Hey, I don't wanna bury out an old thread, but I don't feel like creating a completely new thread just for this question, and it's about megacrop.
I live in Germany, and I'm actually able to import this stuff, which is nice. I've looked at this stuff for a VERY long time now. Problem is that I currently still have 1 leftover bag of "Biobizz All Mix", which is a peat-moss based "organic" substrate. I don't want to buy another bag of substrate, as it's almost impossible currently in Germany (legalization, all shops are EMPTY, seriously! They sell bags of soil for 5x the price on Ebay now, it's insane). It's worm castings, perlite, peat moss, pre-amended for 4-6 weeks, that kinda stuff. I plan on doing autoflowers with one re-pot, from solo cup with a light seedling mix (larger ones, 450ml), to final pot, 14L All Mix (around 3.5 gallon pots).
Now I want to ask the professionals who have some experience with organics and synthetics, both - This substrate is considered organic because the microbes in there feed the roots, and buffer out any PH fluctuations. The substrates base PH is 6.2, and it recommends to feed between 6.3-7PH. Now my question to all of this is - If I start using megacrop as soon as the substrate is all eaten up by roots, what PH should I aim for? This confuses me EXTREMELY, but that's because I'm still new to all of this. What PH should I aim for with these kind of synthetic nutrients, if I use an organic substrate that buffers PH to a specific range? I see peat-moss users usually go for 5.8PH, but this is an organic mixture which wants higher PH, so I'm absolutely confused!
I would be very happy if someone can explain if this works, and if it does, how does this work?
