I have slacked on getting this grow diary going for far too long, I’m juggling a lot of things with different grows, so it may be a little weird chronologically but I will keep updating as I can, as I am taking extensive notes.
Background:
I’m running soil tests on different premixed living soils to try and find one that works best for what I want to do at scale. Essentially a collection of 4x4 and 4x8 Grassroots raised fabric beds with living soil that will be reused perpetually. Amendments will be added periodically based on soil test results.
Tests:
Each test run will consist of 2-3 runs of each soil in 2 4x4 raised fabric beds, The first run will have limited amendments to the soil, Vermiculite, azomite, and starter Microbial and bacterial innocents. Ideally the cultivars would remain the same throughout the whole test schedule, but honestly I don’t want the same 2-3 strains for the next year and a half so there will be some different things run. For me the performance of the soil via testing is more important. The following runs will light amending based on soil testing and soil structure.
Setup:
The setup is 2 4x4 raised fabric beds with approximately a yard of soil between the two of them. They will be running flowering plants perpetually 4.5 weeks apart.
Playing around with plant counts will vary from 6-12 plants per bed
Veg will happen in separate area and vary depending on plant count in beds.
The grow area is a sealed climate controlled 4x8 tent.
Co2 will be around 1200 ppm for the majority of the flowering cycle.
Lighting will be one Fluence spydr x plus light per bed, with an average peak pffd ~900 umol.
Temperature and humidity will be on a sliding scale based on VPD values
Aiming for around 1.4 kPa in flower but we’ll see, that’s still something I’m still working on.
Once the weather warms up enough for the reservoir, I will be installing Blumats automatic watering but for now its hand watering.
Feeding:
The purpose of this testing is to determine the viability of a limited feed, reusable soil medium. So the feeding will be kept to a minimum as follows.
1 topdressing of vermicompost about halfway through flower.
Foliar feedings: Up until day ~20 of flower or formation of first pistils whichever first.
Ful Power humid acid
Potassium Silicate
Kelp meal compost tea
Microbials:
Mykos mycorrhizal innoculant
Mammoth P
Versity Bacillus innoculant
Compost teas based on Kelp/EWC
IPM:
Regalia, Grandevo, Purecrop1 (Weekly foliar until week 3)
BCI , Nematodes. (soil)
Zerotol, CannControl (as needed)
The Soils.
Coast Of Maine Stonington Growers Mix.
The Soil Makers TSM Elite Living Soil.
Kis Organics Water Only Mix
Build A Soil 3.0
Hopefully this can be my small contribution to the base of knowledge here on Overgrow. One that I am extremely grateful for all it has given me. Cheers and welcome to the show!
