Hey Weezard,

I really like the variable Red:Blue ratio. It reminds me of the company in NL that uses a computer control to adjust light spectrum for specific plants.

I suggest "dial-a-stretch". lol

Very nice work.

If I were to post my picks for power supply, resistor ratings / values, etc., would you critique and perhaps offer some guidance? I have already purchased Rating: 5
