in our terrariums we have noticed lots of changes and many seeds that havee grown we have added our animals into our terrariums with the kind of environment they like our terrarium is very moist the sides are plastic and we put saran wrap ontop of the container most of our animals died we have 1 left the soil is very brown and rich it is good for the environment in the terrarium i cant wait for the plants to be fully grown the sunlight effects its growth the more sunlight out at the time the better the plants will grow the temputure has a effect on it too its different if we planted it in canada then if we planted it in california the tempeture would have a major effect evry one exept two of our seeds sprouted we dont know which seed will sprout last the seed should be covered with about 2/3 of soil the pea seed grew the best in our terrarium the clover seed in our terrarium sprouted first i would recomend you planting your seeds in your terrarium by moving little soil to put the seed in plant them in rows keep track of where there planted
