Temperate Fruit Discussion / Re: Persimmon (Diospyros kaki) in Poland?
« on: November 16, 2019, 06:39:22 PM »
Jiro survives outdoor in full zone 6 ,to minus 24 C.I keep mein outdoor in the ground and its grafted on D Lotus.
I also have 3 D Virginiana from seed ( not hibrids) and they are the most cold hardy persimmon specie and a lot more cold hardy than D Lotus or the Kaki hibrids.
Beware of the rojo brillante because ive read thats not cold hardy as fuyu or jiro( fuyu is actually Jiro usually).
You can protect it from wind with somme cloth if you wish.

Right now I'm just running the electric milk-house style space heaters on freezing days/nights.
These heater go for about $20 each.
Most days they need no supplemental heating.
I'm not trying to maintain a tropical climate around the clock... I just want them to survive the freezing temps.
It's pretty interesting the way plants can adapt to the temp variations.
It's not unusual for sunny day temps to reach 100F+... with some night-time temps going into the 30Fs.
The plants seem to take it all in stride. They are much more flexible than you might think.
In fact... My citrus had it's best year ever. As did my Pitangatubas, Cherry of the Rio Grande, Guavas, Starfruit, Jaboticaba etc.










Nice collection of exotic fruit trees.

If its potted you can keep it in a garage or something.

It doesnt have to be that expensive.I mentioned buying one from used wich would be a lot cheaper.
And doesnt has to be Daikin or even a reverse cycle heat pump because even with a normal average air conditioner heat punp you will still save a lot of monney in a winter,maybe 2,5 cheaper than to heat with resistance heater and the air conditioner allready has( look for it) resistance heating incorporated.
I would pay 100 dollars on an air conditioner from used .
There are somme that are window mounted and they have the condenser and the fan in one piece ( no need for pipes).
Just look at efficiency rating on the label for heating az you want the most efficient to the lowest temperature possible but any ordinary air conditioner used for heating will save you a lot of monney compared to resistance heating.

Just bought somme 2x1 meter stainless steel shet to make the chimney of the stove.
It thin just 0,3 mm but i dont need to be thicker because it will be a short chimney and thickness is for structural stability.
Will be double layer of stainless steel with rockwool inbetween.
I choose it this thin because i hope it will be easyer to work with and make the bends and seams.

Nice diversity and rich market.
Prices are like in European supermarkets.

Look up Japanese moss gardens.

Propane from gas tank has 14 kw per kg heating power while wood has 4 kw per kilo.
You need 3 times more wood to carry than propane but wood its easyer to get,cheaper,safer.
Id chose wood heating over propane gas canisters anytime.
Calculate kwh price of the different fuels in your area before you decide to get a heating sistem.

Tropical Fruit Discussion / Re: winter protection for Feijoas
« on: November 13, 2019, 05:34:57 PM »
You want bees to polinate it.
Normally feijoas are polinated by birds thats why you can eat the petals of the flowers.Birds come to eat the petals and they polinate the flowers.
Somme people think the edible petals are better than the fruit and in case you dont get fruit iet,try the petals.

For polination you need another variety or a feijoa grown from seeds.The otther variety can be self polinating like Gemini wich makes small fruit but its regarded as the only true self polinated feijoa here.

Also in the first year i keep my feijoas in the greenhouse in winter because i want them to grow faster but they are cold hardy.

If id use propane to heat then i would buy an older heating central like a Viessmann 22kw that works on gas .
It doesnt loose temp memory in case of a power outage and they are dirt cheap from used @ 100 dollars.
Pipes, and one or 2 radiators or instead radiators i would go with floor( ground heating).
1 kw of gas here its 10 times cheaper than 1 kw of electric power.
Even if you use 3 times more efficient heat pump for heating ,the gas would be still at least double cheaper than that.

Feijoa are hardy to minus 16C (0f).
Ive alao read they need chilling hours or else the quality of the fruit is bad.

Here's an image from the Starplate folks:
My dome is also an icosahedron just its a 4V frequency.

Citrus General Discussion / Re: Charcoal for citrus
« on: November 12, 2019, 10:07:20 PM »
Fresh charcoal has a ph @ 8-9.Thats because of the ash content and thats why they add only 5 percent charcoal to the soil mix.
5 percent by volume not by weight since the char is soo light.

Last year i soaked about 100 litre charcoal chunks for bbq in woodvinegar...i spread them all over the garden, but now a year later it's hard to find the chunks...i don't know where they are...but it was a lot. I read somewhere that it's good to add this to the soil.
If you soaked the charcoal in wood vinnegar then thats why it dissapeared.
It reacted with the wood vinegar and probably got oxidised into CO2.
In that case you use both ,charcoal and wood vinegar for nothing as they cancel each otthers beneficial propertyes.

