Woody’s Desk

I approached this unit the way I approach most things — like a spreadsheet. Rows, columns, inputs, outputs. Turns out growing hydroponically isn’t so different from balancing a ledger. You put the right things in, you track what happens, and the numbers tell you the truth. This page is what I wish I’d had on Day One.

Section 01

The Machine

We grow on the iDOO 12-Pod Hydroponics Growing System — a countertop unit with a built-in LED grow light, a water pump, and twelve growing pods arranged in a 4-column by 3-row grid. It’s compact, quiet, and surprisingly capable.

The unit holds approximately 4 liters of water in its reservoir. That’s your growing medium, your nutrient delivery system, and your lifeline — all in one basin. Treat it accordingly.

Woody’s Note

The iDOO is not complicated. Don’t let anyone convince you otherwise. Fill the reservoir, plug it in, and let it run. The pump circulates automatically. Your job is to watch, measure, and adjust.

Section 02

The Pods & Seeds

Each pod is a small sponge-like growing medium — a little cup of potential. Before you do anything else, the pod needs to be wet. Dry pods don’t germinate. It’s that simple.

  1. Wet the pod thoroughly. Submerge it in clean water or run it under the tap until it’s saturated. Squeeze gently. It should feel heavy with moisture, not dripping.
  2. Place the pod into the growing cup. The cup sits in the pod slot on the unit. Make sure it’s seated firmly.
  3. Add your seeds. Two seeds per pod. No more. You might be tempted to add three — don’t. Two is the number. If both germinate, you thin to one later.
  4. Place the seed gently. Press each seed lightly into the top of the pod — just enough to make contact. Don’t bury it.
  5. Place the dome. The small plastic dome goes over the pod. It creates a humid microclimate that encourages germination. Don’t skip this step.

Woody’s Note

Two seeds. I tested three once. You get crowding, competition, and confusion. Two gives you a backup without the chaos. If both sprout — and they usually do — keep the stronger one. It’s not cruel. It’s math.

Section 03

Germination

Once your seeds are in and domed, your job is patience. In our experience, germination happens in 3 to 5 days. Some pods will show a sprout by Day 3. Others take the full five. Don’t panic either way.

Keep the domes on for approximately one week — or until your sprouts are clearly visible and beginning to push against the dome. The humidity matters during this stage. Removing the domes too early exposes tender seedlings to dry air before they’re ready.

StageTimeline
First sprout visibleDay 3–5
Domes come offAround Day 7
First feedingEnd of Week 1 (after domes off)
Second feeding~5 days after first
First harvest possibleWeek 5 onward

Woody’s Note

The domes are doing a job. Respect the dome. I know they look fussy, but the humidity they trap is what coaxes a seed into action. One week. Then off they come.

Section 04

Nutrients

We use General Hydroponics Flora Series — specifically FloraMicro and FloraGrow. These are two parts of a classic three-part liquid nutrient system trusted by hydroponic growers for decades. For lettuce, you don’t need the third part (FloraBloom) until much later, if at all.

We start conservatively — roughly half the recommended dose on the General Hydroponics feed chart. Young seedlings don’t need a full meal. Think of it as introducing them to solid food. Start gentle, observe, adjust.

Mixing Order — Important

Always add FloraMicro to your water first, stir, then add FloraGrow. Never mix the two concentrates together directly. Add to water, not water to nutrients.

After the first feeding, we wait approximately 5 days before the second. Watch how the plants respond before you increase dosing. Healthy, deep green color is a good sign. Yellowing or pale leaves suggest they may need more. Dark, waxy leaves can mean too much.

Woody’s Note

I’m still calibrating the feeding schedule — and I’ll be honest about that. The log is where I figure things out. We document, we observe, we adjust. That’s the whole game, really.

Section 05

pH — The Number That Matters Most

pH measures the acidity of your water. In hydroponics, it controls whether your plants can actually absorb the nutrients you’re giving them. You can add all the nutrients in the world — and if your pH is off, the plant can’t use them. It’s a locked door.

