Is rain water a good source of water?

RatmanJRstarted grow question 7y ago

Would rain water be a good source of water for indoor plants? I have always ph’d tap water; however, I have two rain tanks that I use for my outdoor tomato garden and was curious if rain water works well with cannabis. My tomatoes love it.

Rain water is the best. The ph is lower than tap water. 👍

Moldy molasses okay for compost tea/compost tea storage The new container of molasses I bought has mold growing in it. For baking that would be a throw away, but I am curious if that is still usable for making teas. I have seen some soils that add tricoderma and others, just curious? Also can a tea be stored for a week after brewing?

How early can you give it nutrients?How early can I really give it nutrients? I've read when the plant has 3 or 4 sets of leaves but in my produce-growing experience I just give it a little nutrient once it forms its first set or second if I'm lazy.
