As I read more and more about clean energy production and learn more about the detrimental effects of urbanization, the more annoyed I get at all the blank roofs across the US. Just think about how much we could be doing if every roof actually had a purpose?

If there were solar panels, or solar air heaters or solar water heaters or green spaces on roofs across our country, we could be producing clean power, increasing individual independence and improving our air quality, water quality and environment. That’s why I was really intrigued when I saw this article on TreeHugger.con about Toronto’s green roof movement.

Have you heard of the Green Roof Movement?

The Green Roof Movement related to the transformation of roofs from wastelands to green spaces. The concept is to replace some of the green space taken up by urbanization and to offer several benefits to people, the environment and even to civil engineering challenges at the same time.

There are two basic types of green roofs – intensive and extensive. Intensive green roofs incorporate larger plants, shrubs and trees and are typically considered roof gardens. They require a great deal of maintenance and forethought because of the necessary depth of earth and the root structure management. They are usually on flat roofs as well. Extensive roof gardens employ grasses, drought tolerant species, herbs and other lighter weight plant materials. Extensive green roofs require less plantable earth, can be employed on a wider variety of roofs and tend to require far less maintenance.

The benefits of green roofs are more understood and supported in Europe, for example Germany has employed green roofs on about 10% of their buildings. Most people think a green roof will actually cause damage to their property but in truth there are several benefits to the building, to people and to our water infrastructure.

In fact, when employed properly, green roof technology can actually reduce heating bills and energy consumption, improve air quality by reintroducing green space and improve storm water management. Essentially, green roofs can absorb rainwater and put it to use, rather than merely creating heavy run-off that can cause flooding, erosion and inadvertently flush raw sewage into water supplies.

These are only a few of the benefits but because so little is known and there is so little known about green roof technologies, America is certainly slow to adapt.

I can’t wait to start implementing green technology on my roof – and you can bet that if I even built a new home, these technologies would be heavily considered in the construction.

Ok, yes you can argue that using electricity to grow things indoors is counter productive - but I’m trying to balance self sustainability and minimal energy consumption - so hear me out!

If you’re going to grow vegetables from seed anywhere that you have a freezing season, you’ll probably need a small setup with lighting for growth. If you have a sunny south facing window, you may be all set, but many people still prefer to set up a grow light for consistent growth.

Here’s a quick guide to your grow light options:

Spot Grow Bulb

Spot Grow Bulbs – Incandescent Grow Lights
Spot grow bulbs are excellent for spotlighting specific plants - like tropical plants, small groups of plants and they can be effective for starting your seeds. This means that you may want a general light source, like a fluorescent system and then use the spot grow bulbs to supplement.

Spot Grow Bulbs can be used in most standard incandescent fixtures but ideally, you’ll want a fixture that can be clipped to a specific location or hung directly where you need it. They should not be too close to your plants because they run hotter and can cause damage.

Compact Fluorescent Grow Light

Fluorescent Grow Lights
Fluorescent grow lights are well regarded for offering low heat, indoor plant growth light. You can actually get these in multiple fixtures whether hanging or even built into a plant cart. There are also compact fluorescent grow lights for maximum light and minimal energy consumption.

High output fluorescent grow lights are also well regarded and put out the most light of any fluorescent bulb for growing. You can use these for cutting propagation, seeds and seedlings, and any planting that is less than three feet tall. One of the largest benefits of using fluorescent grow lights is their low heat. They can be as close as four inches away from plants without damaging them in any way.

Metal Halide Bulb

High Intensity (HID) Grow Lights
High intensity plant grow lights are very bright and strong and can actually be used to grow small herb gardens and fruiting vegetables like tomatoes indoors. High intensity lights usually come in metal halide(MH) type which is great for natural appearance and growth and sodium (HPS) which is excellent for the fruiting and flowering cycle. In fact, metal halide grow lights are the closest to natural sunlight and they produce plants that look the most like those grown in the outdoors.

I, for one, have fluorescent tube lighting fixtures over my greenhouse trays. But I’m tempted to test the energy consumption of a metal halide system to experiment with some leafy green vegetables and fresh herbs all winter long!

I found these guys out there on the interwebs and I think their videos are AWESOME!

In this little tutorial, we learn all about vermicomposting - which is basically creating your very own, entirely self contained worm farm! You can keep this in your kitchen, or in your basement but its a great way to make more worms (which is great for your garden) and create compost (which is great for your garden) and reduce your trash (which is great for the earth!).

Also, these guys are just really funny - so enjoy the video and let me know what you think!

Our own Amy Beaudet, one of our resident experts on all things solar thermal, was recently covered in a blog post on Boston Green Scene.
