ALL-MIX Substrates
All-Mix is a heavily pre-fertilized soil mix-ture designed to emulate rich outdoor soil with a full micro active eco system but in such a way that it has enough power to sustain lush plant growth for a couple of weeks with no extra fertilizer input re-quired. With All-Mix we have a fertile field throughout the year.
...for seedlings i try to work w/ any material where: N=<1.0, P=<1.0, K=<1.0
Starting again now, would b faster n waiting out the scrubs... YMMV, All grows r unique.
