Okay I've already posted some threads about this grow already...

I will be running a modified jacks hydro 3-2-1 method in a 4-site Recirculating dwc setup AND 6 drain to waste coco pots.

Training you ask?

BIG ASS FUGGIN SCROG no really... 6x9x8 ROOM = 6x9x8 SCROG


I was almost about to do a 16 mainline per plant train but I decided to throw dwc in this run as well so I will not be setting half my room back in training methods while the other thrives.

I WILL BE AUTOMATING THIS, each reservoir will be 30 gallons (bluelab Ph adjuster and auto controller for co2. and cycle timers for dtw) - I go to my beach house every 2 weeks on the weekend for 3-4 days, and will have some remote control over this room by flower time (super excited) the DWC will get the controller most likely. (hopefully I don't need 2!) and depending on the ph swinging I might not need this at all so stay tuned.


I will be using my platinum P600 in the center on an existing 110/120 , and will be ordering 12 of Growmau5' new 100w QB pucks W/deep red and will be running them @80W each. of course after consolidating more of my panel box with tandem breakers so I can fit a 20 amp 220/240 line out for (2) meanwell 480H-c1750B's.

Im so fucking ready for this.

Crop king seeds:

White cookies
From my last run , will be occupying the 6x coco pots

And sour Diesel. Will be occupying my 4 RDWC buckets.

Cap's new 3-2-1 formula from his post
2.5 grams hydro
2.13 cal nitrate
.2 Cacl2
.095 MKP
.55 k2so4
.71 epsom salts
.005 MOST

which will give me 120-40-210-120-60 and the sulfur will be at 103.

first I will add the hydro, MKP, MOST, and K2so4 in a 5 gallon bucket of warm water and mix until dissolved. I will add this to a full res of RO water, and MIX well.

then I will add the epsom salts the same way

finally the CaNO3 and CaCl2 in the same way. "

I'll be using caps bennys and Pure essentials root enhance as well.


Just got a bunch of drip irrigation stuff, 1 and 5 gallon nursery pots ( 3.7 gal coco finisher! going for TREES) 20gph x6 outlet drip manifold, 1/4in tubing and 0-30gph bubbler emitters, pvc piping/cement, 16 and 14 inch saucers. will need to get some 2in uniseals for my dwc buckets and my sump pump to make my drip manifold run but they didnt have it in store, gotta order it online.

I have my 1 in bulkhead fittings from my old dwc I will be putting on the sidewalls of my 16in saucers to drain into a 2in pvc pipe. beats spending 200+ on a clumsy tray.
I used Jacks 3-2-1 for the last 3 flower cycles and I got excellent weight, better than in the past but the buds weren't as big. This time I am changing the PK to N balance after week 2 because I think running 3-2-1 all the way through is not quite optimum. I think the 3-2-1 isn't quite optimum for veg either. I want to try following ratios like this (NPK ratios not grams to the gallon):

NPK ratio by week:
Veg week 1: 3 - 1 - 2
Veg week 2: 3 - 1 - 2
Flo week 1 : 3 - 1 - 2
Flo week 2 : 3 - 1 - 2
Flo week 3 : 1 - 1 - 2
Flo week 4 : 1 - 1 - 2
Flo week 5 : 1 - 1 - 2
Flo week 6 : 1 - 1 - 2
Flo week 7 : 0 - 1 - 2
Flo week 8 : 0 - 1 - 2
Flo week 9 : 0 - 0 - 0
Flo week 10: 0 - 0 - 0

To do this I need to mix different ratios of the JHP to CalNit. If I did my calculations correctly it would go something like this (I just do ratios and then dilute to proper ppm for plant stage and needs):

Veg through first 2 weeks after flip:
(5 12 26) 1 part JHP
(15 0 0) 2 part JCN
1/2 part ES

Main flower stage:
(5 12 26) 2 Part JHP
(15 0 0) 1 Part JCN
1/2 part Epsom


(5 12 26) 3 parts JHP
1/2 part epsom

Clear Ph'd water


Yeah I bought the modified 3-2-1 lineup, so when I pull out cal-nit- I can add a little more cacl2, still get calcium and then Pk boost with MKP and potassium.


So far I got my Calcium chloride, cal-nit, potassium and MKP(after exploding in the box), our fulfillment center for amazon pays people to drive around delivering packages so hopefully i get more tomorrow,
