Will anyone please share their opinions on watering/feeding til runoff? My current understanding is you water til runoff to remove excess salts. Also I hear you want to feed frequently to keep the root zone at the optimal ppm/ec at all times. Thoughts?
You typically want run off to verify you’ve fully saturated the medium.
I feed every time.
I feed nearly every time too. I only back off if I’m starting to get salt buildup, and if that is the case, then a flush is in order. Runoff amount won’t really make a difference in salt buildup. It takes a flushing agent and/or a whole lot of water to get rid of salts.
How often you water will depend on several factors. I water only after the soil is nearly completely dried out. It is far better to under water than to over water.
What are you growing in?
I am growing in coco
I fertigate twice a day with at least 20% runoff. During Flower I up it to 3 times a day
How big are your pots? If they are bigger than 3 gals why water so much? I’ve heard other people talk about doing this. Do they dry out that fast?
My final pots are 5 gal fabric pots. They key to really unlocking coco’s potential is to never let it dry out. Some will say let it dry out. I’ve tried both methods and I can tell you the growth rate is night and day with multiple feedings per day . I’ve also had less deficiencies since I’ve changed to multiple waterings
My comments on when to water were relevant for a soil grow. Coco is different and many do what Watt-Sun mentions here.
Does that hold true for your veg too? Do you notice a big difference between plastic pots and fabric pots?
I won’t use plastic anymore. I got root bound once so I switched to fabric and will never use anything else. The combo of coco+perlite+fabric pots is an almost guaranteed way to avoid over watering and getting root bound
Def lots of different growing styles . When I first started coco everything I read said let it dry out. I did that for a few runs the @MattyBear enlightened me about daily fertigation. So I tried that and the results are plain as day
Just to clarify…you don’t let your veg dry out? Also do you notice an increase in your yields with fabric pots? Are they easy to clean?
I hear a lot of people say let your veg dry out because it encourages the roots to look for water and grow faster.
Correct, I never let my coco dry out
I don’t have a comparison on yields because I switched to fabric 1/2 way through my first grow.I don’t reuse my pots because they are cheap around here and there’s always left over root material stuck in the fabric. I prefer a fresh pot each time
Thank you so much for sharing your experience!
