Quick update and question about PH
I am keeping a 5 gallon bucket bubbling so when I need water it is ready. The problem I am having is the ph keeps creeping back up over night. I get it dropped down to say 5.8 and the next day it will be back up to 6.8. It takes a little less to get it down each time but its been like 4 days now and it hasn't stabilized yet. Is this a problem? How should I just get it to 5.8 and then put it in right away and not give it time to go back up?
It is normal for pH to change over time, as there is gas exchange with the air (and also the bubbles you're adding).
For tap water I think your best bet is to let it sit out for at least 24 hours to evaporate the chlorine, and then pH-adjust the volume you'll use right away.
Thanks, Smokey
Have some in return for your great planning and setup.
The reason your pH keeps changing is the pH buffering effect of calcium and other mineral in your tap water. It can take several re adjustments to defeat the calcium buffering effects and stabilize your pH. Your grow area only requires the air exchanged every 5 minutes. I had kept tropical fish aquariums for more then 20 years. it can take up to 7 days with aeration to remove the chlorine added to tap water.
I have not had any issues with pH adjusting the nutrient mixture and then watering peat moss based mediums. I believe the peat moss is slightly acidic and buffers the nutrient mixture naturally.
Welcome Chronic! I was looking over your journals last night, nice work
whats up smokey!! i like your setup and you have a good idea on how to maximize your space. SCROG is def the way to go to maximize space and yield so im fully suggest it with out a doubt!!
im looking at diff LEDs and trying to land on the best one for my money and space so ill be watching yours closely to see how it does for you at harvest time!!
keep up the great work.
happy growing
Nice selection on the Plushberry! I look forward to watching them grow.
