In past 36 hours , electricity has stopped 3 times for 2/3 hours each time .
Should I + hydrogen peroxide because the air pump was off ?
Or what should I do ?
System Holds 250 litters DWC

Do the leaves look like they need calmag ?
What is 1557 on pen ? What should it be ?

gasses dissolve into water almost immediately... so the moment that air pop started running again, it was fine within moments.
now, did it droop with power off? if not, then there's plenty of o2 in the water. if electricity shuts off for 24-48-72 hours, then you have to worry a bit about the water stanating. refresh it more often in that context and should be fine, too.
you could add h2o2.. but that extra o2 would gas off in moments back to equilibrium with atmosphere. this natural equilibrium will be mostly about volume:surface area ratio.
the electricity going out for 40mins at a time is no big deal.. not the cause of the plant's stress in pictures. tweak that formula as it is out of balance.

PH bouncing aroundDWC PH bouncing wildly. Yesterday, brought PH down from 6.4 to 5.7 using Growth Technology PH Down. Today: 6.6. Nothing added in between. Only things in DWC is air stone, nutrients, roots. What causes this? Should I worry? Tap water is soft (hardness 1.6) with a PH of 7.3.Setup. Other

Setting up air cooled refactor.I've got a new air cooled light refractor, a tube like one. I've set it up such as the pic, I'm thinking of putting the extractor where it shows on the pic with the air flow going the way of the arrow, would this be OK? I can't find anything online about setting this one up.
