Feel The LOVE!!! Everybody is right; In their own world!!!
I like what krogith said, kinda...pay attention...check your rockwool to find out when it is drying up, then start with that cycle...Add/Decrease off times as you dial it in...

I think If you can afford a digital timer and decrease watering times, as opposed to increasing Off times...
You might solve your problem, because It is most likely that your are watering TOO long, not the fact that you don't have
long enough Off times. Did that make sense?

commercial drip farmers, growing tomato's,peppers, cucumber's...water in cycles of 45 seconds on every 5 minutes...this is using perlite as a medium in beto/hydro buckets

So it goes to say that since We know that r'wool holds moisture longer than perlite; It does not need to be watered as often as perlite...so conceivably, you could water for 45 seconds every 10 minutes, or every One hour...or 6 hrs. etc. Get my point? Goodluck, this was a fun thread to comment on. I gotta go tend to my garden.


I also agree with Knowmy and usually recommend adding hydroton to your r'wool cubes, to increase grower friendliness.

You heard of User friendly...Hydroton is Grower friendly...LOL.
