Grow lights and bonsai was created by Grugelnator

Posted 5 years 9 months ago #48057
Hello everyone I decided to start growing bonsai trees from seeds and I was wondering if it makes any difference if I grow them under a led grow light? Does it reduce the grow time and give me a more leafy tree or is it just a waste of electricity? I have never done this before and I'm a complete novice so any tips and tricks you guys can give me as greatly appreciated! :)

Just made a trip through sweden. Well, not really, I used Google maps / Streetview. Awesome scenery. Lots of trees - including trees that are suitable for bonsai. All without a growlight (or umbrella or heater).

Ideal!! If sweden is anything like Norway, you can find an abundance of bonsai growing in forests. Because of the lack of sunlight, and the long winters with lots of snow the trees are small/gnarly and old without becoming tall.

We keep our tropicals under grow lights while they are indoors for the winter. Our house has poor southern exposure so this is the best route for us. (We also have 150+ succulents and cacti that have high light requirements to stay compact and/or maximize their color. We have 8(?!) LED grow lights throughout the house so it's just a matter of shuffling things around to make space when we bring everything inside in the fall.)

It is true that trees in Sweden grow with a lot less sunlight than trees in Alabama, where we get 8-9 hours a day in winter and lows below freezing rarely.

But, different species have different requirements for temperature and sunlight. And, subspecies vary the same way. If you get a catalog to order fruit trees, they come with specific requirements for daylight hours, nights below freezing, etc., in order to grow and for the fruit to set. Virginia pines won't grow around here because we don't get enough cold. They may last a year, but they die within a couple of years. White pines from around here won't live in New York where they have months of freezing weather.

You have to look at the individual tree species, and then you have to realize that the tree growing in the ground has the roots in a large heat sink, while in the pot the temperature varies much faster with the air.

I was thinking about grow lights for the indoors trees. They will be going outside in a couple of days, so I have put that decision off successfully.

Natural sunlight works. This african bluerain popping through after just 7 days in the soil. First of the 6 in that tray. This time of year (spring and summer for scandinavia) has enough light.

Sounds like a literal translation for bl?regn (or Blauwe regen, which sounds similar, in Dutch). Wisteria, I guess?
