1800w ~ Chemdog & Sensi Star ~ SCRoG

Well hello everyone
I want to log some grows and thought what better place then ICMag...

I'm a newer grower that has done a LOT of reading...
So this legal grow is my 4th or 5th run, and it's going to be an 8 plant SCRoG..


Chamber:
1800w MH/HPS Digital (three 600w)
Three 400cfm inline blowers
6,100K BTU Window A/C
Hydrofarm 45 pint dehumidifier
Hydrogen Pro Co2 generator
Sentinel CHHC-4 environmental controler

8 of the 7gal buckets filled with a mix of Coco Coir, Perlite, and Hydroton, all mixed to equal parts.

Basically I took a 7gal bucket of Coco Coir, a 7gal bucket of Perlite, and a 7gal bucket of Hydroton, then mixed them all together. What that gave me was an extremely fast draining medium, which I'll be using synthetic organic nutrients, and treating it as a hydro top feed system.

So, each 7gal bucket's bottom is filled with 1/4" holes, and each bucket is put into a 5gal bucket that has a 3/4" ebb&flo fitting in it for drainage, and then recovery. I will be recovering, topping off, adjusting the tds & pH, and then reusing the nutrients.

Each runoff recovery bucket's use gravity to drain into a reservoir which is below in the basement..
All the sites are being hand watered 1gal of nutes every 9hrs and runoff is about 40%...
Every 30 days each site will be flushed with about 20gal of tap water (128ppm @ 6.8)...


VEG Nutrients:
Heavy 16 VEG
Organic B1
Orca
Rapidstart
Cannazym (because this is the 4th time I've used this medium)
Nirvana

After the seedling week, I started veg with 500ppm (700 scale) and @ 5.6 pH
The runoff (40% fast draining system) was around 300ppm @ 6.1.

Second week of veg they got 800ppm @ 5.6 pH...
Runoff was around 500ppm @ 6.2...


They're starting their 3rd week of veg and I'm feeding 1000ppm @ 5.8 pH...
Runoff is around 750ppm @ 6.4...



Started VEG 7 days after breaking ground




8 Days VEG




14 Days VEG





Current Environment:
Day Temp: 80-82*f
Night Temp: 73-76*f
Humidity: 55-60%
Co2: 1500-1800ppm


Just tonight I noticed some rust on the leaves, and the reason for the pH bump up..
I'm also going to add 1 teaspoon of Epson Salt per gallon of nutrient to bump up the magnesium level...

I still need to get the netting on the SCRoG frame and get it screwed down to the floor...
The netting is lacrosse netting which has 1-1/2" holes...

Oh sorry, I'm stoned out, here is the chamber itself......
The SCRoG screen is going to be 3' x 10'

I'm always interested in watching a documented Chemdog grow. Good luck with the grow!

Thanks guys

Glad to have ya all around (manly group )...

And yep Snype, I'm excited about doing Chemdog under a screen...
I've run it as lollipops but in my opinion Chemdog needs to be done in a vertical grow or under a screen if you're running all top light..
So I'm really looking forward to seeing it grow under the screen....


I'm only able to have a 7' x 11' x 8' bedroom for the next year or so...
So I figure that I'll just play a little in this small area for the next year, like with the 33% coco/perlite/hydroton mix, until we move from here...


Then we will go vertical open bulb....
Well in the wintertime anyway... lmfao

Looking very good, I would hate to be the one in charge of feeding every 9 hrs.lol You are knocking it out the park so far.

I know, it goes against just about everything we've known about coco growing.. lol
But in my mind, even though it's 33% coco, it's hydroponics, because 66% of the medium drains off rapidly..

Well the perlite retains some water and more so than the hydroton does..

I want to be able to use brew teas and still get the growth rates of say a bubble bucket, or close to it anyway...
What I'm finding, even though the organics are synthetic, the plants are booming, and pretty dam close to my hydroponic growth rates.
So I'm trying to use the coco so I can incorporate more organics for better flavors, while getting back some of the growth rates which in my personal opinion, organics fall flat on the yield itself... Kick ass in flavor, but the yields are ALWAY less over hydroponics...


So I'm just playing to see if I can get the two as close as possible, use organics and treat it more as a hydroponic system...

Unbelieveable Growth rates from Chemdog :-)

The growth rates from Chemdog is shocking... lol


17 Days Veg from seed and 12-14"es tall already....
The screen is set to 10" off the tops of the buckets, and the medium starts 2" below the rim...






Chemdog............. Into the screen already..



Sensi Star............ All 4 of them are the mostly Indica phenotype, I was hoping for at least 1 Sativa pheno... NOT...


They're still about 4-5" away from the screen, so I think I'm going to put the Chemdog on the outsides of the screen, and the 4 Sensi Star in the middle, then shorten the middle legs so the screen is 8" off the containers in the middle...




Nutrient feeding has not changed.....

Heavy 16 VEG
Organic B1
Orca
Nirvana
Rapidstart
Cannazym
Epsom Salt


1050ppm (1.5ec) @ a 5.8 pH.
Runoff 850-900ppm (1.2 to 1.3ec) @ 6.2 pH

I see no further rust spots on the Chemdog, so the bump in magnesium with the Epson Salt cured the issue..
And I used 1/2 teaspoon per gallon of nutrient that should have given me around a 15% bump in magnesium levels....

The Sensi Star is not liking all the magnesium so I'm going to have to mix 2 different soups for both strains...
One with the bump in magnesium for Chemdog and one without for Sensi Star....
