Unfortunately ive managed to overwater my young plants when experimenting with a new substrate. They looked really droopy with grey edges and yellowing already, so i decided to restart this post for a second try germinating directly into my living soil, like im used to do it.
📆 [23rd of August]
Ive put the 2 remaining seeds directly into my homemade living soil. Exactly 72 hours later, on the 26th, one has popped up and showed their germination leafs.
I am planning to repot the plants into their "real" home after about 14 days of vegetation. That is gonna consist of 2 substrate levels in a 40l container. The bottom 2/3 is going to be a mix of peat, pumice, sand & vermiculite, the top third is gonna be a layer of my homemade living soil, which is made of 1/3 peat, 1/3 compost and 1/3 pumice 4-12mm & Spelt Husk 50%/50% (measured by volume) amended with kelp meal, sproutet bean meal, basalt rock dust, microbial mushroom biomass (chitin), oyster grit, gypsum, charcoal, bentonite and tiny amounts of bone meal & horn meal.
It is my first time growing in a (partly) nutrient poor substrate. I want to do some kind of Experiment this time, as i have not seen many growers use "hydroponic" /nutrient poor substrate paired with the "living soil" approach & organic feeding. I'm trying to boost the growth by providing plenty of oxygen and water like hydroponics does, without needing to use those mineral salt based fertilizers or frequently having to discard "old" substrate.
In my mind this idea would work similar to an "Autopot" system, where you prodive water and oxygen mainly in the bottom with some small amounts of nutrients, but feed mainly from the top by amending. Ive seen this in the "Build a soil" youtube channel.
I've set their homes up already a couple weeks ago and moistened it to let it cook together, so the living organisms could colonize the bottom subtrate before transplanting.
(Edit: Change of plans, those "homes" are gonna go to my Red Hot Cookies instead, ive just transplanted her right into an 8l pot to become a mother. Its made the same way, without the cooking together in prior part.)
The plants are going to be fed purely organic/natural material by top dressing with different amendments like fish hydrolysate, basalt, kelp, gypsum, guano and this "living soil - grow" fertilizer i've showed in the pictures.
Furthermore i am going to be using homemade nutrient ferments on cannabis for the first time. Ive already tested those on roses, tomatoes and some houseplants. (made from fish, insect, kelp, aloe vera, guano, kitchen scraps, plants etc). My goal is to additionally boost the plant growth by watering these quickly available nutrients. It should contain all the essential minerals plants need, as well as phytohormones, amino acids, vitamins, humic and fulvic acid, beneficial bacteria and fungi.
Stay hyped with me!
[Edit Week 4]
I am not as happy with the results as ive expected it. The plants are looking pretty fine and growing nicely, but i dont see any benefit compared to pure living soil yet. It almost seems like the plant is growing a little bit slower than usual and just needs to be fed more with this method, i dont see any "hydro like" boost happening... Maybe i needed to fertigate her more often and topdress more, i didnt want to try out too much though as i want to keep this plant as a mother. I dont have much time to do experiments with clones, so im probably just going to go for it as planned and hope that they will like the system in the big 40l pots. Probably going to amend the soil heavier then by topdressing more and fertilize with every watering later in veg - until mid/late flower.
