Supersoil mix including coffee grounds, what's your experience?

Whenever one thinks of amendments you need to be careful about whatever it is you put in and regardless of what it is you need to know a few things with regard to how it will react with the existing PH, some amendments release based on ph, so can sit dormant until a ph spike unleashes toxic levels all at once, is it readily available in water soluble form? How long does it take to break down if not? I read that for optimal plant growth to occur, having around 5% organic matter or thereabouts is best at any given time in a soil composition, not to say you can't grow with more or less, tests are in and plant growth is better when its kept thereabouts 5%. Try to limit the bacterial load of any given medium, 45% minerals 50% pore space, 5% organic matter. This, coupled with airpots, will allow you to never overwater and create a perfect wet/dry cycle suited to your watering habits. Coffee grounds is a valid fertilizer that also adds organic matter, stable ph around 6.5-6.7 A fertilizer is a substance, either natural or artificial, that is applied to soil or plant tissues to provide nutrients that plants need for growth and development. Term "Organic" relates to or is derived from living matter. Organic matter refers to any material that contains carbon and was derived from living organisms. The key difference between organic minerals and organic matter lies in their origin and composition. Organic minerals are naturally occurring, inorganic compounds of carbon-based molecules, typically derived from naturally occurring biological activity. Organic matter, on the other hand, refers to the diverse pool of carbon-based compounds found in natural systems, often derived from the remains of living organisms. Organic Minerals: Definition: Naturally occurring compounds that contain carbon, in mineral form, often formed from biological activity. Organic Matter: Definition: A broad term for carbon-containing compounds found in living or dead organisms, and their residues in the environment. Is coffee grounds the most efficient use of my 5%? Probably not, but it certainly won't hurt. Organic matter is more about feeding soil microorganisms. Like a conveyor belt that converts 5% composition at a time, at most from organic matter to organic minerals the 5% adds to the 45% organic mineral bounty. How long? How long is a piece of string? Why not go above 5%? In a nutshell EC. Just don't throw in 40% organic matter into the composition; the atomic chaos from all that decay will throw off a medium and bring problems with it. The more carbon you pack into a medium, the more ability it has to retain moisture and hold charge in the form of salt nutrients, changing soil dynamics over time. EC is a shared metric of the medium by both plant processes and microorganisms that exist within the soil, Increasing available food for microorganisms increases EC dramatically, meaning less bandwidth, so to speak, is left for plant processes. Electrical Conductivity (EC) and salt content in a solution are directly related. A higher EC value indicates a higher salt concentration, and conversely, a lower EC value indicates a lower salt concentration. This relationship is key to understanding how salt concentration affects osmosis, as increased salt concentration leads to increased osmotic potential, drawing water towards the saltier solution. When microorganisms consume organic matter, it can indeed lead to an increase in soil electrical conductivity (EC). This happens because as microorganisms break down organic matter, they release dissolved nutrients and ions into the soil solution, which then increases the soil's ability to conduct electricity. Microorganisms eating organic matter can indirectly increase the Cation Exchange Capacity (CEC) of soil. As microorganisms break down organic matter, they release various substances, including nutrients and byproducts like organic acids. These substances contribute to a higher CEC by increasing the number of negatively charged sites on soil particles, which can then better retain positively charged nutrients. Osmosis will act opposite to Transpiration. Decaying high % organic matter is a very highly charged event, creating a large spike in EC which will dramatically disrupt the medium's ability to utilize water flow through transpiration by osmosis.

Why? - Coffee grounds contain nitrogen, potassium, and micronutrients. - Boost microbial life and soil structure. - Not a full fertilizer, but a useful additive in living soil. 😂

Why? They add basically nothing worthwhile to your soil mix.

Hey growmie, I have used coffee grounds mostly for my tomato plants, they seem to love it when mixed into compost or sprinkled lightly around the base. Helps with structure and a bit of N, but don’t expect it to replace real feeding. Also, always dry them out first, or you’ll end up with mold. 🤞🍀♥️

I also mixed my organic super soil & it worked out pretty well for now, maybe ask chat Gpt to help you for an all around good soil. I didn‘t add coffee grounds because of potential ph drift

Coffee grounds are a good source of nitrogen, which is essential for healthy plant growth. They also improve soil structure and drainage. However, coffee grounds are acidic, so they can lower the pH of the soil. Marijuana plants prefer a slightly acidic to neutral soil pH, so this could be beneficial. However, coffee grounds can also retain too much moisture, which can lead to root rot. Additionally, the caffeine in coffee grounds can inhibit the growth of some plants. It's important to use coffee grounds in moderation and to monitor the pH and moisture levels of the soil.
