Like digging your own grave
Oh I had serious plans for that car.



Leather retrim, roof lining was gonna be quilted.

Ramair forced cold air intake system, I was gonna make a carbon fibre feed pipe myself.

Matt black paint job.

Dayton wire wheels.

Sony system with Ground Zero speakers (It's got the Sony system and half Ground Zero but she only listens to the fucking radio).

It would have eventually been the fastest/most pimped Swift Sport around.



Job's fucked now, I'm gonna get one and do the same to mine.

Day and night temperature difference (DIF)

The term DIF refers to the difference between the average day and night temperature and is calculated as:

DIF = day temperature – night temperature

The difference between the day and night temperature can influence internode elongation and thus stem extension. Stem elongation is promoted when the day temperature is warmer than night temperature (positive DIF). During the opposite environmental conditions, when day temperature is cooler than the night temperature (negative DIF), stem elongation is inhibited. A zero DIF refers to conditions where day and night temperatures are equal.

Knowledge of how DIF affects stem elongation can be used to regulate plant height. For example, plants grown at a day temperature of 68°F and a night temperature of 50°F (+18°F DIF) will have a taller finished height than plants grown at a day temperature of 68°F and a night temperature setpoint of 77°F (−9°F DIF) ( Figure 2). An intermediate height response would occur if these plants were grown at a day and night temperature of 68°F (0 DIF).

Although using a negative DIF may sound like a great environmental tool to control plant height, this technique may not be cost-effective with the current high cost of energy for greenhouse heating. However, by understanding the DIF concept you can avoid environmental conditions that promote unwanted plant stretch. For example, in response to increasing energy costs, many growers are lowering the night temperature setpoint to save on heat. When using this strategy to reduce your energy bill, remember that you are creating a positive DIF environment and stem extension will be promoted. In addition, you may be delivering a lower average daily temperature, and thus crop timing could be delayed.

Just been in cupboard n tidied up the ducting a bit, fitted it slack when i set up again to give me room to move stuff about etc but now need the airflow more than the flexibility lol, managed to chop about 4-5ft of ducting out overall so should improve things a bit in there
Also i took some photos while I was in there so will get them up in a bit so you can see what im up against in the cupboard yorkie lol
