Help with T5 bulb selection

[chris88]

2 years yikes. 9-12 months max is all they are really good for. The spectrum shifts over time and the par drops big time. there are much better options out there. you have 4 of the lowest par bulbs going there all peaking in the same spectrum. use the combo i suggested and you will get much higher par, better color, and it will fill in the blanks that your hallides leave out.
