Hello :)

I have recently set up a small indoor greenhouse in order to start growing mango, orange and lemon tress from seed. I know these type of plants need warmth and eventually a lot of sunlight so i decided to add a heat mat and growing lights (I live in an old Victorian flat with 125 year old windows and no windowsills so I cannot put plants in front of them as it would be too cold and there is nowhere to place them). I had a spare LED strip light that I was using for my aquarium and wondered if this would work for my plants. I've read that plants require primarily red and blue light and the LEDs have a setting that means they can fade between all colours. Would this work as a grow light as it is going through the whole colour spectrum?

Thank you in advance.

White light has the entire color spectrum in it and plants are very capable of sorting out the colors they need on their own. The important part is having a light that is considered a "daylight" bulb. If the light your bulb is giving off appears white or bluish, it is a daylight bulb. If it appear yellowish, its not.

You may have to place your light very close to your plants, maybe only a couple inches above them, so watch for heat build up. Plant or reptile heat mats always help in seed germination.

Your house sounds awesome (except for the heating bill)
