A Tribute to JonJaffer - 4K Vertical PVC Stadium

[redspaghetti]

i re-read your post

you're saying temp stay cool when lights on

but cooler when lights off?

I do see a lot of cripsy leafs but not just the bottom row

I had plants as close as 8 - 10 inches to the light and they're still green


I cant see clear pics but i think its either

A- Ph
B - Temp


post up clear pics ye cheeb?

cheers bro

i have the same issue with the ventilation not sure excatly how to set it up in minus -20 weather. my room dipps into the low 60's when im filtering the air and at nights when i shut the lights off im sure its gogin to hit low 50's so untill i figure it out im leaving my plants in veg .

Hey guys,

thanks for the replies.

I definitely blame it on out of wack pH as I know pH rode around 4.0 for atleast a few days to a week before being corrected - our stupid mistake.

I'm not 100% positive on temp up in the canopy as I dont have a good thermometer, but its definitely NOT hot in the room (ambient). I'd say ON temp is around low 70s to mid 70s, but light OFF temp as to be getting very cold as its pulling in 20F air (its winter now).

Does anyone know how negative of an effect cold nighttime temps will have while maintaining near perfect daytime temps?

i have the same problem. i picked up a cheap heater a home depot for 45 bucks its the lasko ceramic tower. it has an led readout so you can dial the temp in. you could also get another fan and filter, smaller than what you have, and have it just recycle air in the room. at night.

I dont really want to waste a ton of energy creating heat as it'll just get sucked out of the room so I believe your suggestion is the best bet. I'd hate to haul in another filter but cutting exhaust around 1hr before lights off and just kicking on another fan/filter to combat smell during light off seems to be the easiest solution.

1st though..
I'm going to try to block passive intake during light off so maybe it'll just draw house air keep things warm enough - pulling house air down the steps or something.

All in all I'm pleased with how things went - bit of a leak which I believe can be fixed by hacking the bolt which protrudes down into the tube giving roots a spot to tangle up at...other problems were 100% human error.

take care all

Wow Cheeb....

I was first goin to say I thought the pipes were set too far apart...but as I followed along I see you vegged for how long? 1month? Didn't see sorry... so you got huge growth!

I would've done the setup with 3 rows each side, and pipes closer together, but almost no veg time either..

VERY NICE my man! I am INDEED impressed... I don't know who JonJaffer is, but I'm sure he'd be very proud!

 

[Mybud]

Well, despite the pH troubles I think they're lookin pretty darn good Cheeb Did you do any trimming/defoliation of the lower parts of the plants?
Props to you Man and Happy Holidays

I agree, looks fantastic! I love R & D

The cold temps drastically decrease growth. I know from experience growing in an attic. 20F you've got to be f'ing shitting me. Get a smaller exhaust maybe? run the big one while the lights are on and the small one at night. That way you can run a space heater without exhausting all the heat... You gotta keep them warm at night. Like 60F. 40F is the minimum. 34F is freezing and now you have cell damage... Temperature effects metabolism. imo pH fried your leaves... not such a big deal, you were done with them anyway... ha ha... just finish it out.

First off nice job man! I've been following this thread for a while now and I am liking what I see. There are always some setbacks when running a system for the first time and especially with friends. Keep at it and remember 3rd times the charm.

As far as your problems I would definitely blame the burning on the PH. If the leaves are crunchy but still have some color it's usually PH. If they are crunchy and brown it's the EC. I don't recall how your top up system works, I should have this thread memorized by now, but you might want to incorporate a separate tank to store top up water. This would allow you to PH adjust it to your max setting 6.0-6.2 and have it auto top you system. This way even if your system dropped to 0.0 EC the PH would still be in the correct range. Also less stressful for the plants than having PH down dumped in while recirculating. Could be as simple as some hose, garbage can or plastic drum, and float valve.

For ventilation you could build a thermostatic controlled outlet. Plug the fan into the outlet and set the temp and when the room hits that temp or above the fan is on. When the temp drops the fan shuts off. Pretty simple to wire need an outlet, thermostat, DPDT relay, some wire. Google for directions.

I have see fox tailing like that as a response to a stress, cold temps, ph, light cycle change, ect..
Just cut it off at harvest time and make some hash

Keep us updated and remember when growing with friends you can't make things idiot proof, just idiot resistant.

 

[mdk ktm]

yeah I had low PH issues once, the dude used tap water instead of RO and the leaves looked exactly like yours. Brown and crispy. It really effected my yield and they probably wont recover, You might want to just chop all those burnt leaves off and see what happens. Because whats the point of a brown, crispy leaf?

Good luck cheeb I hope you still have a great harvest.

 

[Canada]

Hey!!!! Whats Growing On?

 

[SatoriSOG]

hey, how are the ladies doin?

 

[Cheeb]

been really busy. thanks for all of the replies and sorry for not getting back to any questions. I think we vegged for around 1 month.

