Well that does present a problem.

You can lower the pH to 6.8 with white vinegar.

But you will need some pH test strips.
HARDDON Reviewed by HARDDON on . My little sprout! It sprouted out of the soil like 3 days ago! I've been looking at the pictures of peoples plants and theirs are a lot bigger than mine on day 3. It still looks like day 1 but a little tiny bit bigger. Whats the problem? Rating: 5
