How to Grow Fresh Air — 7 Comments

  1. And now for something completely different…

    Imagine a house built with PAHS systems.

    Imagine that the air intake tubes for a PAHS house had a greenhouse full of oxygen producing plants at the air intake.


    Imagine a passivehouse. Imagine the air intake for the heat recovery ventilator sucking air from a greenhouse full of oxygen producing plants.

  2. My thoughts immediately turned to those who are elderly, sick, etc whose doctors have prescribed oxygen. That may be oxygen at night, while sleeping, or 24hrs a day.

    Imagine those people instead of being chained to noisy energy consuming oxygen separation machines, or to heavy oxygen tanks, living in homes filled with plants.

    Imagine how much cheaper it would be for the patient to not have to pay for the oxygen, or the energy bill to keep an oxygen separation machine chugging.

    Also, imagine combining other plants in a bedroom along with night-time oxygen producers, such as Lavender, which is renown for it’s relaxation inducing properties and sleep inducing effects.

    • I encourage everyone to include at least a small grow bed in their home for oxygen and food production. Either that or potted plants, windowsill gardens, etc.

    • Another tip is doing an Internet search for cinder cones plus the name of your state. This will enable you to pinpoint volcanoes with lava rock. The lava rock mines/quarries will be located next to the cinder cones. Buying direct from the mine is less expensive than buying lava rock through a middleman. Find the closest mine to your land because shipping is a major expense.

      A quick search turned up one in Goldendale in eastern WA. And there are several volcanic fields near Mt. Adams.
      And I see there’s some lava rock in Black Diamond, WA

      Note: wholesale companies are a little harder to track down than resale companies. Ask any landscape rock supplier where they get their lava rock from.

      • Thanks Doc for the advice on where to look for the rock. I really had not thought of looking using the government site. You really helped me huge on this one since I plan to use it for the build.

  3. I very much enjoyed what he had to say. I’ll try to remember to include these plants into my solarium/indoor greenhouse.

  4. I just read the video transcript at the above link. For me it was much more powerful reading the facts than trying to listen to the video. I have small, low quality speakers and it’s often difficult to hear videos. What they’ve accomplished is absolutely amazing. It’s convinced me that houses should have adequate glazing to support houseplants that will clean the air. This is especially important where the outdoor air quality is below standard.
