So this year I will be taking on several sativa, projects. I haven’t traditionally grown too many sativas. I have done a few but mostly haze hybrids.
I usually grow in coco but for these sativa projects, I was thinking about going with a nice, organic soil.
I was wondering if anybody was familiar with the M3 soil?its supposed to feed the plant for the entire life cycle. I was wondering if this would be good stuff to put some landraces in? I know, or at least I have read that sativas don’t really like much nutrients in flower. I’m just looking for some pointers for doing landraces. Especially when it comes to feeding them in flower to get the largest yield and best quality i can.
Thanks!

Hey soil grower out here in Hawai’i, I use this soil, and I’ll bulk it out with Promix HP, and perlite! Works great for sativa out here.

It would have to be a pretty big pot. I prefer bottles personally.

I had great success with Jobes 4-4-4 pellets. Grew a Malawi and it loved it.
I used Black Gold and mixed with some coco.

Whaddya up, king, I’m in the same situation. I’m going to use a local soil (Royal Gold Kings Mix) with added 5% biochar (going to reuse) and BAS 3.0 nutrients. I’ve grown sativa landraces hydroponically but it was super challenging (5 gallon buckets, clay pellets, RAW salts) so this time I’m doing living soil so the plants can feed themselves. 3 gallon pots are too small for a water only grow even if you top dress and amend. If you’re going to add nutes you could use smaller pots but for living soil, water only I think your looking at 10 gallon or more. I’m personally using air pots with the final home a 15 g. fabric bag.

You’d be surprised, I focus on the biology in the soil above anything else and rarely have to feed my plants. (I occasionally add some calcium and bone extract last half of flower - home made/free inputs only)
Sometimes - 2 litre pots and I can get away with it - with quality harvest on the other side. Also animal poop and worm castings goes along way. (rabbit, moose, goat, sheep, bat etc)

1 gallon pots. I shove 9 of them into a 2x2

I call this mix, @YoBigdaddy’s Sativa Dirt, and I’ve used it for Acapulco Gold, Angola Red, and Swazi Gold with excellent results. Most of the nitrogen is found in the various mineral amendments, so it breaks down very slowly, and provides a steady amount of N. He puts in a lot of stuff I’ve never had, like IMO4, and leaf litter, but it still worked well for me.

Hey Guitarzan, I seen your stuff on Strainly!
Wow, that’s one hell of a soil mix. It might be a little too complicated for my situation, but I bet it grows one hell of a tasty plant. We have a soil mix made he in Michigan , that sounds a lot like that one, it’s called M3 mix. Mixed in small batches with a proprietary formula of ingredients. I have personally never used it as I am mainly a Coco grower, but for these Sats, I wanted to go a decidedly organic approach. It just seems right to grow a landrace in some good ole organic soil. I’m really thinking about using that M3 mix. It has a mix of fast and slow release ingredients and I think it comes pre-cooked.
Thanks for the suggestion.

Damn, 15 gallon bags. In coco I’ve never gone above a 3 gal. Still…I was planning on using the 5 gal. Airpots I have, the pots with the holes all over them…5 gals is all I can afford to fill.

I bet there is something magical in Hawaiian soil Soda. The land of Aloha, had a special vibe to it when I was there. Lush jungles ages old, I bet the humus is rich in those parts.

Maybe you should sell Hawaiian Soil. I bet people would pay…
Be a hella shipping cost though…lol

I think that Ag regulations would prevent it and moving any dirt from here to there, imo, would be pilau. but I do think because of our volcanic creation that our soil is probably a lot higher in micro minerals, specifically silica and sulfurs.

Is this it cap??
I know that most of our native dirt is Ph’ed acidic as well

What kind of sativas are you planning on growing?
In general I think relying heavily on compost is a safe strategy - generally won’t burn or overwhelm plants and will allow them to extract nutrients as needed over a long period of time. Also up-potting after stretch is a good strategy - it provides a better proportion of nutrients for a long flowering cycle while keeping size manageable.
