Wiz's Chilly Grow Room, 1st Run

[wizberry]

well you see, those ac does suck up co2. I didnt know either when i used those AC untill i got my fancy co2 monitor my room was actually never 1500ppm. i wasted so much co2.

I'm sure ur right...the best AC unit would be a split unit but in an apartment unit, I just don't have the luxury of being able to mount the heat exchanger on the roof.

Aw well, I can't afford to do anything "fancy" this round...just hope to get some solid basics done this grow.

Day 17 Veg

Day 17 Veg

Got a CO2 tank and a CAP1 CO2 regulator. It's hooked up to a digital timer. Every 4 hrs, it kicks on for about 3 minutes. I'll check the CO2 levels after a day or so, w/ a co2 test kit.



Experimenting with some tubing positions. The first position is on top of the circulating fan. The second position is to the side of the fan. I think the 2nd position will spread the CO2 more down the middle of the room. Any thoughts on this?



Here's how the babies look now.



I'm trying constant drip/flow on the drippers to get more roots going faster. The top feed is going through tee'd off open 1/4 inch tubing.



So the leaves are showing slight leaf tip burn at 2.0 EC (1400ppm at .7). I'm gonna back off a bit, just add some plain water.

I've been spraying the last 3 days w/ GreenStay to get some more Mg into the plants. The plants were sprayed a week ago w/ Avid. Still have 10+ weeks for it to work out so I think it's safe.

Enzymes next!!

Day 18 Veg...Pedal to the Metal

Day 18 Veg...Pedal to the Metal

I had to readjust the ppm cuz I wanna add some enzymes but it's too concentrated already. Pumped out some nute solution, and added some RO water.

Next added some Hygrozyme about 120 ml. Running about 1.9 EC, 1300 ppm at .7



Lowered the lights by about 6 inches today, and raised the AC thermostat by 1 degree.



Can you see my cat's fat ass? She likes to hangout in this room. She likes to eat leaves though, so I can't leave her in the room unsupervised.

Also my cat loves the leaves and i let her eat some and than she sleeps ; beautiful cat btw.

Also your setup is clean and elegant

Good job

Hey tricky1,

Ya my cat likes big green leaves just as much as I do. She's just waiting for her chance to grab a big fan leaf when I'm not looking:kitty: Thx for the kind words...

Added about 100 ml of Root Xcellerator. It bumped the EC up to 2.0, about 1300 ppm (.7) pH is rock solid at 5.6 even after the addition of Xcellerator.



Took the first CO2 test today. It's up against my shopping list so my camera would focus better. It's reading about 1500ppm, I think.



Left side and Right side...they're still on 4 on, 4 off, 24/7. Growth is a little bit slower than an 18/6 routine, but it is very energy efficient. There's only 1 AC unit running now, and the thermostat was raised 1 more degree today to 69F. The actual temp on the table is about 73F or so. Hope to get to 75-76F in a few days.



The Ebb & Flo overflow fittings are plumbed together and drain into the small res. The chiller is running at 69F and doesn't come on very often.



A few days after topping... I lowered the lights again today. About 36" away from the tops. I'd like to get them to 24" away for the last week of veg. Think they can take more?

Geez where to start!!!

It looks similar to my system but bigger!!! Thats kickass!!!

Each Chilly Box measures 40 x 60 inches and holds about 30 gallons of nutrient solution. The nutrient temp stays at 68F with or without a chiller, surprisingly.

hehehe one of the secretes of the magic trays!!! NICE...

Everything is looks really good here man.. The little gals you got going on DONT need that high of an EC.. Once they start to take off(many roots) in the water then you can rise it.. but i wouldn't go over 800ppm with plants that size.. The root mass should be fine that way as well.. I have found to much top feeding results in a root bound upper netpot at near end of crop, be careful how much top feeding you do, it makes a difference later on in the crop.. Its a fine line you want the roots to fill out in the netpot, but not overgrow it.less top feeding results in more directional downward root growth.

