On the 9th, 10th and 12th of March, Adrienne from the Tauranga City Council, came to talk to us about Hydroponics and how to Hydroponically plant some dwarf beans.
She told us to bring in some 1.5L bottles for our project on Thursday.
Next she asked us a few questions about if the world changed how could we solve these problems... Population increase, ground floor pollution, air pollution and weather changes. We also talked about the 7 things that plants need to grow.
After that Adrienne showed us a Hydroponic machine called a Nutrient Film Technique. It is a long piece of house gutter with four holes in the top spaced out around 7cm gap. At the top of the gutter was a long waterproof pipe running to the bottom attached to a waterproof filter inside a container filled with water. How it works is the filter sucks the water in and it travels up the pipe. When it gets to the top it runs down the gutter watering the plants in the holes, when the water gets to the bottom it makes a waterfall into the container, making oxygen for the plants so that they can breathe.
The next day we talked about helping sick plants. There were problems of fruit farmers that we had to solve using the list of illnesses.
On Thursday we all brought in our bottles and the fun was about to begin!
She explained what we needed to do to plant some Dwarf Beans then we got started.
We paired up, I paired up with Tylah. Tylah and I first started by cutting our bottles in half. Then we went outside to get our 1 cup of Vermiculite and ½ a cup of Perlite. (Perlite is white like pearls) We put that into the top half of the bottle. Next Tylah got a 1 cup of water so we could put the nutrients (plant food) in it. With 1 teaspoon of each (A) and (B) we were able to put the seeds in. The class got 3-4 seeds to plant, you stick your small finger in and drop the seed in the holes. Then we were done.
Thankyou very much Adrienne for telling us about Hydroponics and telling us about water.
