I measured runoff of one plant and got 1900 after a calmag watering.
— About 10 minutes later there was more runoff so I measured it and got 900. Obviously this is a heck of a difference. Can anyone help me sort through which measure was correct?
— if I go by the 1900 number I shouldn’t feed her next time. If I use the 900 number I should.
No need to filter run off.
Channels can form in the soil from watering so what you put in, runs out quickly thru channels. This can cause an inaccurate soil ppm. In my opinion, I’d use the second number.
What nutes do you use?
Do you have a grow journal?
I just started tracking everything in a spreadsheet I created. Before it was just notes I had. Do you Have a specific question on the journal?
I’m using foxfarm trio and not a huge fan. All their reccomendations are way too hot. I’d really like a 2 part system with a chart for autos and photos. Also prefer organic. Can you recommend a better system?
So you tend to test either the entire runoff or the second half of it, but not the first half.
Thanks for the compliment. I’m a hard core dead fan.
Oh I surely can! Living no till soil. I think if you look into it, you may like it.
I started out with FF nutes. They grow great pot. Lots of pH swings and salt build up with FF nutes. I eventually learned with my happy frog soil and FF nutes, sledgehammer flushes are required. Salts build up, soil pH drops and poms go thru the roof and lock out occurs if you don’t. I got tired of all that mixing, ph’ ing and flushing. No more of that with organic living soil. I’ll find a good video for you.
Yesterday was the anniversary of Jerry’s death. I just read an interview with Bruce Hornsby talking about his last few shows with Jerry. I toured for a lot of years. I really miss those days. So many good memories and friends I made along the ride.
I didn’t take run off reading until I had at least half of the water in. I also water as slowly as possible.
I’m finding out how much better it tastes. I love it. Check out @AAA journals and also @Budbrother has taught me soooo much on living soil. Check out his grows on here too.
Here’s a few videos to hopefully help
Yes it’s necessary. It’s saponin derived from the yucca plant. I still use it for watering my living soil, because I want to use it up. With the living soil, it’s not used for removing salt build up, it’s used to help decrease the hydrophobic tendency of my peat moss in the soil.
I was just curious if you had a journal on here so I could check out your grow and girls.
Like @GreenJewels says, no need filter and the I would use the 2nd reading. I use fabric pots with primarily FF OF and I always get runoff quickly. Even from the first quart when I will be using a gallon or more. It runs down the interior side of the bag or channels. This is what I do. If I am using a gallon per plant, I will use 1/2 and discard the runoff from this first amount. Then, take the readings from the 2/2 gallon. In essence, I am using your second reading.
I really pretty much do that. Still seem to get initial run through. I water 1 qt at a time. Then next plant, then next etc. After two rounds (I only have 4 plants in a 3x3 so it isn’t terrible) I discard this run off. Then take my readings from the run off after I finish.
