In your first post you said: "We encourage DIY projects. By reading info and watching videos on our site, most handy men and women can replicate easily."
In your last post: "He has been doing this for 40 years and he knows all about it including little secrets that no one will get it right even if they can replicate some aspects of the technology."
I want to see up and running greenhouses, not drawings, graphs and theories. I suspect if this was a viable option, after 40 years there would be "bubble" greenhouses all over the planet. The one thing I don't think anyone has mentioned is light permeability.
BruceM2, thank you for your most comprehensive unbiased report on this concept.
DaisyI, there are two kinds of replications: (1) you watch videos and presentations and then you say, ah, I have got it and you start replicating. (2) you do one more step further by asking questions and fully understand how it works. That is the difference between surface understanding and deep understanding. Just like everyone knows cooking and its theory, but not everyone is a good cook.
As long as you spay water in the double layer cavity, you will get better result than the single layer or double layer greenhouse filled with air only, especially in the summer time when overheating is a major problem for any greenhouses - that is why ventilation is a must. But since spraying water only works in summer time, we need to fill the cavity with bubbles. Why? To insulate so that we do not loose the heat collected during the day. As simple as that. It is crystal clear. But still, you know what I mean.
Concerning your last paragraph, I have tried to answer it on the website in the FAQ section. I bet you do not care as you are like many doubting Thomas out there, doubting about it in the first place. If everyone doubts without taking any actions, then no one will make it happen.
Like many other good things other there, the power elites tend to suppress them because they do not want us to use them. That explains why it takes so long for such a wonderful and simple invention to be presented here. It will take even longer time to have it realized if I do not take the action.
Again, whoever takes the action will benefit right away and the most.
