I have not seen Grodan silver.
Here we just seem to get the vertically stranded ones. Other brands will spin them in varied manners, so you can choose your water holding capacity. Dry seems to be better. However, to get such blocks, you need a proper supplier.

Getting rockwool completely out of my grows took ages, but had to be done. Perhaps you could think about containers of stuff you can use again. Expanded clay balls come in a few sizes, up to 50mm iirc. That won't hold much, though I don't think you have the table depth of decent sized final pots. You would be looking at beds.

The only thing without vertical fibers from grodan is their 12x36x3 slabs. They have horizontal fibers. And man as much as i appreciate the idea of reusable, hydroton was a bitch to clean. I basically run this room alone. Adding a whole ball cleaning session the mix doesnt sound fun. Rockwool is just my jam, ive run soil, coco, hydroton, ive spent the last 13 years with the wool i dont think im changing that anytime soon hah.

Day 12, everything is so lush and happy. Ive never had the canopy this full at this day of flower. Just trained everything down into the second trellis. Hoping i wont need a third lol.

Day 22 here, they filled the space in nicely and are still very lush and healthy. Lights are at 80%, co2 1200ppm, rh between 58-65% swinging with the condensor, leaf surface temps at 74ish degrees and ambient temp set at 76. The rooting at this stage is insane. Many of the plants have emerged roots from every slit in the slabs.

Beginning of week 5, now they will start to pack on weight. Never used a K supplement, their health is entirely related to a big bump is base feed. We were starving them apparently. This run will likely show us some morphology, yield and quality boosts. This is a pretty dreamy sight these days.

Nice to not see the K issue. I wonder if you are merely past the point of sufficiency though. You didn't change the feed profile, so it's possible another tissue sample would see similar ratios. Or didn't you increase calmag along with the base feed increase? Putting a greater gap between K and Ca, with it's antagonistic properties.
It's about now that K often starts to show, if it's actually deficient. I'm more interested in sufficient though. Having seen it be a problem before, and wanting the very best for your crop.
There is good reason to run tissue analysis again, but limit the testing (see: expenditure) to the parts of interest.

I have looked a few times, but can't find the composition of Aqua Flakes. I think it must be listed, but even looking at pics of the bottles I'm not seeing it. I presume you must have it though?

There is good reason to run tissue analysis again, but limit the testing (see: expenditure) to the parts of interest. I really disliked some of the morphology on our last run and im near certain its because of that K booster we used. It added weird nodal spacing within terminals and an overall “puffy” look. This run is much denser and tighter as they normally look.

So I only increased base feed but i decreased cal mag because i feared the antagonization. According to our last test results we had more than enough ca so i nearly eliminated it this round. I normally do 2-3ml per gallon for the first 3-4 weeks of flower. This run i did 1ml for the first 2 weeks and cut it. And the bottles themselves do say their NPK ratios but thats about it. And well see if the K deficiency shows, the past few runs we had it weeks prior to this time. I saw signs between 2-3 weeks before. Here were almost at week 6 and none to speak of so im smitten.

Even the borg couldn't stop you now. Not an alarming pointer in sight.
Hows the tester? still looking good, or did it finish the day after your photo :)

That's quite a bit to shift. My markets not what is once was either, but Christmas always keeps things moving.

The tricho jordan from beleaf is the front runner for sure simply for its uniqueness. Really butterscotch and honeyed/layered yet somehow savory nose to her. The bruce banners all seem nice but the #4 is the clear leader and the one i showed a photo of before. I also have one karma genetics headbanger going and it leans toward the sour side it seems so far. Either way they all look stable and fun so im stoked. Will be fun to see this next few weeks of progression. Lets see if we can keep em happy. At this point im backing the base down slowly. Lights are at 100% and have been this whole past week. Co2 at 1200-1250ppm. Temps around 74-76, rh between 56-60%. Shooting for a vpd around 1.1-1.2 right now, ill push that higher the last two weeks.

And yeah at this point storage is key. Once everything is dry, its burped a few times then sealed into two bags with humidipaks for potential long term storage at 45-50 degrees. This keeps them sticky and green and terpy. But yeah youre right things do typically pick up around now. Hoping for the best, its brutal.