For lettuce, target a pH range of 5.5 to 6.5. That’s your window. We aim for the middle — around 6.0.

We use pH testing drops — a few drops in a water sample, compare the color to the chart. It’s analog and reliable. A digital pH meter is more precise and worth the investment if you’re serious about consistency.

pH RangeWhat It Means
Below 5.5Too acidic — nutrients lock out
5.5 – 6.5Ideal range for lettuce
Above 6.5Too alkaline — nutrients lock out

Woody’s Note

Check pH every time you add nutrients. Check it again a day later. Water changes. Nutrients change the pH when you add them. It’s not a set-and-forget situation. It’s a relationship.


From the Desk

Keep a Log. Seriously.

I keep a notepad on the desk next to the unit. Every feeding, every pH reading, every observation goes in it. Date, time, what I added, what I noticed. It takes two minutes. And when something goes wrong — or right — I know exactly what happened and when.

You don’t need a fancy system. A spiral notebook works. What you need is the discipline to write it down. The plants don’t lie, but they also don’t explain themselves. Your log does that for them.

A digital log feature is coming to the Twelve Roots app. Until then — find a notepad. Label it. Use it.

System 02

Outdoor Sunflowers

Grove Park. Mostly uncontrolled.

Woody’s Desk

The sunflower process is not complicated. It is, however, sequential. You can’t rush a seedling. You can’t rush a hardening schedule. You do things in order, you pay attention, and when the time comes, you put the plants in the ground and let the season decide the rest.

Section 01

The Setup

We start the sunflowers indoors — 15 pods in a standard seed-starting flat, under a grow light, approximately three weeks before they go in the ground. That gives us time to control the early conditions before handing them over to the weather.

Two varieties are in play: High Mowing Mammoth (pods 1–6) and High Mowing Autumn Beauty Blend (pods 7–12). A third variety — ASL Sunspot Dwarf — occupies the remaining pods. They’re not part of the competition. They’re there to watch.

The 15-pod flat is the controlled phase. Grove Park is everything after.

Woody’s Note

I use a standard 15-cell seed flat with a humidity dome and a grow light on a 16-hour cycle. Seed-starting mix, not potting soil. The mix is lighter and drains better. Potting soil compacts and holds too much moisture at this stage. Don’t substitute.

Section 02

Planting

Sunflowers are not fussy at the planting stage. They want to germinate. Your job is to give them the conditions to do it without interference.

  1. Fill each cell with moist seed-starting mix. Don’t pack it — firm it gently. You want contact without compression.
  2. Press one seed per pod, approximately 1 inch deep. No deeper. The seed needs warmth from the soil surface, not burial.
  3. Cover and firm gently. No air pockets. The seed should be surrounded by mix, not suspended in a cavity.
  4. Label each pod by number. Position matters. The draft assigns ownership by pod. Mislabeling early creates problems later.
  5. Place the humidity dome. Keep it on until the first sprout breaks through the surface.
  6. Set the grow light. 16 hours on, 8 hours off. Keep the light 6–8 inches above the flat.

Woody’s Note

One seed per pod. The instinct is to plant two as insurance. Sunflowers have a large seed — they don’t need the backup. One pod, one seed, one outcome. Cleaner data.

Section 03

Environment & Early Growth

During the indoor phase, the goal is consistency. Temperature, light duration, and moisture level should remain as stable as you can keep them. Variation is fine. Swings are not.

Water from below when possible. Bottom watering encourages deeper root development — the roots extend toward the moisture source. It also reduces the risk of damping off, which tends to travel through wet soil surfaces.

FactorTarget
Temperature65–75°F
Light16 hours/day — keep fixture 6–8 inches above seedlings
WateringDamp, not saturated — bottom water preferred
Humidity domeOn until first sprout breaks surface
Indoor phase~3 weeks (Seed Plant Day to Hardening Off)

Woody’s Note

Keep the light close. A grow light that’s too high produces leggy, weak seedlings — too much vertical stretch, not enough substance. You want compact and sturdy going into hardening. If they’re reaching, lower the light.

