the all aussie dribble thread!

[tdi-rick]

She's pretty. I could look past the nail!

Anyway it's somewhere to hang the shifter!

Al's back !!!!!!

 

[MCW]

so in a similar way that soil pH (power of hydrogen) will change nutrient availability in the soil

Is that like potential hydrogen

Bit of a dispute over that one but never seen any soil based text books or soil scientists calling pH "power of hydrogen", only ever seen that terminology on the web.

So what spectrum is best suited to my, um, tomatoes?

 

[splitpost]

I don't know how correct this is but just comparing apples with oranges(LEDS and Halogens)I think 80-100w in a LED has about the same lumen as a 500w Halogen flood light.........

power of hydrogen is the German phrase that pH was derived from

View attachment 302286View attachment 302287

the potential of the H+ ions in solution is what most call it
It is a measurement of H+ concentration
however that is only true for dilute solutions were the H+ is completely dissociated
were the solution is above 0.1 mol per litre it is less reliable

most use
pH=_log10[H+] is therefor wrong

true pH

pH=_log10[1/aH+] where aH is related to the hydrogen ion concentrationcH+ by the equation
aH+=fH+.cH
Where FH+ is the activity coefficient

I can go on and on I love pH

You know already !


The beauty of LED's, no where near the current draw of several hundred Plant-Lux/Grow-Lux fluro's so power consumption is no longer an indicator, so they just fly over looking for an IR signature instead

Al, I slept through qualifying last nigh t !

Must stay awake for the race tonight, must stay away for the race tonight....

Scuttlebut is that George is going to attempt to race after having his collarbone plated yesterday in Barcelona ! :msp_ohmy:
Tough little Spaniard !

 

[David (saltas)]

A really rough conversion assuming the lights are all 2800K
incandescent watts divide by 4 for a florescent
incandescent watts divide by 8 for a LED

Color temperature - Wikipedia, the free encyclopedia

the colour of sunlight changes time of day weather etc it is even different at the north and south poles

I haven't seen the quals. I'll go turn it on now.

His little nuggety mate on the Honda might not match George in raw talent but he is a threat, enough for Lorenzo to consider racing aye?

 

[lumberjackau]

Watching NASCAR atm at Sonoma, Ambrose in the lead, started second on the grid

 

[lumberjackau]

Ambrose seventh, faded towards the end, at least its a top ten finish.

Ah well another also ran if ya can't be the winner you may as well stay at home in bed at least he would have had a bit of company amongst the losers

So I am guessing you never get out of bed bob?

unfortunately bob ,if every one thought like that ,there would be no racing of any sort,what a boring world it would be.........

Thanks,now that's a simple way to figure out what I need

That's OK fellas there would be no winners if it wasn't for the also ran's and their support something the winners often forget

Heh heh. I think you may love pH just a bit too much David
While you're sitting there with your lab coat, calculator, text books, and pocket protector I'll just use my calibrated pH meter to get the same result

 

[Eccentric]

Was bored and decided to check in here to see what our mates in the southern hemisphere were up to. Wasn't expecting guys to be discussing the racing that went on last week 20 miles from my house.....................or indoor recreational "tomato" growing horticulture....:hmm3grin2orange:

 

[husq2100]

Webber 2nd and Perrelli need to pull up their socks in a hurry!

 

[Steve NW WI]

You Aussies want me to let ya know how Marcos does today, or do you want to wait till the TV signal makes it there next week?

For those of you that follow him in NASCAR, I'm one of them Earnhardt fans. Grew up watching the old man, been a Jr fan since he died, now watching the Dillon boys coming up through the ranks.

Marcos stands a good chance of winning on an oval this year if the Petty boys can put enough car under him. Dude is a flat out wheel man, I like watching him. As a Chevy guy (Holden in Aussese), I am forbidden to cheer for him though.

 

[MCW]

I am forbidden to root for him though.

Root has a completely different meaning in Australia. Wash your mouth out
