Indoor system. Fully controlled.
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
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.
| Spec | Detail |
|---|---|
| Pods | 12 total — arranged 4 columns × 3 rows |
| Reservoir | ~4 liters / ~1 gallon |
| Light | Full-spectrum LED, built-in arm |
| Pump | Automatic circulation, runs continuously |
| Light Schedule | 16 hours on / 8 hours off recommended |
Section 02
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.
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
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.
| Stage | Timeline |
|---|---|
| First sprout visible | Day 3–5 |
| Domes come off | Around Day 7 |
| First feeding | End of Week 1 (after domes off) |
| Second feeding | ~5 days after first |
| First harvest possible | Week 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
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 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 Range | What It Means |
|---|---|
| Below 5.5 | Too acidic — nutrients lock out |
| 5.5 – 6.5 | Ideal range for lettuce |
| Above 6.5 | Too 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
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
Grove Park. Mostly uncontrolled.
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
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.
| Spec | Detail |
|---|---|
| Pods | 15 total — 12 active, 3 spectator (Dwarf) |
| Variety A | High Mowing Mammoth — pods 1–6 |
| Variety B | High Mowing Autumn Beauty Blend — pods 7–12 |
| Growing medium | Seed-starting mix (not potting soil) |
| Indoor light | Grow light, 16 hours on / 8 hours off |
| Seed Plant Day | May 5 |
Section 02
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.
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
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.
| Factor | Target |
|---|---|
| Temperature | 65–75°F |
| Light | 16 hours/day — keep fixture 6–8 inches above seedlings |
| Watering | Damp, not saturated — bottom water preferred |
| Humidity dome | On 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
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.
| Stage | Timeline |
|---|---|
| First sprout visible | Day 7–10 |
| Dome comes off | When first sprout breaks surface |
| First true leaves | Day 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
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.
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
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.
| Factor | Detail |
|---|---|
| Location | Grove Park, Cape Alder |
| Transplant Day | ~May 12 (Mothers Day weekend) |
| Spacing — Mammoth | 18–24 inches |
| Spacing — Autumn Beauty | 12–18 inches |
| Sun requirement | 8+ hours direct sun per day |
| Watering | Deep, 2–3× per week — avoid overhead watering |
| Soil pH | 6.0–7.5 |
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
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.
| Metric | Name | What It Measures |
|---|---|---|
| Height | The Headliner | Vertical growth from base to tallest point |
| Stem Strength | The Backbone | Structural integrity — ability to bear its own weight |
| Leaf Health | The Engine | Vigor, color, and absence of damage or disease |
| Structural Form | The Posture | Overall shape and balance of the plant |
| Bloom | The Closer | Presence, 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
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.
