is a, 18W Phillips genie, sufficient artificial light for indoor growing of plants?
I have 3 African tree seedlings in pots, Acacia Galpinii, to be exact. I want to make bonsais out of them but I live in Holland and do not have enough natural light in the house. They need to be outside actually but our climate is to cold for this kind of tree, so I went looking for grow lights and the best I could find was energy saving lamps that emit 100W of light using 18W of energy. I do not know if it would be enough to sustain the plants through the winter and do I need more than 3 of these laps.
Not likely.
The sun is giving them 1000Watts and that is what they are aiming for as a ‘full meal’ for the plants.
If you are only getting 18Watts of energy in I can’t see how you get 100Watts out as you can’t make energy from nothing. However, even assuming 100 Watts that is going to be pretty low.
I personally tried something like what you are doing here in Canada with a Mango tree from the Philippines. I used 3 x 75Watt grow lights. It was a very unhappy mango tree, it did grow–sort of.
It grew very spindly and seemed to be ‘reaching’ for the light as it wasn’t enough so it ended up stretched and unattractive.
It is not energy efficient, but hydroponic grow lights are going to be your best choice for a healthy tree (metal halide type)

Three bulbs kept close to the leaves and in a sunny window should work fine. RScott

If you can fit 3 or more placed around the plants that should be sufficient light remember that in Africa the nights are darker and come in earlier so if you extend the time of artificial light by about 3 hours this should work.
