Cultivation as Calibration: The Art of Daily Tuning

Every grower knows the garden never stands still. This is true for indoor or outdoor cultivation; but it is especially true with indoor cultivation. One week the soil and the plants feel perfectly balanced and thriving; the next week, something shifts – a spike in pest pressure, VPD is off, you name it. It’s always something. Plants, microbes, and minerals exist in constant dialogue, adjusting to light, moisture, and invisible chemical cues. If you are not in tune with your garden, it is very easy to miss these moments when you need to adjust and engage skillfully with all of the changing elements. 

Cultivation, at its core, is a daily practice of tuning. It’s not perfection we’re after—it’s simply consistent presence that leads to balance and calibration.

After ten years of walking through our greenhouses or one of our indoor rooms on our farm, I can sense everything in that space and I am quietly observing and checking for equilibrium. That’s always the first step when I enter the space with the plants. Are the plants “praying” and clearly happy. What is the humidity in the room? Can you observe any visible deficiencies? I always inspect a handful of the pots and the soil closely. We know the microbes are in constant biochemical conversation with the plants, so if I can see a fungal bloom on the surface of the soil, that tells me the soil web is humming along. 

The truth is that growth itself is an act of calibration.

The Science of Balance

In cultivation, calibration actually has a precise meaning: it is the act of adjusting a system to align with optimal performance. That might mean fine-tuning pH levels, checking EC levels (electrical conductivity) of the runoff, or adjusting nutrient inputs until the plants tell us they have what they need. 

A small change can mean the difference between nutrient lockout and efficient nutrient uptake. As cultivators we have tools we can lean on to communicate with plants effectively. We rely heavily on Soil Analysis from Logan Labs in order to understand if our soil is balanced and optimized. One of the main places we look for balance is in the ratio of Calcium to Magnesium and Potassium. This golden ratio of 6:1:1 is elusive, but the main takeaway is the dominance of Calcium lives at the center of this data point. When our calcium levels are robust and on point, everything flows from there. 

When we see a ratio that is close to this, we know that most of the steering we will do for the 9 week flower cycle will be very minimal. We focus on stoking fungal growth through our Bokashi teas we bake and brew a handful of deployments to continue to try move the microbiology into a fungal dominance. Bacteria will always try to win the day, but if you give the fungi a head start and you continue to stoke them, you can move the needle in a meaningful way.  

The soil, in other words, is always speaking. Calibration is simply the practice of listening and engaging.

Healthy soil systems, like healthy humans, live in dynamic equilibrium. When we introduce inputs like humic acids, kelp, or fish hydrolysate (as we do in Soil Love), we’re not adding “food” so much as offering agronomical language – tools for communication between root and microbe, plant and environment. These bio-stimulants help the system find a balance and amplify the conversation that leads to balance.

The Philosophy of Calibration

Perfectionism dies in the garden.

The weather doesn’t cooperate, pests appear out of nowhere, irrigation lines clog, HVAC fails, lights break and something – always something – requires your attention. But the gardener who learns to calibrate, to make small corrections rather than drastic overhauls, discovers a more sustainable relationship with the garden. 

Constant calibration invites us to listen instead of control. It replaces the illusion of mastery with the practice of relationship.

When we approach cultivation as calibration, we acknowledge that our role isn’t to control a system, but to guide and harmonize with it. This is the gardener’s version of mindfulness. The act of checking soil EC in the runoff becomes a daily meditation of the patient work of observing; adjusting, and observing again becomes a form of dialogue – with the plants, the microbes and ultimately the self.

In life, just as in cultivation, the goal isn’t to hold a perfect tune; it’s to keep tuning over and over.

Applied Practice: The Grower’s Instrument

Think of your garden as a living instrument, and you’re the caretaker-musician.

• PH: Your tonal center. Keeping the PH in range and on point is foundational. 
• EC (Electrical Conductivity): The rhythm of your nutrient delivery – too slow and the plant starves, too fast and it burns. We check this every single deployment! 
• Biostimulants: Your reverb and sustain – fish hydrolysate and kelp provide microbial energy that gives the system resonance.
• Observation: Your eye and ears. Without it, calibration becomes guesswork.

A cultivator who calibrates regularly stays in conversation with the system. They don’t wait for the plant to scream in distress; they notice the early signs and they respond. And when adjustments are made, they are subtle and gradual. Avoid drastic swings; make small tweaks and when in doubt, when you’re growing in soil, trust the microbes! They usually won’t steer you wrong. 

And just as you would reach for a tuner to make sure your guitar was in tune, we rely on a “tuner” in the form of the microBiometer. If you are serious about your gardening, we would suggest you get one of these kits to test the biology in your soil. They are not too expensive (~$200) and they provide real-time data on the microbial life in your soil—fungi, bacteria, total biomass and the ratios of F:B. We highly recommend having this “tuning” instrument in your arsenal. 

The Reflection

In a world obsessed with optimization, calibration is the quieter practice. It’s the art of adjusting your course by subtle degrees rather than by big swings. It’s the gardener’s way of saying: I’m listening, I’m in tune with my plants.

So much of cultivation – and of life – is about returning to center after inevitable drift. One degree off over a long enough distance becomes miles from where you meant to be. But through small acts of recalibration, we come back into alignment again and again. The key is having systems and tools to keep things on track. 

That’s the work. That’s the fun of gardening. That’s the challenge of deep cultivation. It is never-ending and it can be frustrating at times when it feels like you’re not able to communicate effectively with the plants. I get it. But the real work is in showing up day after day, listening, tuning and adjusting. 

In cultivation, as in consciousness, balance isn’t found just once – it is maintained through daily practice. The reason why Nike has a trillion dollar slogan. 

What is the “it” in Just Do It! It’s the work. Do the work. 

Weekly Cultivation Practice:

This week, instead of focusing on optimizing your grow, try tuning in and listening to it more closely. Spend a few moments in quiet observation before making any change. Let your plants tell you what they need. The garden doesn’t demand perfection; it asks only for your attention.
