Haha that's a good outlook
I can say that going organic can potentially be expensive to start, but does save money in the long run, because the idea is that ya build the soil nicely, and then don't have to buy and add those expensive chemical nutrients. But it can seem scary at first. I'm doing mine in stages, so I don't break the bank all at once. The basic idea is that ya have the soil base, and add ammendments. The very cheapest I think an organic switch can be done, and with just stuff from the store (walmart / lowes / home depot / nursery) is probably about like this :
A bag of MG Organic Choice potting or garden mix, and an equal or slightly greater amount from a cube of Premier peat, mixed as a base. The Premier peat comes in a big white and green rectangular cube at Lowes. Then some seaweed fertilizer, some kinda compost (cow / mushroom / worm), some vermiculite / perlite, and a dash of epsom salt. That would probably be the absolute bare minimum mix... Missing some goodies, but that could be a minimum mix. I've read some people have success in growing just in the MG Organic Choice soil alone
I think if I had to go to Lowes and just buy 1 bag of something to grow in, that might probably be my choice, but there are very few choices for my local stores lol. These are just my thoughts and opinions, which really aren't worth much cuz I'm still just learning about growing Cannabis too hehe
