pH steady

A steady pH now of 6.4. Will have a look again tomorow and maybe give it another dose to get to 6.8. Damn cold weather means there is a lot of very slow growing in the AP system. Brocoli is the only exception, with the peas wanting to grow fast but not quite there. Days are getting longer now, and even smelt a hint of warmth in the air yesterday. I think I may need to look at building pvc pipe green houses for next winter to see if that improves growth.
