Back at the scrog!

Hey everyone, I got a new grow space and have started a new scrog. I'm working with 3 plants in a 54"X34" with Violator Kush on the sides and a Chocolope in the middle.

I have my co2 set up but the new tent has no exhaust vents left, my question to you all is this: Is there a good way to have an intake and output that can be sealed until the exhaust fan kicks on so I'm not just dumping co2 out of the tent all day?

Here's the breakdown so far-

2x600w mh for veg

promix in 5 gal buckets

2 tbsp per gallon "Plant Energy" local hydro store mix, going to run fox farm big bloom and tiger bloom for 12/12

1500 ppm co2 20 gal tank

The co2 controller is a CAP ppm4, super basic- It can be put on its own timer or just hooked up to the light timer, it will turn the tank on until the room hits 1500 ppm then it will keep it there.

The humidity is around 60% right now, will get it a tad lower as flowering begins, the room will struggle to get below 40% so I will have to have a lot of moving air.

Very nice I'll be keeping an eye on this thread. How long do you plan on vegging?

This deserves some + REPUTATION! ...and subbed

Gonna veg another couple weeks, trying to fill the canopy out before I flip to 12/12.

Thanks for the good words

I had to put them in to flower 2 days ago, the Violator Kush was getting super tall and I didn't want them to take over the room before they even went through the stretch.


I think I got the ventilation situation squared away, I installed a couple 4 inch couplings at the top of the tent, one with a hose coming down to the floor for fresh air and the other pulling air from the top of the tent on a timer set to go off for 15 min every hour. The fan I'm using to pull the air out so pretty sad but my 190 cfm fan wont be here until Monday so it will have to do, temps are around 78 at the base of the canopy and 85 at the top of the canopy and co2 is staying around 1200 for now.

how long does the 20lb tank last you?

We are gonna find out, I have only been using it sporadically until today, I didn't want to close up the tent all day so I could crank the co2 and let the heat and humidity spike. Based on the calculator I will probably use a tank every 2-3 weeks, I will keep tabs on that and report when its empty

Looks good. I hope you have holes in the bottom of the 5g Lowes buckets.

Yes sir, yes I do

Well, I had a power outage the other day and forgot to reset my timers... for 2 days my timers were out of sink and I was venting the tent WHILE releasing co2... so to answer the above question of "how long does a tank last?" about 5 days when you totally screw up your timers.

I think I'm going to have to get myself a cap AIR-3 so I don't have to mess around with dueling timers. Temps are still running a bit high, around the low 80s up to 85 when the vent is off and co2 is full blast, I'm attributing most of the heat to the weather, the setup is in a basement but with daytime outdoor temps climbing above 90f its tough to keep the basement cool and vented. There may be a AC unit in my grow room's future but I'm trying to hold off if I can, winter temps here are well below freezing with very low humidity so if I can get past this grow I will be in the clear for my next 3-4 cycles.

My last setup was in an apartment bedroom, venting and cooling was easy because of the windows but venting a basement without cutting holes in a rented house is a bit more tricky, humidity is also more of an issue here because of my proximity to the water table. Don't get me wrong, I will take a basement setup over an apartment setup any day, its just a different set of issues.

You can get timers with a battery back-up built in, cheap. I think I paid £12 for 3.
The VK has 2 distinct phenos. I grew out the shorter, stockier one. It looks like you have the other.
Good luck.

Thank you sir, I do have the more sativa VK pheno, they stretch like a sob and finish at around 9 weeks. My Chocolope seems to have an odd genetic variation as well, some of the leaves are turned counter clockwise for some strange reason, there also seems to be what I can only call "chlorophyll clumping" in the distorted areas. At first I thought it was a nute deficiency but I took clones and put them in a different room with different nutes/airflow etc and they also grew curved leaves. We shall see how they turn out, I may need to get a hold of another seed if it turns out these genetics have a fundamental flaw.

The power outage was a breaker popping, I'm going to need to call in an electrician, for now I diversified my outlet usage but I'm limited by the electrical of my space.

Here's a pic of the leaves, they don't all grow like this, but enough that it bothers me.

