hi i got this hydro set up and im gonna be transplanting into the system in about aweek, right now i got the seedlings in rockwool and in the propogater..i haved atimer that goes off but the shortest time on it is ten minutes i was looking for 1 that goes off for only 2 to 3 minutes on every hr ..
ten minutes is way to long and probley will drown the roots i n the rockwool, so what i need is a timer that goes off for only 2 to 3 minutes on every hr and that i can raise as the plants get bigger..im in ireland..
thanks

get a digital timer, a bit more expensive about £15-20,

Get a digital timer instead


I'm sure they sell digital timers there too
I bought a few a while back from a well known high street catalogue shop called A***s or summat like that They had some offer 2 for £10 but I bet they're a lot dearer now

Hope that helps

those clay pellets you're using are really free draining so flooding the roots shouldn' be a problem (i'm presuming it's a flood and drain active recovery set up). watering twice a day to start with should also be fine (getting more frequent as they get bigger). experiment and fine tune your set up. it's all part of the fun.

thanks garvus
so if the timer goes off twice aday and for 15 minutes it be ok..thanks
