I see some more light some want's to sell but are they usefull or is it worth spending money on?
Thank's for info... I'll try with uv bulbs two 10 -12 dollar/piece . A part of the growing area will have more uv light , the led have also one of 30 but uv-a *(4). I belive in fullspektrum as good as you can get inside. Copy the Sun.I think so and a few others do too. There are several uv threads.
