Getting everything formed. If the weather looks good, I'll get in next week.

So tell me what mechanism/chemistry/physics will convert hay and rabbit shot into Cec?

A few yrs ago I started with a lightweight mix at 9-10 cec. Today it is 45 and weighs 1/5 top soil. It is the absolute key to making these light medias work. No mulch or rabbit shit was ever involved. In fact unless r shit is super high N did you even move the bar on c:n. Mighta worked on field soil but?
After thinking about my previous response I realized I got caught up in your question about converting hay and manure into CEC. I wasn't planning on it breaking down that fast. When I mentioned using hay and manure I meant that the plan has been to use those as my biotic fertilizer since the CEC is low in that spot. So far everything is looking good, but it's still early in the round.

Idk i guess i wasthinking terpene production but on secon thought that paper just says terpene emission went down, not terpene content.

So i dont know what else except pathogen defense

Been having really nice results with sea stim, sea shield, rejuvenate, pepzyme, pht calcium and, both nutralive products at 1ml/gl soil drench. I used some spectrum here and there too. I ph my water to 6.5 I'm veg. It's amazing I can use so little and see results fast. So, when doing a foliar which first- photomag and some N and then cal-25 the next day or the reverse?

Thanks for stopping by Jidoka :biggrin:

I don't have a soil test since I amended the soil. I amended it with prilled CaCO3, CalPhos and Diatomaceous Earth a couple months back to let it start doing its thang and then just amended everything else a few weeks ago. And I put the plants in the ground a couple weeks ago or so.

Here was the soil test from a few months back. It's the test titled "Field":
[URL=https://www.icmag.com/ic/picture.php?albumid=72887&pictureid=1736410&thumb=1]View Image[/url]

I know it's not the best starting point for soil, but it's next to my other greenhouse and it was the best place to put it. I'm not worried about it. I can improve it as I go I'm sure. The soil test titled "Greenhse" on that page is the same soil, but it's been worked some.

As far as temps and humidity yesterday, I don't have the exact numbers inside the GH. Outside the high was 84 and the low was 69 and the humidity was probably 85-90% I'd guess. The humidity is 91% right now, just FYI. I have the Luminance greenhouse film which helps block IR light and keep it from turning into a sauna. That film has 55% light diffusion and I think 87% light transmission. It's generally pretty comfortable in there to me unless there's no wind, but then it's not that comfortable outside in the sun either. Also I keep the side vents rolled up and the roof vent rolled up. And we generally have some decent wind blowing during the day and I have horizontal air flow fans blowing 24/7. I need to get some batteries for one of my thermometer/hygrometers, but I'll put one in there once I do.

And these plants were mostly under T5HO's with some side lighting under a Spectrum King 450 watt LED. They might have got a little time directly under the LED light, which has some good intensity, before going in the GH. I don't remember. On a side note, my friend let me borrow the SK LED light perpetually. It works and I like it, but I wouldn't pay that much for a light. There's better cheaper versions of LED for less money IMO.

What's your thoughts behind your questions Jidoka?

How funny your soil analysis. That doesn't work that way. Guess Astera hasn't figured that one out yet.

What part of the soil analysis is funny?

And honestly I don't remember where I got the idea to add lime to acidic soil for pH correction and as a calcium amendment. I'm pretty sure I could find 100 links from at least as many agronomists, horticulturalists and experienced farmers that say the same thing though. I'm not saying they're correct, but if Astera did recommend to add lime to acidic soil as a calcium amendment (I don't remember if he did) then he's not alone.

So please shed a little knowledge on a brother. Why doesn't lime work as a Ca amendment in my soil? And what should I have done? Add the amount of lime I did to correct the pH and add about an equal amount of gypsum as the Ca amendment?

Of course you add calcium carbonate to an acid soil.

Adding Mg to that soil made no sense.

And running an [email protected] on all the bases is not correct. Doesn't work. Even more so when you are on an acid soil.

Did this idea come from Astera? Or was this your interpretation of Astera? Sorry to have gotten a chuckle on your dime....

Okay, I see where this is confusing. I posted up the wrong test. The correct one should be attached. If you can't see it let me know. It's for the soil titled "Field"

And I didn't mean to have the [email protected] test done on the acidic soil. I meant to have the M3 on my acidic soil and AA8.2 on the alkaline one. I messed up something on the form and ended up getting both tests done on both samples.

Lightweight...what kind of soil is that? Super low EC

You are gonna have to fertilize...that soil does not hold enough nutes to grow a crop

Old pineapple field soil in the wet tropics that's pretty much been dormant for the last 17 years. After this round I'm planning on tilling in about a yard of biochar. The low everything is part of why I've been foliar spraying so regularly. This will be an interesting first round I think, ha ha. It's going good so far. Hopefully I can keep it going
 
Is it sandy?

Oddly enough it isn't. I think it's basically degraded clay. There is some decent looking clay in the top couple inches though that I'm guessing has formed since the pineapple company moved out. I tilled it all so I'm hoping having the top couple inches mixed in will help some. I've got an updated soil sample in transit so I'll have a better idea of where to go in about a week or so.