Section 04

Germination

Sunflowers are reliable germinators. Expect the first sprout in 7 to 10 days, sometimes sooner. Once a seedling breaks through the soil surface, remove the humidity dome. Leave it on too long and you risk damping off — a fungal condition that collapses seedlings at the soil line, usually overnight.

Any pod that hasn’t shown growth by Day 14 is noted in the log. The reserve pods exist for situations like this.

StageTimeline
First sprout visibleDay 7–10
Dome comes offWhen first sprout breaks surface
First true leavesDay 14–18
Ready to begin hardening~Day 21 (Week 3)

Woody’s Note

Sunflowers don’t need encouragement. What they need is not to be overwatered. The instinct to water more when nothing is happening is wrong. Keep the mix barely damp. They’re working.

Section 05

Hardening Off

Approximately 7 to 10 days before transplant, we begin the hardening process. Seedlings go outside for increasing periods of time each day — starting in shade, working toward full sun exposure. The goal is to condition the plant without shocking it.

  1. Days 1–2: One hour in partial shade. Back inside. Don’t rush the first exposure.
  2. Days 3–4: Two to three hours in partial shade. Light breeze is fine. Wind is not.
  3. Days 5–6: Morning hours in full sun. Shade in the afternoon. Watch for wilting.
  4. Days 7–8: Full morning and afternoon sun. Monitor for stress. Water if needed.
  5. Days 9–10: Full-day outdoor exposure. If the plants are handling it without distress, they’re ready to transplant.

Woody’s Note

Don’t rush hardening. A plant stressed by the transition takes longer to establish than one that was prepared. The extra week is not lost time. It’s invested time.

Section 06

Grove Park — In the Ground

Transplant happens around Mothers Day weekend — approximately May 12. This timing aligns the outdoor phase with the Cape Alder growing season. Soil temperature should be consistently above 50°F before you commit.

Full sun is not negotiable. Sunflowers need a minimum of 8 hours of direct sun per day. A shaded or partially shaded location will produce a weaker plant regardless of how well the indoor phase went.

FactorDetail

Transplant Day~May 12 (Mothers Day weekend)
Spacing — Mammoth18–24 inches
Spacing — Autumn Beauty12–18 inches
Sun requirement8+ hours direct sun per day
WateringDeep, 2–3× per week — avoid overhead watering
Soil pH6.0–7.5

Woody’s Note

The first week in the ground is adjustment. They may look rough. Some may droop. Roots are busy establishing. Give them water, give them sun, give them time. Don’t intervene before you have a reason to.

Section 07

What We Track

Each active pod is scored weekly using the Root Card system. Five metrics, each scored 1 to 5. Maximum 25 points per pod per week. Photo and scoring day: Tuesdays.

MetricNameWhat It Measures
HeightThe HeadlinerVertical growth from base to tallest point
Stem StrengthThe BackboneStructural integrity — ability to bear its own weight
Leaf HealthThe EngineVigor, color, and absence of damage or disease
Structural FormThe PostureOverall shape and balance of the plant
BloomThe CloserPresence, development, and quality of the flower head

Woody’s Note

The Bloom metric doesn’t activate until the flower head appears. Until then, everything is preparation. The Headliner and The Backbone tell you who’s winning early. The Closer tells you who finishes. They are not always the same plant.


From the Field

At Some Point, We Stop Controlling Things.

The hardening schedule ends. The seedlings go into the ground. The grow light gets put away.

Everything that came before — the flat, the domes, the light schedule, the temperature — was preparation. It mattered. It set the conditions. But once the plant is in the ground at Grove Park, we observe. We score. We document what actually happens.

Sun, rain, heat, pressure. The variables don’t ask permission. They just arrive.

That’s when the season actually starts.
