I decided to start a grow thread this year because I'm trying something new, growing in amended native soil and thought it might be fun to catalog the process of the whole grow! So here goes it.

I did all seed starts 66 planted in 4" pots on March 20th so I could choose 24 of the choicest females to go in the ground, here's the lineup,

Dark Horse Genetics
Bruce Banner BX 2.0

DJ Short
F13 Throwback
Flo
Grape Krush

Rare Dankness
501st OG
Blue Ox
Grape Ox
Longs Peak Blue
Rugburn OG

Unknown Breeder
Tahoe OG

I started by taking a couple soil sample and a well water sample, then sent them to the lab. One sample was taken at 0"-12" depth and the other at 12"-24", I wanted to see how the soil varied at different depths. Here is the results of those samples and the well water dated 2-22-2017.

0"12"

12"-24"

well water


After I received the results, which I found shocking how much nutrients were in this dry sand/clay loam, I combined and averaged the results of the two samples then calculated my amendments I needed to add. My 24 holes average between 1.75-2.25 cubic yards of soil, here's what I amended with.

Gypsum-15lbs/yd with 10lbs added to the bottom of each hole (thanks SlowN)
Soft rock phosphate-3lbs/yd
Fish bone meal-1.5lbs/yd
Ag sulfur-1.7lbs/yd
KSo4-0.25lbs/yd
Sodium tetraborate-0.04lbs/yd
MnSo4-0.44lbs/yd
ZnSo4-0.08lbs/yd
CuSo4-0.08lbs/yd
Aged steer compost (lab tested)-7.5lbs/yd
Worm castings-3lbs/yd
Alfalfa meal-1.75lbs/yd
Peat moss-2 cubic ft/yd

I also lined the bottom of the holes with all the sage I removed from the garden plot and several flakes of moldy hay on top of that before putting the amended soil back in the holes.

After that I watered in the soil once a week to let it cook for a month before retesting and getting the girls in their final home, here's the retest results from 5-23-2017

All the ladies were put in the ground by 5-23-17, sorry I don't have early on pictures but here are some pictures from June 6th and again from yesterday June 28th.

I'm sure I've missed a lot of stuff since I started this journey in February, but feel free to ask me anything and I will try to answer to the best of my ability.

Thanks to ICmag and all the love from it's members, I hope everyone enjoys the thread.

Have you considered adding calcitic lime? Gypsum is great and you need the sulfur of course but when you calcium saturation is lower than 65%, the sulfur will leach out your calcium before your magnesium. If you are able and wanting to reuse your site next year, have you considered amending the ground for different holes next year? You could add a calcitic lime and ag sulfur to drop your pH and lower your magnesium to loosen your soil maybe by the fall, it can take months for the bacteria to eat the sulfur and convert it to acid, they don't do it very effectively in the cold soil.

Plants are looking great, hoping for a big harvest for you.

cbcool the plants are looking awesome, you're going to have an incredible harvest (all that trimming going to be a pain in the ass, but its gonna be well worth it in the end). I'll be around for the show..

[cbcool]

Hey limey, I did consider ag lime at first but when I combined the 12" and 24" soil layers Ca saturation was at 68% so I opt'ed to stick with just gypsum.

I may not be in this spot next year, the wife and I are negotiating the purchase of a 40 acre lot, hopefully the deal goes through so we'll have our final resting place at least till we get old and die.


Thanks manyspliffs, trimming is always a pita around here.

Nice!! The low iron is interesting.... I thought red clay always had a lot of it.

Are you feeding at all?

Ya not this red clay, I thought the high Mn to low Fe ratio was very interesting.

Not feeding much at all, I've watered in P to try to bring it up to equal K, watered in some FeSo4, some humic/fulvic acid, and a once a month dose of LAB and FPJ made from wild mustard and tarragon.

So I guess they kind of been fed but not excessively.

I'll test the soil again in a couple weeks to see were its at before pre flowering starts.

I luv growing in the red clay at my guerilla spot. I think it brings out the pink pistils in my girls that I see so often from using that spot.

[cbcool]

I wonder if there is a mineral correlation with pistil color of if its all genetics, either way you can't go wrong with pink and purple pistols!
