I was wondering if I could use rainwater from a rainwater harvesting tank to fill my autopot tank (and then mix with easy2grow liquid fertiliser)? Would this have a negative impact on my plants (mostly tomatoes/cucumbers).
Hi Japers…. Rain water is perfectly fine BUT you will need to check the pH of it 1st and intermittently to ensure that the plants are receiving the correct pH in the trays….. anywhere 6.0-6.5 is generally where you need to be.
