8 Automatic Plant Watering Systems To Make Herb Gardening

Whether you are planning a vacation or have a busy schedule, having an automatic plant watering system helps make daily life just a little bit easier. Some watering spikes do not come with a reservoir, so you have to supply one on your own. I like the terracotta plant waterers as they have a natural look and you can choose the long-neck bottle of your choice such as a pretty wine bottle. : EarthBox Green Container Gardening System

The Earthbox gardening system - container, stand, and caster wheels - is great for individuals who aren't able to bend over, stand up, etc. The cost is a little on the high side in my opinion, but I suppose once you factor in the re-usability aspect of it over several years, it makes sense.

System Lambda. The "marginal generator" (the plant used to meet the last MWh of demand) is the Warren plant. So, the system lambda would just be the marginal cost of the Warren plant, which is $ 30/MWh. Note the different units for total cost ($) versus average cost and marginal cost ($ /MWh). Here is an exercise that you can try on your own.
