WEEK 4 (13/05/15)

The three types of plants have grown at least a little bit, that means everything is working but the part where soil wasn’t fertilized, nothing grows there. The water is creating a lot of condensation and the little pool decreases very slowly, which means they could survive with that amount of water for a long time.

PLANT	AVERAGE GROWN
Flowers (fertilized soil)	3,31 cm
Lentils (fertilized soil)	11,14 cm
Lentils (normal soil)	0 cm
Prasley (mixed soil)	3,78 cm

Oxygen had decreased a 0, 06% since last time which is very few and give us a 0, 44% but CO₂ stays at  10018 ppm (0,01%), no changes. Finnally, temperature increased to 28ºC (+2º).
