led, are you saying that is a root system of a twelve day old plant? Is it a cannabis plant?
Nice results for any plant a month old or less.

12 or 13 days from seed emergence above soil line, 300ml/ little more than a pint of mix inside the pot ... 15-20 days from now it will be a foot to foot & half tall by 2' wide... repotting in next 3-4 days into 1 or 2L

The secret is the mix & how these pots sit within another container, allowing for moisture levels high enough for fine root hair growth b/w the edge of root pot & holding container... look into tree pots for conifers... I wish this site would allow for more detailed pics... it looks like aeroponics but its hose watered soil blend I make....

Thank you

Alright guys I finally got my soil test results back from spectrum. Did the k-3 test and sent in a water sample but have not yet received the results from that.

The mix is a modified cootz with buildasoil nutrient packs.

Last spring I mixed up:

1/3 pumice/some rice hulls
1/3 sunshine cspm
1/3 compost from rare earth (1/3 stutzman chicken, 1/3 oly mtn, 1/3 ewc)

Then I added what I thought was the correct amount of buildasoils cc nutrient kits. Soil was mixed well by hand.

Plants grew well during veg but showed major deficiencies during flower. Had major powdery mildew problems as well.

I'm hoping to salvage this soil to use for a small indoor grow and an outdoor raised bed. I know my numbers look pretty bad but is there any way to turn this into a decent soil? I'm guessing some gypsum might be in order lol. Thanks for any help!

I'm hoping they tested my water and will send me the results separately. I sent a check for $111 for the k-3 soil and water test. That sound right to you guys? I'll post the water results if I get them.

I also had problems with it during flower. Had a great veg (once the EC mellowed out-- it was too hot for some of the young ones and they got stunted), then they yellowed out and a couple got PM.

They send water results later.

22 days in. It's been a rough winter. But they are still trucking through it.

Water should come in the mail. It also should have cost $121 if you had your sample weighed. 51 for k3, 10 to weigh, 60 for irrigation water test.

The key lies in that EC. How can it possibly be that low?

How did the micros get that high?

The key to what though? Sorry I'm a little slow, but I definitely want to learn. I added some kelp meal during the season. Could that have pushed my micros too high? What micros specifically seem too high to you?

I also had problems with it during flower. Had a great veg (once the EC mellowed out-- it was too hot for some of the young ones and they got stunted), then they yellowed out and a couple got PM.

Thanks plants! What do you make of my soil test?

Damn, didn't realize I needed to have it weighed or that it was an extra fee.. I'm assuming they didn't weigh it then. How much is that going to change my results?

No k3 is weighed and is $51. K2 is the same but unweighed and is $41. K1 is the same unweighed and no N for $21.

Im new at this so take every word i say with a dash of salt. Zn is the only high micro but it is 1/10 of P which is right, but that is high P. I cant remember what the upper limit of zinc was but i was shooting for 60ppm so youre probably ok? Should add cu and mn. And gypsum i guess because excess cations. It willknock pH down too.

Hello,

The K3 test is $51.00 and it is an additional $10.00 for the weighing.

We do not set up accounts for small quantities. We do have an account for Mike Kraidy samples.

We can keep your credit card but we prefer not to for security reasons.

We do irrigation water testing. That cost is $60.00.

Thank you,


From Mike...

am I the only one missing something here, where do you even seen EC or TDS on his reports?

When you say low, what was it at, I don't even see it at all?

I guess you could TRY and back into it by tallying up everything that is there but we've already learned that doesn't equal the total as there are minerals adding to total EC that aren't tested for and not listed....

Are people really paying $100 + for soil tests yet they don't even have their own EC/TDS/PH pens at home, a decent combo one costs the same as a soil test....

I continue to be baffled

Under soluble salts.

I hate pens....... moving to larger industrial probes.

I saw that and I stand by Jadoka then, that number doesn't make sense based on other data

they are better than nothing at all, that is for sure..... but I hear you, I rarely use anything ever to measure anymore - once you know your inputs and they are relatively consistent its better to spend time on other things

Test new inputs, new spots etc... test at end of year to see how you did (maybe) or when things go wrong, but once you get in your grove stick to it.... Everything is always changing anyhow, tests are nothing but a moment in time, when you get them back it's too late anyhow, things have changed...

Your probes will be real time and more helpful

To me........ The dumb ass here....... Looks like the same problems.

Needs gypsum to lower Mg levels. That alone will bring everything else closer to where it needs to be. Bring that Mn up, Fe down. That PH? Needs to come down, which I believe the gypsum will also help with.........

Others chime in?

don't bring your PH down too much, the nutes that are hard to get into the plant IMO like it basically neutral - the ones that don't (micro metals not Mo though) are better delivered foliar anyhow..... It also helps keeping Fe in check which everyone seems to have TOO much off also

We all want a lot of Ca and a higher PH normally means a lot of Ca... I get many think Ca is absorbed better below 7 but not sure I agree.... The key to all this is the balance b/w Ca & Mg which just happens to be fixed with Gypsum, that's why Gypsum works, the main reason.

Keep Mg in check, K in check (fertilize when needed) and you'll be happier

You shouldn't be up at 2am posting about this type of ting in public.

did Hazy move to Maui finally or is it really 530 there... early bird, me personally, waiting to leave for the farm store to open, they keep shitty hours this time of year, 9am open, wtf !
