I have to say that I love the fact that I can be offline for a few days and come back to a terrific conversation about growing from all the terrific people who stop by.
to you all for keeping this place alive!
No news here except that it's been miserable and raining and I can't even get the plants outside to water or spray them for bugs or PM. Two days straight indoors so far...oof!
Oh, and don't forget to

Thanks Carcass! DV still looking good with more tucking and a some minor supercrops. Definitely needs to be neemed though.
And I hope it's raining up north where we get all our water from, because the stuff that comes down here just runs into the ocean!
Thanks marcus!
I know right? Getting longer and yet the plants are living in cramped chilly spaces. Next year, nothing flowers into December, and I'm only growing what fits in the tent next winter. Thanks Otter!
It doesn't look like the leaves are getting smaller, which is weird for a "sativa." And GDB has hooked you up with the link I see!
LOL! Anyone wanting to see his great indoor LOS grow, click on Otter's link.
Are we talking about ppm or pH? PPM doesn't matter in soil unless it's crazy high well water.
PPM matters more in hydro because the roots are soaking in it, but if it's not high you can probably get away without a RO filter. Just remember to factor the tap water's ppm in your EC measurements.
This! ↑
Thanks farside! I'm with you 100% on the facts, but in terms of my grow, the ProMix HP is much more part of the pH change than it would be in soil. For the detailed info, I'll link y'all
back to the post here, but the tl;dr is that peat and lime don't have the buffering capacity of soil and lime. Here's an excerpt from the manufacturer of ProMix:
"For...soil, the buffer...is much greater than formulated growing media [i.e. ProMix]
, therefore swings in pH...are less."
So my need to bump the ammoniacal N is because of the ProMix (and the length of my grows) rather than my water. In soil, the nitrate N probably wouldn't raise the pH even in grows as long as mine.
MC will by itself raise the pH of your soil because of its nitrate content, but the soil should buffer that for you. Remember that the pH of your nutrients only matters in hydro (coco included), but not in soil or soilless (ProMix/Sunshine Mix) grows.
Yes! Since you're in coco (and pH matters), it's important that the water pH be checked/adjusted just before watering rather than after mixing, especially if you have it aerating in a res. Even standing water will show a pH rise as the water interacts with the air. You've obviously figured out the compensation rate for your grow!
for all the science farside!
As farside and I have mentioned, don't sweat the pH of your nutes in your soil grows. And how well your plants do even with you going walkabout prove that point.
LOL!
Lotsa plants, lotsa water.
Anyone interested in setting up an auto-watering system (though not with automatic pH adjustment
)
@Derbybud has a tutorial on it here:
Greetings all! Here is a tutorial on how @Derbybud made his auto watering system. This is the basic information that folks are often asking him for...no reason he needs to keep repeating it. He's a busy guy :). These are his words...

One of the main selling points of our sponsor GeoFlora is that it's water only, and some folks run it successfully with only additional top dresses every 2 weeks. Though some folks find it needs more frequent application or a some help from liquid nutes. Still easier than building your own soil, that's for sure.
Not shabby at
all MG!
Damn! What's your daily step-count?
Well-made soil shouldn't have pH swing in 6 weeks, so I'm thinking what you were seeing might be issues with the MC, which were the reasons we went from loving it to just finding ways to make it work if we bought too much.
If you have enough left to make it worth using, you can buy a couple of additional nutes and blend them into a sprout-to-harvest mix using something similar to farside's or an online nutrient calculator.
@FelipeBlu has one as well. Or one of us can do the calculations for you if you're interested.
If you have the time I'd look into what folks like farside, Felipe, me, and MrSauga are doing combining plant science and nutrient blending. Ratios are the new black!
Har! I hear that low phosphorus makes all that possible.
Happy New Years All !!!
