Well, most of you know - I'm a DIY guy and make most of the ferts I use. But even I occassionally pour from the bottle.
.
The following products are Ohsogreen approved - Earth Juice, Metanaturals, Age Old Organics, Botanicare Pure Blend Pro Series and BMO ferts. All of these are of good quality and get the job done.
.
There are lots of others to choose from and they may also be good. These are just the ones I have used and really liked.
.
Don't let fancy labels and outrageous claims (which always have high prices) fool you into thinking it's a better product. Most of those high dollar ferts don't perform any better - they just look nicer.
.
Hope this helps...
