It's HOT

Today is not actually hot , in fact it is quite cool outside- about 17 degrees.
However it has been very hot this month in most of Eastern Australia.
The maximum here at the farm reached 36 degrees on 6th, 7th and 37 degrees on the 8th of Feb 09.
Fortunately we didn't reach 40 or 41 as they did in Canberra.It is always a little cooler here than in Canberra as we are at about 850 metres above sea level which is about 200 metres higher than Canberra.
The water in the fish tanks got up to a maximum of 28.7 on the 8th. Fish very active but it is at the top of their preferred temperature range.
And so I decided to turn off my little water heater as I didn't want to cook the fish just yet.
Unfortunately that turned out to be a mistake as you can see from the picture.
This is the 19mm black poly from the high point of the unit which was the heat collector for the pumped water from the fish tank.
I assume that the line didn't drain very well and the remaining water must have boiled in the tube creating steam and pressure which caused the blowout.
So I have had to make a third version of the heater. This one is basically the same as the last one.
I am getting faster at the manufacture but would prefer not to have to do it again. I think I will have to cover the whole unit with shade cloth if I need to turn it off due to higher ambient temps again.

The temperatures here have now dropped to the point where we have run the cooking stove at night- both to cook on and to heat our hot water in the house. Outside minimum last night was 6 degrees which is a huge change from the 23 degree minimum of the 8th.
And the fish tank has seen lows in the 15 to 16 degree range while the heater was broken. At these temps the fish are much less interested in food than they are at 25 to 27 degrees. There is no doubt in my mind that the heater is essential even at this time of year- even if just as a standby unit during the heatwave times.

My chillies are doing very well and are more than just decorative. The long skinny red ones , called Cayeene(?) are very prolific and Di has been using some in cooking. The label on the punnet said hot. And that is spot on. Only need one for a stir fry. According to Wikipedia it is hot:-
Heat: Hot (SR: 30,000-50,000)
It will be very interesting when we try the Habanero's which the label calls very hot. Considerable caution will be needed I think.
Wikipedia says of this type:-
Heat: Exceptionally Hot (SR: 100,000-350,000).
Habaneros thrive in hot weather. As with all peppers, the habanero does well in an area with good morning sun and in soil with an acidity level around 5-6 pH. The habanero should be watered only when dry. Overly moist soil and roots will produce bitter-tasting peppers.
I reckon I am doing most things wrong here- constant flushing with water, PH at 7.8. Looks like bitter peppers coming up. Will report on taste later. This assumes that enough can be consumed to give a taste other than fire!

The black pearls are also described as hot so I think we have good , if somewhat cautious, eating ahead. Interestingly some of the black pearls are bright red and some are black almost from the start while others start off green and gradually go black. The roundish ones in the 3rd picture are the black pearls. They have lovely purple flowers most of the time.
All the chillies were really put in because I couldn't resist the visual attraction of the plants.

We have had a bit of insect damage to some plants to date. The white cabbage moth is seen in the shed from time to time and is clear they are laying eggs. I don't have a picture of the moth grubs which are being a bit of a pest by making a feast of the asian greens. Mostly I don't have pictures because whenever I see one I feed it to the fish. And very much appreciated they are too.

We have also had something decimate one of the lettuce crops. It happened between my visits to the shed so I suspect it might have been grasshoppers. That is a guess as I didn't see any beasties. The affected plants are coming back so it is no big deal.
