Good job!

You can quit worrying about chloramine.
For plants, even tiny seedlings, it's a non-issue.

The chloramine can kill tropical fish but it's actually beneficial for plants.
It kills bacteria and molds.

Did a side by side cloning experiment with rainwater vs. un-treated tap water with high levels of Halomethanes, chloramine, etc.

The too-pure rainwater sucked the life out of the cuttings by osmosis and left them open to infection.
The tapwater cuttings stayed healthy, rooted 2 days faster and all survived.
Lost half of the rainwater cuts and the rest were limping.

In short, if my tapwater did not have chloramine/chlorine, I'd have to add some.

Got a friend in California on well water.
He has to add bleach to his hydro tanks to keep his girls healthy.

The whole Chlorine scare is promoted by the same folks that sell overpriced reverse osmosis setups.
Go figure, yah?

With water, it's all about PH.

Aloha, and keep readin'
