Also should add this, cocnutz convinced me to up my temp a bit, took me awhile to actually do it, but holy shit! It made a difference. Definitely more aggressive. If you normally run a cooler room you should definitely consider upping the temp. I couldn't put an exact number on it, but just run it slightly hotter than you would normally i raised mine just a couple of degrees, got the lamp higher to compensate and I am supremely impressed.
My impression so far is 6/9 silica/sm90 is so simple there is nothing to really fuck with there. It's so simple it's almost not worth talking about, stuff just works. Because it's so simple and cheap, you can put a bit more time and money into your environment. IMHO the best thing you could do to a 6/9 garden is get the environment perfect. So much more important than a bunch of boosters.
