So that's just a watering issue I've found with outdoor pots away from a water source and I don't know any way around it.ġ) how much good is one of these if you are growing outdoors away from a water source where you have to haul water to the site?Ģ) if you have a 5 gallon reservoir for water how long will it water plants for? If it's a month, that helps a lot. But if you're in pots rainwater at some point doesn't do that much good wetting the soil in the pot deep. That's not a problem if your plants are in the ground because as long as the soil around the plant gets soaked the drier soil underneath your plant will absorb the moisture around it. The problem in my experience outdoors once plants get pretty big is that even with rain the pot doesn't collect much water because the potted soil is blocked by the plant. In that case as soon as it dries out you have to refill it, hauling gallons of water to the site, right? Now, maybe you can cut off the flow so that if you are expecting a lot of rain you're saving water.
But what if you are growing in a spot that is a hike away from a water source. Obviously if this is in your backyard it's easy, you just refill the reservoir when needed. I'm really glad I found this thread, I need it.
