprout.
