Been trying to locate a PPM chart for Autoflowering strains and haven't had much luck. I will begin germination tomorrow, looks like I'm going to have enough room for 8 autos in my 4' x 5' area with a 600w ipower, they will be in 5 gallon buckets. I would like to fit 10 but i think it's going to be close. In particular am looking for the PPM for seedlings. I have been resting my home tap and it's in the 122-200 range it jumps around. Will this be sufficient or do I need to buy a bunch of distilled water at first? If you guys have a complete chart I would really appreciate it. thanks again everyone!
