Depends on how big the plants are and how hot it's been but 4 or 5 days is about as long as the smaller 5s can go with a near harvest plant in them.. Beats the daily watering I was doing in regular pots.. BNW
I'm setting up a drip irrigation system for my ladies. I do this outside and it works great using timers. Inside, I'm a bit nervous in case there is a failure but taking some precautions such as reducing pressure outside before it goes inside to lower the chance of bursting. Basically making it a low pressure drip system.
