I just bought an Aqueon 24" dual bulb T5NO fixture half priced for $30. However I just learned of the importance of good quality reflectors and HO vs. NO on Hoppy's thread. I've found a good price on a Hagen Glo single bulb 24" T5HO for $70. The Glo fixture seems to have at least a decent or very good reflector. According to Hoppy's graph I should be able to grow even high light plants with the single Glo T5HO fixture. I still have the box and receipt to the Aqueon fixture. Would it be worth spending the extra money for the Glo fixture and the ability to grow any plant I'd like?
