2. I've got 2'' of water sitting at the bottom.
3. I'd say the perlite is wet and drains well but if you're concerned that could be an issue. I was told I could run this system 3 times a day for 1 hour a piece but I was worried about recent heat in the area so I was running it all day during the first week. Maybe this is the culprit?
4. The plants are found to be drooping at all times of the day and doesn't seem to increase with the afternoon heat. They do bounce back and fourth which has made me wonder if they really are past saving.
5. Rain barrel from my roof gutter. I also strain the water with a paint strainer before mixing in nutes. It's about 40ppm.
6. 67 degrees during the day and 66 at night. (underground res)
7. Variable temps here in MD. 55-85 degrees
8. The reservoir is pretty clean. Lots of aeration and movement. I take samples from the res everyday and it looks as clear as it did the first day.
9. No smell
10. I check the ph everyday and my meter was calibrated on the 1st of May. It works.
11. I have not emptied my res yet since it has only been a week but I have been topping it off with oxidized
nutrient filled rain water.
12. I am using an air
pump with 4 stones.
Thanks for your help and interest.
