Watering when on Vacation away from grow / 3 days

Yeah if you not got time before your away then do what you said.

It takes multiple overwaterings for it to be a problem. Now I know this isn't ideal but it's only for 3 days right So you want to get yourself a drip tray, plate whatever you have that will catch water or any run off. Dump 2-3L of water on her and pour a few 100mls into the drip tray. Not to much and after she's finished eating what she has in the soil you have a bit of back up for them. Try not your soil dry out before you go keep it moist and that. But the drip tray with water should keep her going for you for the 3 days. At worst you'll get back to thirsty plants not dead ones. Good luck pal You want to try lower your temps so the soil dries out slower

over watering is keeping saturated all the time. The amount of water you give when watering, is not over watering, it is you keep giving water before they actually need it., that is over watering

Hashy, i would if i had the time, but im leaving soon and i cant go shopping before hand- unfortunately

You could set up a simple autofeed system. Bucket, small water pump, drippers, and drip line, timer. Set it to water for while your away.