I do believe cold temps where the main culprit in this grow going a bit wrong. One variety turned out fine..dense frosty buds... the other however must have been a lot more sensitive as it was ruined. We had to have been pulling in very very cold air for some time. Tried blocking our big passive intake, but it still was pretty damn cold.

The EW (right) side came down looking great. Super frosted, and had lots of deep purple.
It still has a hair of moisture in it, and I originally thought it was going to be about 4 lbs from just this one side, but it'll most likely be more around 3-3.25 lbs.

The LemG side is absolutely awful. Its frosted and reeks, but flower development went totally haywire. Had to be related to environment (cold) as the other side turned out good. We didnt get around to pruning this side so there is a TON of larfy bullshit, but unfortunately even what look like giant colas from a distance are just a bunch of loose/unconnected calyxes upon closer inspection. I wouldnt call it a foxtail, but more like clusters of frosted round parts..almost like how grapes look.

Its almost like the plant went back into a vegetative state. I've got little calyxes on tiny stems growing off of other buds. Really weired looking and absolutely devastating. Still in the process of trying to plow through this stuff using a Trim Reaper (thank god), but it really all deserves to be in the hash/butter pile. We'll see what it looks like when its bone dry and hope for something. My buddy living here is dead broke so we gotta try to do something with it.

try try again I guess. All in all I'll chalk this one up. It is promising because if both sides would have done as well as the right side here we'd be looking at around 6-6.5 lbs from 4k in 10ft of length. I dont see why we couldn't hit 4lbs per side with a little bit of practice and better environmental control. Come summer I think it'll have to be mini-spit and sealed...or I might just try to drop 1k so that i'll be a 3 lighter.

next round will be flipped earlier, and stripped hard.

 

[cocktail frank]

this is a real pro grow here man!
i appreciate your attn to detail.
and it shows!

 

[cameron666]

that looks amazing, did you ever think if the plants get too heavy they might flop over and twist the tubing they sit in? welldone on the design and outcome

 

[Cheeb]

Dont think that could ever happen cameron666. Maybe without the eye hooks and chains being attached to top dead center, but not in this scenario.

No further pics but this yeild was a hair over 5lbs from the entire stadium.

2.75 lbs from the good side.
2.25 lbs from the bad side (a notorious heavy yielder).

The bad side was complete crap in terms of solid bud development due to extreme temps I had going here.. but its still super frosty and dank. Had to let it go very cheap, but atleast it can still be considered a success.

JonJaffer used to get 6lbs off of 3000w. We hit 5lbs off of 4000w. No doubt we can get these numbers up with some dialing and environmental control.

Stay tuned for a future run. Cuts are rooting now. Didnt due the whole perpetual thing this 1st run. Will make a dedicated veg stadium after we reload this flower room.

 

[Bud-Boy]

wow. now thats inovative
il be watching.

Have 2 no-medium projects I've ben slowly gathering for over the last few years.
one is a 3" tube octagon. Bending pvc on a template with a heat gun. Constant flow through the tubes, dammed on the capping end, and over spilling down into the next level (internally). semi stadium style.
Essentially a RDWC w/o bucket

and then
a RDWC bucket system Im going vert w soon

Best wishes on this one friend

 

[Yes4Prop215]

nice looking grows man..definately post some dried pics. but yeah im having a similar problem with cold temps at night....my friend solves this by running an exhaust from a flipflop grow room, so warm light-on air is always heating the lights-off room.

but i dont have this option, and neither do you, so we gotta figure out something similar.

i thought about the cheap home depot heater, but those things run upwards of 1000 watts and you are right, wasting money to create heat that gets sucked out.

so i might have to try the fan controller thing and slow down my exhaust or even turn it off at night.....i think thats better than setting up a second exhaust system...i hate punching holes in my drywall lol..

"Its almost like the plant went back into a vegetative state. I've got little calyxes on tiny stems growing off of other buds. Really weired looking and absolutely devastating."

Yup, this can happen to outdoor plants when the nights get real moist (and cold I believe) That is not my forte although I have heard it mentioned and seen what your talking about - heard it called 'molting.'

Kinda looks like something I might want to call hermie although I feel it is triggered by such influences signalling for the plant to begin a partially re-vegetative lifestyle.

Yeah perhaps it could be easy enough to run something inline with the intake the heats and dries the air coming in, off course it would have to be setup to never run with the lights on. Probably just turning it off would be better and just fine.

Thanks for the thread Cheeb! I have really enjoyed learning from this

 

[5th]

Yeah Jon gets 2g/w. You ain't him bro. Neither I. Your grow had a lot of factors(bad ones)
This isn't the other forums...you didn't fuck up. Anyone who says different's a fucking idiot.
Once you get this dialed your going to be killing it man. Fuck staying tuned, SUBBED until you stop posting.

 

[rasputin]

Very nice, Cheeb. Looking forward to round 2, keep us posted.

 

[laylow]

Nice grow them nets looked like they was ready to burst!!!
