The 2014 Greenhouse- Gina Lee

Fish in the Greenhouse

The Greenhouse this year(7th grade) and the greenhouse last year(6th grade) are basically similar but we have more fish and more materials in order to make the greenhouse more attractive and easier to handle. The systems are the same but 
they've become cleaner and more organised. The algae from last year still remains so we have to clean it but otherwise the greenhouse is in good shape. Although the greenhouse is good, some plants aren't growing well and some withered. This may be because we germinated them in autumn when the weather was getting cold and there weren't enough sun. Pumpkins, peppermints, and bok-choy are growing the best and the pumpkin is especially growing at a fast rate.

The vertical system last year

The Vertical System is a system which we made out of recycled 1liter water bottles. We stacked the bottles "on top of each other" and but pipes between them so the water flowed. Although this system doesn't require much water since it reuses the water, algae forms frequently in the pipes and the pipes sometimes gets blocked and the pots flood.The vertical system flourished with plants last year. Most of the plants in the vertical system were cucumber and basil.

Lettuce growing in this system

The grow-bed system last year

The Grow-bed system is made of clay beads we use for every system and has a total of 3large rectangular "pots" in which 2classes share one large "pot". This system can hold big plants and the cucumbers especially flourished in the grow-bed system. There are also "poles" in the back of the grow-bed system so plants like beans or pumpkins can climb and by steadied. This system is good for all types of plants and the water flow is excellent, but the plants sometimes gets unorganized, the plant leaves might get scattered, and the big plants covers the small plants and prevents it from getting sunlight.

The horizontal system last year

Bok-Choy in this system

The horizontal system is a system in which we have plastic pipes with "pot holes" evenly in them. We placed the pots(with plants) in the holes and made sure the roots reached the water flowing in the pipes. The horizontal system is an aquaponics system and uses fish to nutrient and helps the plants grow bigger and stronger. Our fish survived through the year, even during summer when we didn't take good care of them, and they don't require much money. This system is great but big plants like the pumpkin or the cucumber don't grow as well since there aren't enough space for the plants and the roots to grow.
