Using rain water to fertilize

[Cewal]

Thanks for all the help, everyone.

I bought a large rainwater container from Home Depot that can be attached to the drainpipe and I am lucky to have a pipe just outside my kitchen window...but I make sure that the water flowed a minute or so before I collect it because debris from the roof can have dead leaves and debris that might decay and form bacterias to contaminate the water
