Strarting seed in super soil?

bought extra soil this year I’m going to make some super soil with amendments I also bought and keeping them cooking in my basement until next year. If I start a plant In a cup in this mix will it burn and kill my plants. The soil amendment company says won’t burn plants but never cooked or used super soil before. I know not to feed liquid nutes to it until their outside (starting in supersoil then transplant in regular) but liquid nutes aren’t to be fed until 2nd or 3rd week and even then your suppose to start off at 1/4-1/2 strength

I don't know what super soil is exactly but this is what I do...I start my seeds with black gold organic soil. I put the soil in 5" fabric pots then set the fabric pot in a plastic Solo Cup. I give them only distilled water for two weeks. When they've gone from seedling to vegetative state I transplant the 5" grow bag into my larger pot with Fox Farm Ocean Forest mixed with Roots Organics ROD75 (bat guano, worm castings, coco, ect..) and I also add nutrients into the feeding cycle. Don't know if that answers your question exactly but I hope it helps.

Definitely have to be careful starting in hot soil!! Some might be tough enough to take it but it can definitely cook some baby’s.

Super soil is the bat guano worm casting that they add to regular soil and other stuff like kelp meal alfalfa meal etc then you put it in a container and keep it warm for a month or so and the soil can replace the liquid nutrients all you have to do is water with plain old regular water ph’d of course and that’s it should give a similar yield to fox farm or advanced nutrients depending

Idk I did add regular amendments to the soil early on this year they died but it was over watering some strains definetly didn’t like something the leaves were scaly and pretty rough could’ve been ph issue though

What I do for seed starts is get three buckets. One of my regular soil mix {which is pretty hot}, one of my Sungro potting soil {which has no ferts}, and one a 50/50 mix of the other two.

I fill the bottom 1/3 of the cup or pot with the hot mix, the middle 1/3 with the 50/50 mix, and the top 1/3 with the Sungro potting soil. Put the seed in place, pointy end up, and cover with more of the Sungro.

If you are wanting to go ahead and get your big pots or holes going, you can just sink the gallon pot in the bigger pot until it's ready for transplant.

Super soil is going to be too hot for seeds. It is intended to be used as only a bottom layer in your pots, and you fill the rest with regular bagged soil.

That helped a lot cause by the time they reach the bottom they’ll be grown enough for nutes I thinks I’ll try this way and see how it works out thanks

You can fill with the container with super soil if you like but you have to get them there step by step. Start in unfertilized peat/seedling mix. Then transplant half and half or fill the bottom. Let it get adjusted and then move it to full super soil mix.

Fyi, i mix my own soil and i only do 1 transplant. I start in recycled mix then into full super soil. The strains i have all respond well to it. But if its your first time with that specific strain starting slow would be better.

Damn though I plant in ground and wanted the supersoil to feed the tap root all season and feed the stretching roots looking for water the liquid nutes but I guess it doesn’t really matter either way it’s gonna grow about the same probably

Wanted to give it extra nutes that aren’t listed on my bottles

Maybe the bottoms 1/4 of the pot or cup and the rest fill with jiffy seed starter or coco with maybe light guano and castings would work..that’s what I do

Jiffy gave me damping off so I don’t use it no more maybe I’ll go with coco

Unless the plants are already 1ft+ tall then you will definitely burn (and possibly kill) anything smaller in supersoil. If the supersoil in question has anything like Blood/Bone Meals, any type of Guano, or Alfalfa Meal then you can definitely burn plants using those amendments. I'd consider looking elsewhere for your business in the future if the company you purchased from said supersoil won't burn plants, they're setting people up for failure with that kind of advice!

The energy from the decomposition process can make things as hot as 150 degrees, and if you put a clone/seedling or even a 1ft tall plant in that soil and expose the roots to those kind of temps then you will for sure have issues. Deformed and stunted plants at best, and dead plants at the worst.

Assuming this is SubCool's Supersoil recipe, you'll want to do the following. First, you'll need a base mix that isn't so heavy on nutes. Mix it yourself with peat, perlite, and compost. If you can't build your own base soil then I recommend Fox Farm's Happy Frog, only bag I know of that comes in 2cuft instead of 1.5cuft. Happy Frog has good stuff in it and is my go-to when I'm buying bagged soil, which is quite rare these days. You want to put the supersoil at the bottom 1/3 of the pot. On top of that, 1/3 of supersoil mixed with base soil. Then, the final top 1/3 layer of soil will be purely base soil. This way your roots won't be burned because it won't be exposed to the supersoil pre-maturely. It will grow through the base soil into the base+supersoil mix, then finally into the supersoil in the bottom of the pot. Nothing will burn this way.

As for liquid nutes, save your money and don't even buy them. Unless you're using Fish Hydrolysate, Fish Emulsion, Liquid Seaweed, or Silica then you should stay away from bottles. The reason is because chemical based nutrients will kill the microbes in your super soil, effectively defeating the purpose of purchasing the supersoil in the first place. The idea behind supersoil is water only. You can top dress with Neem Seed Meal (6-1-2) in veg, then switch over to Crab Meal (2-3-1) or Guano (0-5-0) in flower and that should really be all you need. If you have heavy feeders, Fish Emulsion in veg and Fish Hydrolysate in flower.

Look into Clackamas Coot's soil recipe, which is a revised version of Cornell University's recipe. Equal parts peat, compost, and perlite. The only amendments are Crab, Neem, and Kelp Meals with some sort of mineral amendment, typically basalt, glacial rock dust, or azomite if you can't find the first two. Mix is ready to go the second it's mixed, and will not burn your plants. Been my go to for the last 4 years or so now. I top dress every month and use one of the bottled products mentioned above if I'm dealing with a heavy feeder.

Damn dude definetly wasn’t expecting an answer like this very informative lol what would you say to using carbonated water and spraying outdoor plants to add co2 to an outdoor grow?

Happy to be of service.

Spraying with carbonated water is something I haven't heard of, personally. I can't comment on the CO2 foliar as I don't have much experience with it. Increasing yields by 25% with just carbonated water is a pretty bold claim to make though.

I took a look at the second link you posted, which lead me to the following presentation(https://assets-powerstores-com.s3.amazonaws.com/data/org/15680/media/doc/co2_foliar_spray_benefits_on_cannabis_pathogens-e68a22e810924d4a5645fc2816cfdd45.pdf) on this site (https://www.co2gro.ca/pages/results). From the looks of it, the second article in question is referring to a product that acts as a fogger/mister to keep a constant mist of carbonated water in the greenhouse. That's actually pretty genius, and with something like that I could definitely see how it's possible. Bet you could DIY something like that, get a CO2 to carbonate a reservoir that's connected to a misting set up and one might be able to get similar results. Hard to say without a CO2 meter to see PPMs myself though.

As for spraying carbonated water from a pump sprayer, it would show a slight increase in yields due to the extra CO2. It's just that you won't have as much CO2 from a pump sprayer as opposed to the misting system. Without the constant fog/mist in the room there won't be a constant source of CO2. So my thinking is that the plant would intake the CO2 from the water misted on the plants, it's just that the plants will only received extra CO2 for as long as they're being sprayed.

Definitely something to experiment with, I'd like to try a side by side with some clones in the next week or two. But until one of us can confirm the claims in the article, I'm going to say that going the pump spray route will just be a waste of time and money. But that's just me.
