Solar Water Pump FAQ's

For the solar option, no timer is needed.  The system will simply turn on when it’s sunny.  For coco coir this is not a problem.   For perlite and hydroton mediums, it’s best to go electric    

The pump comes with a 5 meter cord so you can maximize sun exposure to the panel.    The pump is strong enough to push water consistently above 2 meters.   

The head height (max height is actually 3.4m)  That’s alot of excess power. 

In hydroponic pumps, you always want more power.  This allows you to add flow restrictors (eg. adjustable drippers) for variable watering. 

During rainy periods, the rain will keep the garden wet for you.   The garde loves the rain.   Remember if it’s in full sun, you can’t over water it.     

If your system is under-cover and won’t get rained on, you may be better off to go with electric.   

*Battery back-ups are being tested now, but won’t be ready until late 2020.

Yes, we gaurantee the product for 6 months against any manufacturing faults.    We have dedicated Australian support.  

Simply plug the solar panel into the solar pump via an adater with 5 meter chord.    When full sun hits the panel, it activates the pump inside the reservoir.   This works reliably and effectively.
