Hi all, quick question. It will take me a day or so to get to the Hydro-Shop and I have a small problem with my 6 gal/growing Lettuce system. I have a PH of 4.5 right now and need to get it Up! What can I use for now to get it better until I get to the store.Baking Soda? I was afraid of the salt in it.
Thanks
Simon
