rain water
plants grow in rain forests or in deserts.
Fresh water does actually help plants grow! (Um... heard of rain?) In fact, fresh water is the best water for plants to help them grow. Salt water can be a bit to extreme for plants, and can cause them to wilt. Salt water is great for sea plants, like sea weed or coral reef, but most plants grow better around fresh water.
i think that rain water will help it grow the best.
if a bean plant has any kind of water it will grow
Rain will better water plants because salt water has salt which will dehydrate the plant.
Tap water. Acid rain contains chemicals that are not good for plant life.
All plants need water to grow and MOST terrestrial plants need rain to provide this water. In view of this your question is meaningless.
they are easier to grow in tropical rain forests
No. If you water a plant with vitamin water the soil starts molding, the seeds do not sprout and it smells really bad! I've tried this myself at home that's how I know! yes plants will grow no plant will not grow
Yes, it gives us water to drink, bathe in, and it helps plants grow,
This depends on the type of plant you are growing. The obvious answer is enough but that may not help. Err on the dry side if in doubt.
If you are gardening outside filtered water is not necessary considering rain fall is not filtered. However if you have a greenhouse filtered water may be your option to help grow your plants bigger and brighter
