Has anyone used techiflora synthetic fertilizers in happy frog potting soil? Any suggestions on what fertilizers work best in happy frog or any suggestions on what not to use?
I personally use X nutrients, I started using Fox farms trio first but wasn't my cup of tea. Any of them will work, you just have to find what works best for you and your tastes.
Edit: Are you wanting to stay organic? If so, synthetics will toss the 100% organic right out the window. If your staying organic research some guano and compost teas.
