Help with soil???

Soil preference is truly up to you, but promix HP

I'd say biobizz lightmix, I find allmix a little rich for autos.

for me personally Biobizz ALL MIX was working best. I was enriching it with around 10% of worm castings/humus , usually i was bying same Biobizz brand. I dumped all light mixes, saw mostly bad results with them , same if people mix soil and coco. saw good result in peat and soil mixes. foxfarm was crap for me. hp pro mix was too rich, but maybe i would try this blend again. now trying to mix my own, first time ever and only for outdoors plants, only because not sure with results i have doubts. branded too expensive and hard to get in my current country. hope it helps !