I remember your geodesic dome pictures that you posted on my dome greenhouse thread.
This is my dome ,picture taken by a neighbour .
I didnt finished it iet with double glazing but im cloose and im also working at the wood heating device.

Charcoal doesnt mold because its almost an inert material.
It doesnt break down by fungi like plant matter or wood and  last thousands of years.
Also ,to grow plants in charcoal only doesnt seem to be a good idea because charcoal has somme ash in it and that makes a high ph medium.
If you plant an acid loving plant like citrus in only charcoal ,it will die fast.
In the article from the first message they talk about 5 % charcoal into the soil mix.

Diospyros Lotus is termites resistant and its used as a rootstock for the asian persimmons .

Found this link.
At 0C ,the air conditioner its 3 times more efficient than resistance heating and at -10C its double efficient than resistance heating.
Even at -20C its still slightly better than resistance heating.
Off course ,this air condioned has a special feature for heating,it defrosts the cold coil peridically to keep it free of ice that can act as an insulator .
On top of that,for temperatures lover than minus 20C ,it switches to resistance heating wich it has it incorporated in it .
It only has resistance heating to protect the lifespan of the compressor.

Newer air conditioned used to heat ,like Daikin LV ,is efficient up to minus 20 C outdoor.http://www.southshorehvac.ca/cold-weather-and-your-heat-pump/
In usda zone 7 where you get a minimum of minus 18C in the coldest winter ,this heat pump will work at full efficiency.
It is more expensive than resistance heating but the electric bill will be a lot cheaper  and the air conditioner will probably pay for itself in only a winter season.
It has thermostat included in it and if you can get one from used ( second hand) then it will be dirt cheap.
Even in zone 6 and 5 its still better than resistance heating because you can save a lot of monney from electric bills until you get minus 15-20 C.
Initially i wanted to heat my greenhouse with an air conditioner( cheaper one,not Daikin) used as a heat pump and i have a big water well where i wanted to install the condenser ( the outdoor part of the air conditioner).
Because in the well there is no freezing ,it would have been 400 percent efficient all the time even if id live on zone 3-4.

In colder zones even if the efficiency drops by half you still get only half of the electric bill that you get with resistance heating.

Fructose isnt the fuel of life .
Fructose is easily converted into glucose in the organism, moreover it is used directly to synthesize fatty acids serving  as  a "fuel of life"
Fructose is as bad as alcohol for the organism.It is converted in the liver and normally the human liver can process 50 grams of glucose per day and for comparison ,40 grams of alcohol.Both ,consumed in excess cause liver damage
Glucose in pure form is readily available or from sucrose by invertase ( acid).
Worker bees fed only with fructose live 12 days while on regular diet they can live up to 80 days.
We say that fructose ,,wears,, the bees.

Look into polyembrionic seeds .Manny mango and garcinias are polyembrionic wich means they have 2 or more embrios in one seed.One is from sexual breeding and the otther/s are same exact DNA as the parent,like a grafted tree but better,on its own roots that will live longer than a grafted tree usually.

Splits in human blood.
It splits in all living things ,plants and animals not just humans because we only need the glucose wich is the fuel of life.Fructose isnt the fuel of life .
And sucrose splits easy into glucose and fructose with just a little acid ,its called invertase.
TSS its TDS actually,a measurement of electrical ressistance to guess the ammount of solids wich are conducting electricity.
Since fruits are mostly water ,the TDS is mainly from sugars.

TDS is correct and TSS is incorect because such measurement of density measures all the solids not only the sugars.There are salts and manny otther solids altough in verry small ammounts in the fruits.

Edit: measuring density with electrical devices does not work for sugars because they are non ionised.My mistake ,but still any density measurement for sugars wich is non electric should still be called TDS because its not just sugars that it measures.

Its TDS ( total disolved solids).
Fruits contain mostly fructose wich is sweeter than glucose.
Sucrose is a mix of glucose and fructose.
False again, citrus sucrose content is 2-3 times higher than that of fructose.
Sucrose is not a mix, it is a disaccharide with its physical and chemical properties different from both glucose and fructose.
Ive used bad exprimation.
What i wanted to say its that sucrose can be split into glucose and fructose.
Sucrose its @ 50 percent fructose and the rest glucose.
Results that the main carbohidrate is fructose wich is a lot sweeter than sucrose( sugar).
