Happy Holidays!
I have a quick question to get the old grey cells moving today...

You're mixing a batch of supersoil and you're missing an amendment. Which one amendment do you think could be skipped every time, and yet you personally are not willing to skip it? What is the reason you feel your cannabis is inferior without it?

Is there anything similar you would substitute for it, if you had to?

Thank you for engaging, may the rest of this year be awesome for you.

I personally think you can skip guanos, you can get other materials like blood meal, feather meal, alfalfa meals etc for the nitrogen, bone meal, soft rock phosphate for P or you can just use the guanos for tea instead of mixing in the soil.

I would not skip on rock dust, depending on which rock dust you use (basalt, gypsum, calcitic lime or oyster shell, soft rock phosphate etc) This is for no till or recycled soil, they are more long term investment, if just a one use soil I would not skip on the earth worm castings, too much biology to lose out on.

Awesome, I figured a few things might stand out and I hadn't considered rock dust. I've heard guano farming is very destructive to the animal populations. :( I'm glad to hear it can be skipped.

So rock dust for no till or recycling soil and earthworm castings for one use soils. Greatly appreciated.

Earth worm castings.

Do not skip on those.

Aside from being a great and fast available source of N, it comes with a lot of beneficial microbial components, there are probably mycos and other fungi in there as well it's just all around great and probably one of the more crucial components I would say.

i agree......you could plant clones in 70% ewc and 30% perlite and they love it.....you cannot over fert with ewc....

I would say crab/shrimp meal. I did great without it for years but it seems to speed harvest, add frost and keep bugs away. It seems to knock about a week off flowering for me and makes some strains more frosty for me too. Worm castings are vital in my opinion and cannot be skipped. As soon as I started using castings almost 20 years ago my crops did so much better. Its the best amendment to your soil Ive found in my many years of growing and Ive tried them all. If I had to pick an alternative to crab/shrimp meal it would be insect frass but its way too expensive.

Depends on budget.

In outdoor native soil, just guano will sustain a plant just fine. Again, it all depends on budget. If they are guerilla plants with no real guarantee, why put a fortune in them?

Seed already costs so much.

With indoor plants and making soil, it's easy to get insecure about the soil. Outdoor soil around here has lot's of life and glacier minerals. The only thing lacking is all in the guano.

So my answer is guano. Highly concentrated and full of goodies!

Great information everyone, I really appreciate you sharing. As always, it's amazing how information dense each description has been.

Awesome!

Kelp and Compost/Worm castings

Kelp has all the micro nutrients and trace minerals but you could use rock dust for some of this. I don't usually skip out on Kelp but it can be expensive.

Compost or worm castings help add biology and help create an environment that is conducive to biology, as well as help with buffering the soil when it comes to pH, salts etc. Adding humus and organic matter are pretty much a fix all for most issues in your soil.

If it was just one I could use every time it would be good quality compost/castings.

It depends from many key-points

but anyway my MUST is LEONARDITE ... u should discover why
