    If people are raising vegetable starts, tomatoes from seed, etc. or any other plants from seed, cool white bulbs are perfectly adequate and much cheaper.

    I learned in my garden reading that warm-spectrum light bulbs, or 'full-spectrum' bulbs, or 'grow lights' are only needed for plants when they reach the flowering/fruiting stage. For plants in the first developing stage they aren't needed. Or I should say, those spectrums aren't needed.

    I used to grow magnificent vegetables that I started indoors--tomatoes, peppers, eggplant, okra, herbs, etc, etc. all with cheap florescent cool-white bulbs. These plants usually spent just a few weeks indoors until transplanted outside.

    Where in the Constitution does it say: "...on behalf of corporate interests" ???

      better return on investment, because you can always just use more lights for that.  I start my tomato seedlings under whatever 40 watt shop bulbs are cheapest.
