Water warm again?
Ice bottles become a daily chore. Watch water temperature and switch your chiller when it rises. Warm water and root rot are worries worth watching, even between your checks.
Home grow dosing
Stop chasing pH.
Keep your water cool.
pH up and down dosing, water temperature and alerts while you are away. Schedules run on the controller. Home Assistant built in. No subscription.
ConceptControl Freak Hydro, brought to you by Control FreakConcept: a product in development. Design, contents, and features may change. Demo values are simulated.
Between your daily checks
A grow should fit into your life.
pH drifting every day?
Stop chasing it twice a day. Dose up or down in small steps, with time to mix before the next reading.
Can’t leave for the weekend?
Something switched off with nobody noticing? See the reservoir and get alerts by push, text, email or alarm, and in Home Assistant.
How it works
Read. Dose a little. Let it mix.
For a self installed home grow with a recirculating reservoir: deep water culture, NFT or drip with return. Leafy greens, herbs and fruiting vegetables.
Watch the reservoir
pH, EC and water temperature sit alongside your level and leak readings.
Correct in small steps
pH up and pH down work within your target band. Pro adds nutrient A and B dosing.
Wait, then read again
A mixing wait separates doses. Daily limits cap the amount. A drifting or implausible reading locks dosing and raises an alarm.
What makes it different
Your grow keeps its own time.
Schedules and dosing run on the controller, so they keep going without internet. Home Assistant built in. No subscription.
More than a number on a screen.
Water on the floor, a dry reservoir or readings you can’t trust need a response. Leak and low level sensing pause the pumps and dosing. Probe checks pause dosing when the reading is suspect.
Remote notifications need a connection. Automation supplements physical checks. Keep checking your roots, tubing and reservoir.
The kit
Start with pH. Add nutrient dosing.
Starter
The daily essentials.
- Controller and Power Hub
- pH, EC and water temperature probe
- pH up and pH down pumps
- Leak sensor and reservoir low float
- Chiller outlet controlled by water temperature
Pro
Keep nutrients and water in step.
Everything in Starter, plus:
- Two nutrient pumps, A and B
- Reservoir top-off
The interactive demo shows the Pro setup with optional pump monitoring sensors fitted.
Home Assistant built in
How many apps do you open to check your grow?
Bring your reservoir and the rest of your smart home together. See readings, outlet states and alerts in Home Assistant on your home network.
The schedule stays with your grow.
Lights, feed cycles and dosing run on the controller. Your dashboard brings them into view. Every Control Freak product is a complete kit on its own, and Home Assistant can bring them together.
Options and honesty
Know what it does. Know what it needs.
Bring your own chiller.
Hydro switches your chiller by water temperature. It does not cool water by itself. Your grow system, chiller, plants and nutrients are not included.
Keep caring for your probes.
Probes need calibration, cleaning and eventual replacement. A lockout is a reason to check the probe, not permission to ignore it.
Monitoring needs a sensor.
Water pump stop detection needs an optional flow sensor. Air pump stop detection needs an optional pressure sensor. Both are shown as fitted in the demo.
Designed for home reservoirs, not commercial grow rooms. This is a product in development. The demo illustrates planned behavior and is not proof of tested hardware performance. The controller also needs power to run.
