I have built my own aeroponic unit and am wondering what pH ranges are most widely used for flowering. I have been keeping it around 6 but my partner thinks that it can go as low as 4.5. Any thoughts?
i keep mine between 5.5 and 6.2. Ill let it float up to 6.2 than bring back down to 5.5 and so on so on so on. Havent had any real problems so far. Just bout to hit 4 weeks vegging
