i’m looking for advice/opinions on premix soil and soil conditioners for an outdoor in ground gorilla grow. i can visit the location fairly easy but would prefer not to for the most part. i will be growing fast buds gelato autos and am located at 40* north latitude wise. I live in farm country with corn and soy bean fields as far as the eye can see. the ground produces some of the best crops in the states, however i want to give these plants the best life possible and hopefully increase yields. my plan is to dig about 12”x12” holes maybe 12” or 18” deep (opinions on hole size are also welcome) and either fill the holes with a premix water only super soil or mix in a conditioner with the dirt and fill the hole back in. main supply of water being rain but also hand watering if a dry spell were to arise. any one have experience growing like this? any premix recommendations? any input will be greatly appreciated, thanks in advance
