Grow Mediums Best Premade Soil?

[Tyler_Durden88]

Ok back on the soil train for my outdoor this coming season. Im trying to decide on either making a super soil from scratch or buying premade and tweaking it. I need alot of it like 150+ gallons of soil. They will be autoflowers so a lighter mix will be better. I was thinking of using happy frog and ocean forest with added coco coir and worm castings but that would be super exspensive. Anyone got any ideas or good soil recipes? Im in coco and am a little inexsperienced with soils. Any ideas will be appreciated.
@faded187 your in soil right?

Shit homie i was hopin to follow you lol. First time organic but this is what ive done so far. Should be right around 150 gallons.

i also threw in some shrimp meal, high phos bat, perlite, lime lava rock ancient forest compost, black kow compost 2 bags coco, another big bag worm castings all for right around $300.. keep in mind thats concentrate and have to buy prolly 10 more bags dr earth. Would love to use ocean forest cause thats what ive always bought and tweaked for indoor but like you said to expensive. My shits been cooking for about 3 wks now. Ph is up to 5.2 and still climbing. Itching to throw something in it
