How to water cannabis when you are away for 2 weeks?

Many greenhouses, grow stores and Amazon sell automatic plant watering systems. I have one that lets me select how many times a day it waters and how much it waters. It is powered by mains (AC) but also has battery backup in case the power goes out. The waterer came with tubing and fittings so you can water multiple plants. I water many sites around each plant depending on it's size so as much of the soil gets watered as possible. I start out by measuring how much water I give my plants at each watering. Then I put the hose of my watering system into a container and let it run so I can see how much water it puts out. Then I adjust the watering schedule so the machine provides the same amount of water that I do. I sit the plants in large plastic containers (storage totes) on top of bricks so runoff can safely drain away from the plants.

As B4rns and hempkid said, you can easy rig a self watering system. Your main problem would be your run off. So what b4rns suggested with the drain tables will stop your plants sitting in excess water.

I built a self watering system. 16 gallon tote, a 400gpm under water pump, a cheap timer. Mine feeds 2x day for 15 min. I suppose you could get a nice timer (I have one) that you can control the minutes down to 1 minute feeds. I can go away for about 4-5 days during veg cycle.

Automatic water dripping system plugged on digital timers with drain tables depending on your budget😉 Approximately 0 of equipment without the tables, easy to install 👍
