Can anyone help,i'm using the small water farm,Does this need to go on a timer and if so what sort of time should it go on & off for?,I have 2 small plants that the leaves are starting to curl up with a yellowing to the tips and was advised it may be being watered too much, i just had it running 24/7,(Plants been in for 1 week on 18on/6off)(250W Plantastar dual spectrum,Waterfarm,)Any info i would br gratefull CHEEEEERS!!!!!!!!!!!

Try 15 minutes on, 30 mintues off I use that on my amazon, roots need to breathe and what you're doing is water logging the roots so they can't.

I have changed it to on when the light is on then off for 2hrs/on15mins off 2hrs/on15 and they are starting to look a lot happier,Do you think i should do as you say for the full 24hr cycle on 15mins off 30mins?

Assuming you're in clay pebbles, the dripper should be on 24/7 if your plants are more than a week or two old. If you're in coco, once or twice a day in veg, increasing for flower.

I would listen to GN as I have no experience with waterfarm's or clay pebbles just bubblers & amazon but if they perked up maybe try 15 minutes on / 15 minutes off. It does sound like they're waterlogged roots if they perked straight up. I'm still on my first amazon grow so can offer no more advice (I've killed all mine off and just set up again, damn pythium)

I use clay pebbles in an aquafarm.
I run the pump constantly during lights on and every 3 hours for 15 mins during lights off.
There is plenty of air provided by the pump that is forcing the soution around.
