I have been doing some research on what soil is good for auto flowers because I am on my 3rd auto grow and all tree of them shows the same nutrient deficiency in all 3 grows. My personal opinion is that autos and their short VEG to FLOWER stage has a lot to do with it. "The soil is to hot" is what I hear A LOT" so I dont know any thing about , don't have the time and knowledge, not even know were to start....So I came across this soil that is Smoking Tomatoes Soil: here is a link to their web site........SOILThey are based in Michigan so thats a 4-6 hour drive, now for me to drive 6 hrs for some soil sounds crazy, I know..if only they would delivery..I would love from someone that has used this kind of soil before and how was it??? There's moor I know this is the last ?? I found this soil just like the one that was mentioned earlier and I can get this delivered to my local Hardware Store, but it likes $50 a bag of 18 LBS, now the other soil is $15 a bag at, well it does not say?? BUT its $15 a bag..Let me get back to the soil its called SOHUM Living soil, just adding water only is Like PARADISE to me, I personally hate mixing chemicals and adding dry fertilizer every time I feed them Its a mess after feeding I have to clean the reservoir and every thing else..you know what I am talking about.. so by just adding water is a dream come true to me....same as this soil want to hear other thoughts on this .
