A plant growth chamber provides a controlled environment in which plants can exist. If you are interested, you can make and calibrate a little spectrometer ( such as the Papercraft Spectrometer using a piece of cdrom) following the instructions at . Plant growth chambers or incubators allow for precise control of the. Optional: Thirdly, testing the colour spectrum is complex and beyond the scope of explaining here. You should get a result like the first figure above. Press the red stop button when you are finished. The light levels should be graphed, and you can place the phone in the chamber to measure the light. To measure light intensity, get yourself a copy of Google Science Journal and install it on your smart phone.Ĭlick the purple + button, and then click the 2nd icon along on the toolbar above the text "Add an observation". My rig raises the temperature by 3 degrees C, to 23 degrees C - that is ok. To test temperature, place your light over the hole in the esky and run it for 24h. The Wildflower Society Nursery cultivates at 8K Lux.ģ) Quality of light - the spectrum needs to be reasonably broad, and a bit like sunlight. In the open sclerophyll forest (Jarah forest, in the South West of Australia), the forest floor ranges from 1K Lux to 25 K Lux. I tested my incubator to ensure that it was suitable.ġ) Temperature (over 25 degrees and you will cook the vegetables :( we want to grow them. If the molten plastic has re -fused together, you can either cut it with a box cutter, or you can draw the nichrome wire past it again to cut and melt the plastic. When you have finished, push out the piece of plastic you have cut. Turn on the power supply and cautiously increase the voltage until you start to easily melt the plastic.ĭraw (pull) the wires along the lines you have drawn to cut out the rectangular shape. Pull the leads taut with two pair of pliers. Slide a length of nichrome wire through that hole.Ĭonnect the alligator leads to the power supply, but don't turn on yet. This is to allow light in, but to support the LED unit.ĭrill a 3mm hole in one edge of the square you have marked off. This square needs to be just smaller than the outline of your light (by at least a cm on all sides). Wear thick gardening gloves to protect against cutting/cauterising yourself with the hot wire.īegin by measuring off a square in the centre of your esky lid. Work in a well ventilated area, and do not breath any plastic fumes you may make. We will then support and seal that lid and tool it so that it is smooth and not a haven for bacteria and contamination. In this step we will put a hole through the lid of the cool box.
