How much runoff should a guy be looking for? I fed today with 6lts and got a litre back in 5 gal pots They were dry but now i know approx how much water is needed to the point of runoff in 5 gal bags Ppm 780 6.3 goin in 1300 runoff ph 5.5 I have trays underneath and its cold here already, the woodstove is burning which helps lots with humidityI use Botanicare Pure Blend Pro fertilizers, which are 99% organic and generally do not build up in mediums like chemical fertilizer like AN’s. So, typically, with the Pro, if and when I flush, it’s generally done later in flowering if at all.
I do not water to runoff......I put just enough in before runoff begins. I don’t like runoffs since it floods the room and increases humidity to really high levels. Some mediums, like rock wool and other, runoff is necessary to reduce salt buildup. And most chemical fertilizers in any medium I would feed to runoff too. But with my nutes and medium, it’s just not necessary and more of a waste of products than anything else.
I also don’t flush very much in the end, maybe just the last 3-5 days. I often use at molasses to those flushes too, but nothing else. Make sure it’s unsulfered. Remember too, I use reverse osmosis water, with a starting point, ppm, of around 30. With that, more calmag is necessary until the last 2 weeks when it should be stop altogether as it inhibits resin production.
I’ve run out of Hydroplex now, so I’m going to do half doses of Overdrive every other watering. I want to build up P/K these next couple of weeks, as Botanicare stuff if not packed with it.
It’s always great to know the exact finishing schedule of your plants, so you can plan when to start and stop things. I generally always go to at least 70 days now, no matter what I’m growing. That seems to be the minimum for most stuff these days. Probably 68 days at the absolute earliest. Remember Soma (an old time breeder) always said, when you think they are ready, give them another week! Words to live by............
I never used trays either until i got the ones with risers. What an absolute game changer man. I now try to get about 5% runoff, i don't measure a darn thing tho. All i know is a little over a gallon goes in and a half or full solo cup of runoff comes out of my 5 gallon bags.If you are looking for runoff, I would think 10-20% that goes in and then out should be fine........but i don't like the fact that the bottom roots sit in the runoff. Roots need oxygen, not constant water. That's one of the reasons i never used trays.
If you are looking for a normal watering runoff, I would think 10-20% that goes in and then out should be fine........but i don't like the fact that the bottom roots sit in the runoff. Roots need oxygen, not constant water. That's one of the reasons i never used trays.
If you are flushing towards the end of the grow, Botanicare recommends 20-40% runoff. When i have a problem plant and want to flush it out completely, I always used the formula 2x the medium. Another words, if you use a 4 gallon pot, I'd run 8 gallons thru it, not caring how much comes out bottom. Those i would normally do in the bath tub to catch the water.
Thank you both. I have them sitting 2 inches off the trays so they have a sump so to speak. Shop vac makes quick clean up. I thought probably the bit of airflow underneath might help Im still not sure about how often to give straight ph’d water..I never used trays either until i got the ones with risers.

@Speedypete
Ideally you want to aim for 10% runoff in anything salt based imo. If you are running organic dry amendments, then youd want just a few drips of runoff that way you know you've saturated everything and arent washing nutrients and microbes away with runoff.
Unless your ph is like 4 or 10, i wouldnt worry about phing the water. I dont anyways.Im still not sure about how often to give straight ph’d water..
Im in promix and never ph my water but it comes out of the tap at like 7.0-7.2 so i figure its close enough to 6.5 that the buffer will take care of it for me.i would never add water to plants without pH adjustment first. But that depends on your soil and fertilizer, among other things.
indeed, i was getting away with out for awhile, but trying to dial in DTW or even attempt crop steering?The very first thing I always tell new grow people to do is go out and buy a good pH/ppm meter........otherwise it’s like driving a car blind. Some people can get away with it, others can use a fertilizer that automatically adjusts (I think it’s called pH perfect or something like that). But if you want to dial in your grow, it’s a necessary device IMO. But we can agree to disagree.
and no need to "ph buffer" RO water if its being DTW ? and not a res?When I add all my stuff to my reverse osmosis water, I’m anywhere between 5.7 to 6.0...........ph down I use a liquid, ph up is a powder. Not much is needed either way. Ph Down is only needed when I add too much ph up. Lol
Looking good as always!
I really like my guardian The wifi will be a game changer for folks in waterAlso, Blue Lab sent me a message that their Tri-meter now has a WiFi version, which may be helpful for some of you. The Tri-meter is what I use and I love it. I’ve had mine for years and years, and it’s just so reliable and easy to maintain .

Kinda goes without saying but for those that are legal be good.Opsec says a wifi connected grow device is a terrible idea, unless the user has the knowledge/capability to isolate it from the internet. is it novel and easy to use? possibly. is it safe or serve as a track record for when you get raided? the latter is 100% without proper precautions.
please, y'all, don't connect anything related to your grow to your wifi.
like the old DARE program. Just say no.
I bet heaps of guys even have there inkbird and infinity fans on wifi.didnt know bout that .thank fuck I havnt hooked mine up..Opsec says a wifi connected grow device is a terrible idea, unless the user has the knowledge/capability to isolate it from the internet. is it novel and easy to use? possibly. is it safe or serve as a track record for when you get raided? the latter is 100% without proper precautions.