The first pic is the adult/mother the second pic is a clone.

i like your setup.

i love the spacey feel

i have always wanted to set up a tent like this.

it would make taking advantage of cO2 like you have much easier

Thanks much, its honestly a bit more room than I need, the tent is 76x76x76 so over six feet in all directions for just a couple of plants. I feel like I could control the temp/humidity a bit better with a slightly smaller box but this does give me room for a big project if I need it, I may try to get 2 plants to fill the room wall to wall at some point, I'm vegging 2 Chocolopes now for that gig but it may be 6 months before they are big enough to make that happen.

Looking good, I think tents are the way to go....

Out of 5 fem seeds, I think (was a couple of years back) I got 3 short phenos, 2 tall ones. Unfortunately I had to yank the taller ones as I was in a limited height scrog. The shorter one barely stretched at all. About 25% maybe. Seem to remember it went 10 weeks but had temp problems (was a loft grow). Cloned real easy too, 100% showing roots in 7 days. Only bad thing was it stank. Even in veg. Lovely, heavy smoke though So much so that after a couple of 600 grows producing about a lb each, I gave up smoking for a year!
Are your 600s running on seperate ballasts and contactors? If so, you can put them on seperate timers, a couple of minutes apart to stop the breakers tripping. It's the initial surge to strike the arc that trips breakers.
That second pic. Ae you sure those dots on the leaves aren't RSM?

It's not mites, I wish it was honestly, that I can deal with. The deformity is only effecting the center leafs of the 7 like, the middle 1-2 points are effected and the rest of the plant is healthy as hell. I haven't found any other examples of it in any literature and I have grown many strains over the years and have never seen anything like it, this is what leads me to think its a genetic abnormality.

You aren't kidding about VKs stinking', this is my second year growing this strain and honestly it smells worse before putting it into flower, I have never worked with another strain that has such a heavy skunk smell before it even shows flowers!

This Pheno is definitely a stretcher, I had the shorter pheno before but I accidental got the clones mixed up and sent my last short one into flower over last winter

The Choco is kinda being a bitch, some branches are shooting up as fast as the VK and some are right where they were a week ago before I started 12/12. I am doing everything I can to make the canopy uniform, bending tall branches and giving the shorter branches room to stretch. At one point I thought the light wasn't penetrating the middle of the scrog but I checked it with my lumen meter and light coverage is even across the board.

The idea of putting the ballasts on different timers is a good one, I will do that in the interim while I'm trying to get an electrician over here. The breaker tripped in the middle of the day and I'm pretty sure I know why.... Right now I'm running 2x600 watt ballasts, 1x 500 cfm fan, 1x 190 cfm fan, 2x 100w cfls (veg tent), 1 standing fan, 1 co2 monitor, 1 standing fan and a dehumidifier... all on 1 breaker. Now, before you guys say "dude wtf, ur dum" The electrical was a mess when I moved in and I needed to get rolling right away, I was able to get one double outlet working and I had to use it. I think I found an electrician I can trust (as a legal grower I'm more concerned by someone robbing me than calling the police) now I just have to get him over here.

Since I'm pointing out my flaws I might as well tell this little gem of a story: I thought my timers had just gotten out of sink because of the power outage, as I said before- I was venting the room while the co2 was on because if my sinking issues. I took a better look at how I had things plugged in this after noon and realized I had made a major error (this story I hope will deter people from being hasty in their setup... and also doing it stoned) I had put the co2 timer on the power strip that was running my ballasts, forgetting that I had plugged that power strip into the timer for the ballasts, in essence this cause the co2 timer to "flip flop" ever 24 hours, every other night I was filling the tent at night while venting the tent... Yes, this was hilariously stupid and it cost me a bunch to make that mistake, but I sure won't make it twice!

Took some updated pics but they all came out fuzzy. My good digital camera died and the backup sucks, I was able to get one in focus.

This is nine days of 12/12.

i hate it when the battery dies.... hey nice grow..... what are your temps in there looking like the leafs are comin up on the edges...

Temps were running a bit high for the first couple weeks, low to mid 80s but most of that leaf curl is the genetic issue with the Chocolope, the VKs are pretty straight.
