Nutrient Dosage Chart
Add nutrients every time you add water. Use the following dosage rates
3 plant Hydrogrow Reservoir holds 19 Litres of water mixed with nutrients
5 plant Hydrogrow Reservoir holds 45 Litres of water mixed with nutrients
Young plants use the Standard Dose and strongly growing plants use the Maximum Strength Dose.
After adding nutrient dose to reservoir tank allow time to mix thoroughly and test pH and adjust
if necessary.
Top-up the Reservoir as necessary, the number of top-ups required will depend on the plant’s uptake
of the solution, the more the plant uses the healthier it is. Always refi ll the Reservoir to the maximum fi ll
level (the top triangular ledge at the pump end of the Reservoir).
NEVER ALLOW THE SOLUTION TO FALL BELOW THE LEVEL OF THE PUMP.
*Use normal top-up dose on every occasion except when your plants are growing very stron gly and
are in good conditions of light and heat.
Reservoir changes
Empty and refi ll the reservoir every 3-4 weeks.
1. Switch-off PUMP and HEATER and remove delivery tube from the pump.
2. Fit the emptying tube onto the pump to drain the reservoir either to waste or collect in
buckets for use elsewhere. Fit an extension hose to emptying tube if convenient.
3. You don’t need to completely empty the reservoir but gently inclining the reservoir towards the
pump will help.
4. Replace pump and delivery tube into tray. Refi ll with clean water and nutrient dose. Young
plants use start dose, strong growing plants use full dose. Adjust pH if necessary.
5. Switch on pump and heater.

Assembly instructions for Hydrogrow NFT
Remove cut outs and place top plate in position.
The 5 plant option includes adhesive pads. Peel off the
backing on the adhesive pads and fi t to the edge of the tray.
If using the optional heater set the heater to the required
temperature (65°F to 75°F.18°C to 22°C).
Attach the suckers to the heater and secure in a horizontal
position on the base of the reservoir. THE HEATER MUST BE
SUBMERGED AT ALL TIMES. See heater instructions.
Leave the heater in the tank for 2 hours prior to planting out to
allow the water to reach the correct temperature.
1. Ensure that your electricity supply incorporates an RCCB
protection devise, or alternatively use a socket mounted
RCCB power breaker unit.
2. Ensure pump and heater are reconnected in accordance
with manufacturers instructions
3. Always switch off electricity supply before making contact
with nutrient solution in tank.
