DWC air pump
ToastiesBurnedstarted grow question 2 years ago
Anyone with previous experience, what's the minimum/optimum size pump for my air bubbler? I have a cheapo single line pump, I'm assuming it's enough but not optimum. Can anyone put a number on it in cfm? Is more always better? At what point do you reach diminishing returns?

Depending on your set up you just need to be able to provide enough oxygen for your plants roots. I have used a single DWC pot and a cheapo airpump with no issues. I’d say the cheap one would have struggle to provide for anymore than two or three plants. If your doing more than one plant you can buy pumps with multiple airlines on them.
If you put your bubbler in the pot with the airpump attached and you see plenty of bubbles floating to the top you’ll be fine. I’m currently using my cheap pump to oxygenate a 30L res… Good Luck

Hope this is ok to post, looking at having a go at hydro on my next grow mainly to cut down on maintenance. What are people’s thoughts on the two systems one is stranded bubble the other one has a dripper I’m guessing will help at beginning of the grow. Thoughts please 🤙

Promix users - High runoff PPM out of the bag?For those who use promix, I'm wondering if you've noticed high outflow PPM from fresh promix? I'm using promix HPCC.
My inflow was 300
My outflow was nearly 2000
I calibrated my bluelab pen to ensure accuracy.
All numbers are on the PPM500 scale.3 years ago
