We want to share a photo that a customer sent us.

This is a test carried out on two vases of geraniums, of identical life and species.

The one on the right grew in a greenhouse with ambient light only, the one on the left, in a greenhouse under our lamps, model STL H1. The result is truly amazing!

If you had any doubts about the effectiveness of the light for growth, we believe we have resolved it, however, do not forget that the light must be efficient, the right dose both for cultivation and for the economic cost of energy (the binomial plus energy plus harvested) and, let us not forget, for the environment.
