Seed Group Da Best

in our group, we plant the seed in the plastic with wet tissue. we plant kidney bean and green bean, i had 2 boxes. one of them went in to a cup board and the other one, sat out side the sun.

after 4 weeks we took it out and we found out the differences. one the was out side, it was fresh, green and healthy. but one that was inside the cup board, they were weak and not fresh.

i think reason why the plant didn't grow well in the cup board was, there were not enough sun light and oxygen.
