Today, we checked on our temporary set up and washed the fish tank. While doing this, my mentor realised that the leca tray we were using seemed to be quite dirty as well as that plant growth was unstable, hence with his help, we came up with the idea of integrating the "IKEA Hydroponics Kit" into the project, acting as a replacement for the present leca tray.
Here is a picture of the Hydroponics kit:
The advantages of using the new tray are that it is much easier to handle as compared to monitoring the leca kit, as well as allows for better plant growth as there is no presence of overcrowding, which boosts plant growth. However, there are only 6 pits which hold the plants (and very few leca), thus there is a limitation to the amount of the plants that can be grown.
Of course, we did sketches of the new tray and are going to modify it by drilling 2 holes, 1 in the front and 1 in the back to allow water to be transported into and out of the tray via tubes. Therefore, the latest prototype design we have right now is the same as that from the previous post, except with the tray changed to the modified hydroponics kit.
