I am a beginner in all things hydroponics/gardening and have recently set up a solar powered hydroponic system to grow vegetables on my remote property 3 hours west of brisbane.

The only problem is, I only visit the property once every month and therefore will only be able to change nutrients, harvest plant, check pH levels, prune, stake etc etc once a month.

What I am wanting to ask is, WHAT VEGETABLE/HERB WOULD YOU RECOMMEND THAT I GROW FOR THIS SITUATION.

Obviously, needing a vegetable or herb that doesnt require constant care!

My digital timer/irrigation system can water the plants up to 8 times per day if necessary. The medium i am using is perlite.

Information of the climate, it is classed as sub tropical, although in winter the minimum can fall below zero for a few nights a year. The day time is generally in the 20's (even in winter) and summer days can get up to a temperature of 40deegrees, but generally stay around 30-35deegrees.
