The devils lettuce makes a decent plank apparently: Hemp's potential to become major Australian agricultural industry for manufacturing building products - ABC News
Ive been a big advocate of hemp products for decades.
Its an absolutely INCREDIBLE plant.
The article is well worth reading and considering.
Is it therapeutic to cut it? hehe
How do they put together the particle board like panels - it would be glue of some sort? I wonder if its nasty like regular particle board
Also wonder which plant is more productive - hemp or bamboo. because if you are just making panels then all you want to do is grow cellulose right? The fastest growing, easiest to process would be best I suppose?
I am going to admit that I have other interests than just trees and wood. :;
The quantity of cellulose is only one variable.Quote:

We even have a native cannabis in Australia.
Hemp fibres are also very long and very tough and I would bet more so than bamboo - since the bamboo fibre length is limited to the distances between segments.
Thanks to hemp chemistry the addition of lime turns hemp into stone which is how you make hempcrete you could probably use the same process used in the production of masonite to produce hemp panels.
However glue is always a problem, but toxic glue and hemp are better than toxic glue and old-growth forests.
The day they make it legal a friend and I are going down to the park opposite the cop shop and are going to smoke a big fat roach might even share it with the boys in blue because they will be depressed on that day and that day is coming fast and I do not even smoke anything.
I however would love a low-THC cannabis leaf no bud smoothie for breakfast a very traditional breakfast in many parts of the world. Better than coffee they say.
I never knew Hemp was that strong. Bullet Proof!
Ive recently been dreaming of a machine I'd like to have involving gears and gear cutting but I don't have all the equipment for doing that in cast iron or steel. Imagine being able to go buy a sheet of 19mm hemp board and machining your own tough gears with wood working machinery! Bring the product on please!!
I just did a quick search and found this . I didn't read the whole thing. Looks interesting though.

Is hemp actually wood?
Encylopedia Britannica says that hemp - Cannabis sativa - is an annual herb. Just like parsley!
Hemp is in the Clade: Angiosperms so it shares that with trees but it sits in the Order: Rosales so it is closer to Roses than Parsley.Quote:

I played a joke on an 18-year-old friend of the family once - I brought out a bag of hops pellets told her it was cannabis and asked he if she wanted to smoke some - she smelt it and it smelt and looked good like cannabis and then I had to disappoint the kid and admit it was only hops. But the fact that it was a convincing substitute just shows you how closes these two plants are.
You can even cross-breed the hops and cannabis supposedly as they share the same ancestor.
You are always going to get the detractors those who see it as the devil's lettuce, who have bought the government, timber and petrochemical industry lies about reefer madness. But the opposition to hemp was always about money. Now there is money to be made from hemp and Nixon and Regan are DEAD and the war in Vietnam is OVER. Hemp's time in the sun will come again as it has for all of the last 10,000 years of human history.
PS. Before someone jumps down my neck for using the word cannabis that evil drug word instead of hemp - hemp is just the sanitised word used not to scare people. Botanically hemp does not exist it is just a low-THC and high CBD cultivar of cannabis sativa.
To paraphrase the great and beloved Richard Nixon "I am not a pothead". :U I do not even drink alcohol :o
The product as I understand it, is the Hemp fibre compressed into boards or beams or panels with a binder. Like the Glass in Fibreglass .Quote:

I think that you are right. Just like fibre glass or kevlar or spectra or carbon fibre - actually, hemp is a carbon fibre. Nature immitating industry!Quote:

I rather think its growth qualities are the clincher.
Its grows fast, in a huge range of conditions, needs little water, no fertiliser and its commercial uses are seemingly endless.
So it really begs the question why are we not using it farming it more, immmmm.Quote:

This, plus the development of synthetics, caused the collapse of the hemp processing industries.Quote:

Back in the 1950's and 60's I well remember:
- Hemp ropes on yachts,
- Sugar and potatoes coming in hemp bags,
- Hemp underlay under carpet,
- Hemp insulation on hot water pipes,
- Hemp caulking on wooden boats,
- Hemp used as fibre in bricks,
- I'll probably remember more.
But before it becomes viable to grow hemp you must create the industries to process and use it. That is a massive and financially risky task.
Your biggest antagonist will be the petrochemical industry - a formidable and ruthless foe.
Nylon was discovered in 1935 by DuPont. The head of DuPont was a good friend of the head of the FBI.
The next year nylon's main competition, hemp, became illegal and nylon took off.
Not a "conspiracy" just an example of big business in USA. :no:

"Hemp was banned in the US in 1937 due to a combination of factors. One of the main reasons was a massive public smear campaign and lobbying by corporate special interests who saw hemp as a threat to oil and other synthetic fibers they controlled [COLOR=var(--cib-color-foreground-accent-primary)]1. The Hearst newspaper chain, which owned vast timber holdings, was one of the most vocal opponents of hemp. They were concerned that hemp would replace wood pulp as the primary source of paper, which would have threatened their business [COLOR=var(--cib-color-foreground-accent-primary)]2[/COLOR]. Additionally, the DuPont chemical company had recently patented a new process for making synthetic fibers from petroleum, and they saw hemp as a direct competitor [COLOR=var(--cib-color-foreground-accent-primary)]2[/COLOR].[/COLOR]
The Marihuana Tax Act of 1937 was passed under the guise of regulating marijuana, but it effectively banned hemp production in the US [COLOR=var(--cib-color-foreground-accent-primary)]3. The act imposed a tax on anyone who dealt commercially in cannabis, hemp, or marijuana [COLOR=var(--cib-color-foreground-accent-primary)]3[/COLOR]. This made it too expensive for farmers to grow hemp, and it effectively ended the industry in the US [COLOR=var(--cib-color-foreground-accent-primary)]3[/COLOR].[/COLOR]
It is worth noting that hemp has been considered as a potential source of fuel for a long time. Rudolf Diesel, the inventor of the diesel engine, intended to run it on a variety of fuels, including vegetable oil and coal dust [COLOR=var(--cib-color-foreground-accent-primary)]4. In 2010, Richard Parnas, a professor of chemical engineering at the University of Connecticut, led a study which concluded that hemp produces “viable biodiesel” [COLOR=var(--cib-color-foreground-accent-primary)]4[/COLOR]. Hemp biodiesel is “ten times less toxic than table salt” and can be used to replace petroleum diesel or blended with it [COLOR=var(--cib-color-foreground-accent-primary)]4[/COLOR]. Hemp ethanol/methanol can also be used as a petrol substitute [COLOR=var(--cib-color-foreground-accent-primary)]4[/COLOR]."
