I go 3 days water 3 days feed. 9 litres each, temps are 24-27.As ruby said use water crystals in your dirt. Also remember ruby will water more often than you or I since SA is fucking hot. I'm on the coast of nsw so get cool and hot on and off so my plants don't use as much water. When it's 30+ i need to water my smaller pots every 1-2 days. Normally get away with every 2 min though. Also remember bigger plants need more water.
