Growing medium

A good quailty soil that's buffered I prefer over coco coir, more forgiving IMO. I would suggest looking at Peat based medium like Pro-Mix HP-M. I started recently using Pro-Mix HP-M and it is in every way superior to soil. It doesn't have nutrients in it so you start feeding early but it's buffered to help with ph. Coco is more like hydro IMO. Soil is soil Peat/Pro-Mix is between the 2.

Growing in the ground has its benefits; The soil contains bacteria that can enter into symbiosis with the roots and thereby nourish them. Also, the soil must be loose so that the roots can breathe. If the soil is too compacted, the roots will not breathe properly and the plant will not be able to reach its full potential. Also, the soil does not need to be fertilized as often, unlike coconut substrate.As for the coconut substrate, it is quite loose and does not form lumps, which gives more air to the roots and promotes the development of a powerful root system. Also, if you use a fabric pot, all excess water will drain through it, preventing the plant from overwatering. Also, since it is a coir substrate, it is best to mix Mycorrhiza for better nutrient uptake by the plant roots.And since this is a coconut substrate, it does not have many nutrients, so it needs to be fed more often than soil. The frequency of fertilization varies and depends on the fertilizer; some manufacturers advise watering the coconut substrate every day

is it soil vs coir only??? Soil outdoors worked well for me. in doors not as well as coir. but good advice below. do what you want. its a plant, it will grow.

A plant is a plant, in this context. Autos merely go into flower on their own time frame. what's best for photos will be best for autos too. i am not a fan of coco coir, but others love it. You get one improperly processed batch of coco and you got a room full of sick plants, lol, but some will tell you it's the best. go soilless. Promix is fairly cheap options - BX or HP. Mix in some perlite or vermiculite #3 to increase that portion of drainage amendment to 50% of volume. This is basically what dr. bugbee says was the best substrate they tested. Think that tidbit is in the video titled "Maximizing yield of cannabis" Even so, you'll never notice a difference using coco coir by comparison and doing all other things the same way. Maybe with 100 clones and comparing you could see one has an advantage or not and it'd be a small difference regardless of which it is. Soilless/hydro methods are the easiest to fertilize, imo. As long as you don't follow some esoteric magic. When you control everything relative to nutes, it's much easier to diagnose. an inert substrate will be easier than hydro. hydro might have a higher peak, but again, if you do things well with each it'll be a minor difference. Can even do 3x/day fertigation with the right setup of soilless and match growth rates of any hydro setup. living soil/super soil is a long process of trial and error learning how to constitute the soil so you don't have to fertilizer for 100+ days, unless someone has a sure-fire recipe for you to use. The benefits of only having to add water doesn't need to be explained, but you'll probably have slightly slower growth rates, too.

Skip the media altogether and just do DWC hydro. Basically just need a 5 gallon bucket and a good aquarium pump. My thoughts on the others, you'll achieve larger plants in coco/hydro if done properly but a lot of flavor chasers prefer the sun and soil combo for their flowers.

The best just comes down to whatever is best for you. It’s about your preference, availability, etc. Maybe try a plant each way and see what you’re most happy with.

Gotta specify a bit on what you mean with "best" ... Both have their Pro/Cons depending on what you are trying to achieve.

Wazzzzzzzaaaaapppppp 😉 lol Hey there I think alot of people will tell you. Coco and living soil and such witch can be expensive One option is go to your local hudro store kr gardening store and talk with the worker about the options they have look for something that has good aeriaton and doesn't have long lasting nutrients already in it Another option is the simple fox farm socks that you find almost everywhere and there nutrients aswell. There are good charts to tell you what to use and when In my personal opinion I would go buy some promix HP get some work casting and some kelp meal and some mycinohaze granular and some extra perlite also you could get some type of thing like gia green 444 that you can mix in the soil aswell
