Need help with next system

[GpsFrontier]

I always use a timer on my drip systems. There are a lot of factors that affect what on/off cycles I wind up using though. The amount of overall growing medium is probably the biggest factor. The more of it there is, the slower it will dry out (therefor longer times between cycles). Also heat and humidity. As long as the growing medium where the roots are is continually moist (not saturated), they should be fine. Just stick your fingers down into the growing medium 2 or 3 inches before the timer is set to go on to check if it's still moist or not.

how many feedings per day how long each? just as a starting point.

I would say about 30 minutes on, then the off times really depends on the factors I mentioned. You can start with 30 on and 30 off. But depending on your actual setup, and growing environment, you could go hours between on cycles. The broccoli plants I grew in 5 gallon buckets using coco chips as the growing medium (sorry, I forgot to mention the type of growing medium is a big factor as well), I was running 1 1/2 hours off, to 2 1/2 hours off, even during the hot part of the day. I have even forgotten to plug the pump back in after doing things (many times), I didn't even notice I left it unplugged until the next day, and there was no visible singes wilting at all in the plants. Now, use a different growing medium, or different size bucket, and the results wouldn't be the same.

I would say just run the drip system long enough to get the growing good and wet, then shout it off and see how long it stays moist a few inches down (during the warmest part of the day). Check it every 20 minutes or so, then say it starts to feel kind of dry after 2 hours (but the plants still are not wilting). I would set the timer for 1 1/2 hours off, that way it waters again before it gets to dry.

I also went with about 1 to 1 1/2 hour on cycles with the broccoli, but that was mostly because I was limited by the amount of on/off settings the timer had. So I stretched out the on cycles, so that I would have enough settings to work with that would last all through the day, and still have one on cycle in the middle of the night.

Thanks for the info GpsFrontier, If I go with a drip system it would be indoors under LED light so I don't think that I would loose that much moisture in the grow medium so I might be able to stretch out the feedings.

Thanks much! I'll play around with it to see what works.
