first time aero grow need help

i have a single plant 5 gal aero bucket i have all the supplies i need to set it up and run it im just not sure what to set the timeer that runs the water pump i need to know how long on and how long off i have a timer with 48 settings 24 on and 24 off any help?

you need a CAP Recycle timer..
preset 1 min on 4min off is about 60$
a fully adjustable one is almost 90$.... fucking expensive,

some ppl say u can run the pumps constant but this is the correct way.. (your pumps heat up water)

Keep an eye on your water tempt or you can get root rot! (hydroxide works well to combat this)
Also get Cal/Mg supplement because those are the first to go in aeroponics! (2ml a gallon is good)
