I live in Ohio and brought my trees inside till spring. This is my first year doing this and I'm concerned about not enough lighting and making it through winter.

I've been looking at LED setups on amazon and wondered if I should bother. I don't have a very good south facing window to set up in so would it be worth the investment?

What trees do you have? if they are not tropical psecies they need to be outside

I have two pomegranate and a powderpuff

I use architect's lamps with 100W LED 5000K bulbs.
- Lamps are easily obtainable at Goodwill stores
- LED bulbs should be about 5000K, which are similar in colour to daylight
- Lights should be used only during daylight hours, to give plants rest for the night

I used this system last winter for my tropical Jerusalem Cherry trees with great results and will be continuing for the time to come.

Thanks for the suggestions, I will see what I can find.
