90 day Soi Mixl ?

Ok I'm Looking at doing a 12/12 from seed grow. I know from researching the strain it will only take roughly 90 days start to finish. My question is What is a good soil to use so all I have to do is Water with plain water(maybe a little Kelp added). I want to a have soil that will provide everything my plants will need. So All I have to do is water and feed them no Nutrients..

For a soil to last you 90 days with just feeding water only is going to be amended quite abit some good organic amendments to use are Kelp meal, alfalfa meal, crabshell meal, neem meal ect... Always use a good source of humus like wom castings, or good quality compost, they contains billions of good soil bacteria and fungi that help break down the organic amendments into usable forms for the plant to uptake, you should also let your soil mix "cook" for about 4 weeks before using it This means just letting the soil sit for a month after you add the amendments this will give the soil live time to break down the amendments into usable forms and won't burn the plant roots when you use it. Rock dusts are also very important, they give the soil bacteria and fungi something to hold onto and make their homes so they can then breed/feed and go to work... You could either buy a store bought mix and add those amendments to it or make your own soil mix, My soil mix when I get round to making it will consists of:
1/3 mix of homemade compost and worm castings.
1/3 mix of peat and coco coir
1/3 mix of perlite/pumice and rice hulls if I can get my hands on them..

To this mix I will be adding Kelp meal, Alfalfa meal, Neem meal, Crabshell meal.. I will add these onto a tub using equal parts and then use 2-3 cups of that mix per cubit foot(7.5gal) of soil mix I will also be adding 4-5 cups of rock dusts per cubit foot..

I hope this helps you, I know making your own soil mix will be 100X better than a store bought soil like foxfarms or roots organic...

If you don't want to make your own compost and worm castings then source some locally from private nurseries they will serve you better as the humus source is your most important thing in any organic soil mix

Thanks For sharing the Info

No problem mate, keep me updated would love to hear what you decide to do

Looks like Lumps traditional mix to me...got that one memorized lol. w89 you're my favorite new member haha. Keep up the good shit.

Thanks dude I will try help out who I can with my limited knowledge

If you know about Lumps your knowledge isn't limited you just need to do some more reading haha. I'm up till like 3 every morning deep in old grasscity threads filing my brain and my notebook with priceless info. Definitely going to start a thread soon that is dedicated to those on GC and ICmag who are spreading organic knowledge...I just gotta compile everything first. Give me a week or two and we'll see where I'm at...

cool looking forward to it

@gandrews76 The most important thing in your soil is your humus source. All the amendments in the world cant fix a bad humus. Source quality EWC or Compost and minimal amendments are needed.
