30L Reservoir, How Long?

I can't always be at home to look after my aeroponic system, and was wondering how long will a 30L reservoir last with 4 plants in it, at diff stages of its life.

I am new to the art of growing and am just about to start my crop !

My aeroponic water system will be on 24/7

If anyone could share some info that'd be great. Thanks guys !


Eg. 4 Seedlings + 30L = ??Hrs
Eg. 4 Small plants + 30L = ??Hrs
Eg. 4 Large plants + 30L = ??Hrs
Eg. 4 Flowering plants + 30L = ??Hrs

Make a homemade hydroponic system cheaper less eletric around £600 (5 6 gallon resesvoir's,air pump x6 +tubing,carbon filter 4x400watt hps lights,rockwell cubes,3.5 inch net pots )

I have made this aeroponic system myself and unfortunately I'm limited on space, so I’m not sure about the multiple reservoirs.


Im sure i could do 4 plants with 1 x 400W ??

Thanks for your input
