3 things you'll need before you plant

Your tower comes ready to run — it includes the net pods that hold your plants. But hydroponics grows plants in water instead of soil, so there are three things you supply yourself. All three are cheap, last a long time, and are one search away on Amazon or any garden store.

🧱

1. Rockwool cubes

This is what your seeds start in. It holds the seed and the roots in place inside the net pod (soil would clog your system). One pack lasts dozens of grows.
Get: 1 inch rockwool starter cubes — the 1" size is important so they fit snugly in your net pods.

🧪

2. Hydroponic nutrients

In hydroponics, the plant gets all of its food from the water. You add liquid hydroponic nutrients to the reservoir. Don't use regular soil fertilizer — it's not the same.
Get: a 2-part (A+B) or all-in-one hydroponic nutrient. General Hydroponics and MasterBlend are popular.

3. Seeds

Pick what you want to grow. Lettuce, basil, kale, and other leafy greens and herbs are the easiest and fastest for beginners. A single seed packet plants the whole tower.
Get: lettuce, basil, kale, or a salad-greens mix to start.

Highly recommended (optional): a cheap pH test kit + pH Down solution, and a grow light if you're growing indoors without a sunny window. We'll explain both below — you can start without them, but they make a big difference.

The 30-second overview

How your tower actually works

No soil, no mess. The pump sits in the reservoir bucket and pushes nutrient water up a tube to the top of the tower. From there, gravity pulls the water down past every plant's roots and back into the bucket — over and over. Your job is simply to keep the water topped off, the nutrients fed, and the pH in range. That's it.

Step 1

Set up your tower

1

Pick a spot

Flat, stable, with good airflow — near a sunny window, on a patio, or under a grow light. Keep it near an outlet so the pump can reach.

2

Fill the reservoir with ~5 gallons of water

Tap water is fine for most people. If you can, let it sit out overnight first (this lets chlorine evaporate). Room temperature is best.

3

Drop the pump in and connect the tubing

The pump sits fully submerged at the bottom of the bucket. Connect its tubing up to the top of the tower — that's what carries the water to the top so it can trickle down.

4

Plug it in and watch the flow

Water should reach the top and run steadily down through every pod, back into the bucket. If the flow is uneven, check the tubing isn't kinked. Let it run while you mix nutrients next.

Step 2

Mix your nutrients & water

This is the part that feels intimidating but really isn't. Two simple targets: feed the right amount, and keep the pH in range so the plants can absorb it.

1

Add nutrients to the reservoir

Follow the dosage on your bottle — it's measured per gallon. For a 5-gallon bucket, multiply by five. For young seedlings and leafy greens, start at half strength and work up. If using a 2-part (A+B), add A first, stir, then add B (never mix them together undiluted).

2

Check the pH

Plants can only "eat" the nutrients when the water is slightly acidic. Test with a pH kit and aim for the range below. If it's too high, add a few drops of pH Down, stir, and re-test.

3

You're done — let the pump circulate

The pump keeps everything mixed and oxygenated. Re-check pH every few days; it drifts as plants drink.

Don't overthink it. If you only do two things: keep the bucket topped off, and keep pH around 6. A $12 pH kit removes 90% of beginner problems. You do not need an expensive meter to start.
Step 3

Start your seeds in rockwool

You start seeds outside the tower first, then move the sprouts in. Rockwool is the little cube that holds the seed and roots.

1

Soak the rockwool first

Your 1-inch rockwool cubes are naturally high-pH, so soak them for an hour in plain water adjusted to pH ~5.5 (a splash of pH Down). This one step prevents a lot of stalled-seedling headaches. Squeeze out the excess so it's damp, not dripping.

2

Drop 1–2 seeds in each cube

Most cubes have a little hole on top. Place a seed (or two for insurance) into the hole, about 1/4" deep. Lightly pinch the top closed.

3

Keep warm, moist, and lit

Set the cubes on a tray somewhere warm. Keep them damp (never bone-dry, never soaking). A sunny windowsill or a grow light works. Most greens and herbs sprout in 3–7 days.

4

Wait for a real seedling

Once you see a sprout with its first true leaves and tiny white roots starting to poke out of the cube, it's ready for the tower. Usually 7–14 days from sowing.

Step 4

Move them into the tower

1

Set the rockwool cube into a net pod

Drop the whole cube (seedling and all) into one of the included net pods. It should sit snugly, seedling pointing up, roots pointing down.

2

Push the net pod into a tower pod hole

Press it gently into one of the 32 openings until it sits flush. Start with as many or as few as you like — even 8–10 plants is a great first grow.

3

Make sure the roots meet the water

The roots should reach into the channel where the water trickles down. Within a few days they'll find the flow and take off. That's it — you're growing.

Light

Sunlight vs grow light

☀️

Growing outdoors / by a window

Give the tower 6–8 hours of direct sun a day — a south-facing patio, balcony, or bright window. No grow light needed.

