![]() By all means try a different bulb, it's a cheap experiment, however if you have a low nutrient system, are running heavy amounts of GFO and or cabon dosing, or have a low bio load you may just not have enough nutients in your system to support heavy growth of cheto (not a bad thing). I have only havested mine once in maybe 10 months since starting to run GFO.
