Need a new way to water my plants.

So I have a 4x4 tent and I use soil. What would be a good way to water my plants without having to take them out every waterin?

Well, I like to do this..... could be slightly modifed for bigger pots. I just dump the desired amount of water right in the container and let the soil absorb it from the bottom, been doing it for about a year now and it works great!

long watering can, hose with spray wand,

You can spend $16 and order an eco plus sub pump. Or just use old milk jugs. Clean them out and fill them up and water.

You could create a low cost drip irrigation system by hanging a bucket high off the ground and running dripper lines from the bottom of each bucket to each container. The whole system is powdered by gravity. No electricity or timers required. You can also mix some Miracle Grow Water Storing Crystals into your medium.