Far as pruning is concerned you said you were going for trees right?? So let um fill out. dont prune anything right now. more leaves and branches the faster she will grow. prune 2 weeks before flower, up to 2 weeks after flower.. Knock any small shit off the bottom and focuse on four or more stalks (your strongest ones)

CO2 is a waste of time right now she doesnt have enough girth to utilize it at the moment.. You will know when its time to kick it in again..

Peace Wizberry!! I got this one tagged!

Is that why under current stop selling their system with a drip? Makes sense.

Blunt69,

Great advice....I was noticing some slight yellowing on the bottom leaves. Thought it could be Mg deficiency so I really hit it hard w/ CalMag Plus, so that's the main reason for the high EC.

But the slight yellowing could be the start of some contamination from the tubing I'm using.

Think I'm gonna change out the tubing and my res just to be on the safe side. I'm gonna aim for about 1.6 EC, 800 ppm (.5 conversion) as well.

I'll also put the drip back on the timer.

Thx,
Wizberry

Hey Neo,

I don't know much about the Undercurrent myself, but I've talked to growers who build & use Undercurrent type systems. They typically use large netpots (8 to 10") that sit flush with the lid, with most of their volume in water. This is in contrast to net pots which have most of their volume above the water(like what Blunt & me are using).

My old favorite netpot was a heavy duty 5.5" netpot, never used a drip w/ that. Wonder how that would perform in a system like this? I do like the drip tho...it's an efficient way of oxygenating the nutrient and recirculating it at the same time.

Thats for sure is true. I run drippers on a RDWC. I recently caught root rot so I killed some of them ( so no pics) but this is a pic of a single DWC i am running with the water-farms top halo drip (Modded of course)

Neo 420,

The whiteness of those roots looks amazing! Sorry to hear of the rootrot. I've been experimenting w/ diluted compost tea and ZHO to prevent such issues, w/ great success. Plants that have dead roots have actually come back w/ vigorous new growth.

I'm pretty familiar w/ the Waterfarms halo unit. I'm running one standalone Waterfarm unit w/ a humongous Thai basil in it right now. How did you modify the halo ring?

Thx for the terrific pics!

I shortened the shaft to stop all the splashing and drilled bigger/more holes in the top bucket to allow the roots to hang.

Neo 420,

I would love to run a modded Waterfarm drip ring in this system. Maybe I'll experiment w/ a couple plants next run!

What a weekend. Spent all day Saturday pulling NGW tubing and redoing the drip system, just to be on the safe side. It was installed as my main dripline and also on the chiller lines.



I tried to install hard polytubing as the main dripline but it leaked too much. So I had to reinstall the dripline again with Hydrofarm brand tubing.



These leaves are showing stress. I think the combination of high ECs and possible offgassing from the NGW tubing...hard to say.

Luckily there are only a handful of leaves that are really bad. Everything else looks vibrant and healthy.





I followed Blunt69's suggestions. Drained and refilled the entire system. It's running at 1.6 EC, about 800 ppm (.5 scale)/1120 ppm (.7 scale). Added CalMag Plus (to .4 EC) then Lucas Formula (to about 1.4). Cannazyme, Rhizotonic, and a little Root Excelerator to bring it to 1.6 EC. pH is rock solid at 5.7



I also foliar sprayed tonight with GreenStay(1 tsp/qt) and Saturator (1 tsp/qt). Used up nearly the whole quart. I also put the dripper system back on the timer, back to 15 min on every 3 hrs. Hopefully they'll be ready for flowering by Saturday.

Nice!! Get ready for a explosion!!

 

[gus738]

its looking very nice man suscribed, hey how you like your ph meter

 

[Blunt_69]

Hey wiz, can i get a better look ...upskirt shot of the system.

that would be stellar!

thanks dude.

Hope ur rite! The world would be a happier place if we just dropped marijuana bombs on each other.