6–8 hrs sun daily
💡

Growing indoors

Add a full-spectrum LED grow light above the tower on a timer, 14–16 hours a day. Without enough light, plants get tall, pale, and weak.

14–16 hrs LED daily
Keep it going

Daily & weekly care

💧

Top off the water (every 2–3 days)

The level drops as plants drink and water evaporates. Refill so the pump always stays fully covered.

🧪

Check pH (every few days)

Aim for 5.5–6.5. Adjust with pH Down if it climbs. This is the #1 thing that keeps plants healthy.

🍶

Refresh nutrients (every 2–3 weeks)

Dump the old water, rinse the bucket, and mix a fresh batch. Top-offs in between just need a little nutrient added.

✂️

Harvest & tidy (ongoing)

Pick outer leaves as they mature and the plant keeps producing. Remove any yellow or dead leaves to keep airflow good.

Every 3–4 weeks, deep clean: empty and rinse the bucket, flush the tower with warm water, optionally wipe with diluted white vinegar to clear any algae, rinse well, then refill with fresh water + nutrients and restart the pump.
What to grow

Best crops for beginners

Fast, forgiving, and perfect for a vertical tower. Start with one or two and expand from there.

🥬

Lettuce

~30 days
🌿

Basil

~3–4 weeks
🍃

Spinach

~4–6 weeks
🥦

Kale

~4–6 weeks
🌱

Mint & herbs

Fast
🍓

Strawberries

8–12 weeks
Skip for now: big fruiting plants like tomatoes, peppers, and cucumbers. They get heavy and hungry and aren't ideal for a first tower grow. Master greens and herbs first.
If something's off

Troubleshooting

🟡 Leaves turning yellow

Usually a feeding or pH issue. Check pH first (target 5.5–6.5) — if it's off, the plant can't absorb food even when it's there. Then make sure you actually added nutrients and refreshed them in the last 2–3 weeks.

🌱 Seeds won't sprout

Most common cause: the rockwool wasn't pH-soaked, or it dried out / drowned. Keep cubes damp, warm, and not soaking, and always pre-soak rockwool to ~pH 5.5. Some seeds also just take 7+ days — be patient.

📏 Plants tall, pale, and floppy

Not enough light. Move outside into more sun, or add/lower a grow light and run it 14–16 hrs a day.

💧 Water not flowing evenly

Check the tubing for kinks, make sure the pump is fully submerged, and clear any debris from the pump intake. The pump should always sit under water.

🟢 Green slime / algae

Algae loves light hitting the water. Keep the reservoir covered/shaded, don't overfill, and do your deep clean every 3–4 weeks. A little is normal; lots means light is reaching the water.

🐛 Bugs on the leaves

Even indoor plants get the occasional aphid. Rinse them off, remove badly affected leaves, and a little neem oil spray handles most issues. Good airflow prevents most of it.

Quick answers

FAQ

Do I really need rockwool, nutrients, and seeds — they weren't in the box?
Yes — and that's normal for every hydroponic system. Your tower includes everything mechanical (tower, pump, tubing, reservoir, and the net pods). The growing media, plant food, and seeds are consumables you choose and refill yourself. All three are inexpensive and a single purchase lasts many grows.
Can I use regular potting soil or plant fertilizer?
No. Soil will clog your pump and tubing, and regular fertilizer isn't formulated for water-only growing. Use rockwool (or another clean hydroponic medium) and hydroponic-specific nutrients.
Is tap water okay?
For most people, yes. If you can, let it sit out overnight so chlorine evaporates. If you're on heavily treated or very hard water and plants struggle, switch to filtered or distilled water.
How often do I add nutrients?
Mix a full batch when you fill the reservoir, top off with a little nutrient as the level drops, and fully refresh the whole reservoir every 2–3 weeks. Always follow your bottle's dosage per gallon.
Do I have to test pH?
You can start without it, but a $10–15 pH kit is the single best thing you can add. Off-range pH is the #1 reason beginners see yellow leaves and slow growth. Aim for 5.5–6.5.
Do I need a grow light?
Only if you're growing indoors without 6–8 hours of direct sun. Outdoors or in a bright south-facing window, sunlight is plenty. Indoors, add a full-spectrum LED on a timer for 14–16 hrs/day.
How long until I can harvest?
Lettuce and fast greens are often ready ~30 days after transplanting; herbs like basil a little sooner. You can start picking outer leaves even earlier and the plant keeps producing.
Do I have to fill all 32 pods?
Not at all. Start with 8–12 plants for your first grow if you want. Just spread them out so each gets good water flow and light.
Can I leave it running 24/7?
Yes — the pump is designed to run continuously, and constant flow keeps roots oxygenated and fed. Just keep the reservoir topped off so the pump never runs dry.
