Max time DWC Bucket System be switched off

[Dakyne]

Good day friends,

What is the max amount of time you can have your circulation pumps switched off in a DWC bucket system, with 1 plant in each bucket, 10gal buckets. Assume you have max airation when pumps are switched off.

EDIT: During the night cycle, lights switched off.

Thx

The pumps I use have a knob on the top that allows you to adjust the power.

This could be just what you're looking for. You can just turn them down at night. It's really not a good idea to turn your air pumps off.

"Topfin" from petsmart. Do not use topfin airstones though. They have bad quality control on the stones.

Hi, thx that is a gr8 idea, unfortuantely i already have my system built. Used the equipment i had lying around. I use a 5283 gal/hour pump, so no need for airstones, it is like a seastorm in my res!! haha. And i dont think you can get an external controller to control the speed... i will go check manuals, thx for idea.

Its also not for night time when im sleeping, night time for the plants.. Also need to know this for safety measures incase something fails, then you know the time limit you have to fix it.

Just mentioned this in another thread in the hydro section. Google the Kratky method. Seems it is perfectly possible to grow in buckets with no airstones or circulation at all. Yields are down and I assume water quality would need to be monitored more closely, but there are vids of peppers and tomotoes taken to maturity with buckets of stagnant water and nutes, nothing more.

3-4 hours before % of DO reaches sub-par (50%ish) levels.... surface aeration adds more DO than airstones

Aaah thx FrozenChozen. Yeah i hate airstones and airpumps, just makes noise, generates heat... its a waste in my opinion.

this will replace any air pump in a hydro system up to about 50 gallons

some bad news then... water pumps also generate heat and noise.

waaay less of both ime...
water dampens sound,and heat..not worried about heating the res,keep in inside,if its a prob,use an external,and enclose it in a rubbermaid container,or if possible,run extra line from it remotely placed outside the grow..i really wanna redo my system,as is i have a
571gph pump hooked to a 6line divider..its loud,and hot..i remedied this by gettin a long hose,running it from the pump,thru the wall and into the grow,the heat and sound stays ina crawlspace,not so much noise as its hung from a bungee cord..i want to high pressure my buckets to save $ on one less apliance,and the little extra heat my a.c. has to battle..
