Someguys Perpetual Parabolic SCROG Cabinet grow (trying to actually keep a journal)

[SomeGuy]

I think c02 would really speed up your grow.
Hope you get it rigged soon.

I am working on a custom built cabinet design that is modular (breaks into several movable pieces). I intent to have one modular piece hold all the plumbing and gadgets. Hopefully I can get it worked out in the small space I will have.

Thanks for the encouragement Earl. Glad to see you peeking in.

Hey, Someguy.

Love the modular idea. That's where I'm headed with my current build.
I've been thinking Co2 as well...
Been thinkin' I could put dampers on solenoids that close while the gas is introduced.
I don't think I'll turn off the blower after closing the intake damper, only the fans. I think the negatively pressurized cabinet may just suspend the gas around the foliage longer. I'm guessing.

I wanna' see your plans, buddy!

For CO2 to be really effective you need to not be exhausting the room. It would be easier to just put a pressure damper on so that when the room is not exhausting the intake closes... and when the exhaust kicks on the pressure pulls it open. The idea is to confine the co2. The only real way to do this is to air-cool the light and set up the room scrubber on an enviro controller. I wish I knew what i know now when i started building these cabinets. Live and learn...

I will take some shots tonight during feed. The hps cabinet is really rockin along. Probably just another week and it will get thrown on 12/12. The flouro cab is getting closer. Start of Week 7 flower fro the them. I should have clones ready to start in there behind them soon too. Thanks for stoppin in mang.

so am I to understand that your floro grow space and your hps grow space are housed in the same cabinet? or do you have two sperate cabs with exact same dimensions? I am curious if you or anyone interested in this type of growing would know how to figure out the maximum distance from your bulb your useful light sphere would be...well, useful with any size bulb. for example, you say your 400w bulb is 20 inches away from the center of the screen. it appears as tho your parabolic screen is roughly symmetrical meaning if you were to continue your screen around the bulb you would have a 40 inch circle with a bulb in the center. which would have the bulbs sphere aprrox 3.5 feet in diameter, which would mean someone wanting to build a cab would have to allow interior room for that sphere. now if you moved the screen closer to the bulb you would decrease the surface area of the screen unless you allowed the screen to wrap further around the aforementioned circle. So my thought is, if you claim you could triple the screen size, would you keep your parobolic curvature and wrap further around the bulb or would you increase the distance between bulb and screen? I would imagine you would hit a point where the plant would grow up even tho your light source is down in terms of gravity? I guess the possibilty exists that one could increase the depth of your cab 3 fold and place two more sets of screen, slanted at 22.5 degree angles to creat the bottom quadrant of a sphere, none of wchic would every rise above "level" with the bulb. whatever the case, I am cuirious what you think about the most efficent way to construct a cab with 3 times the screen space you have now and still keep the whole screen budding evenly.

Thanks for the awesome vat of knowledge, if I knew how to give you rep points, I Would.

i've been lookin for ages for some info on scrogging and your journal seems the one. nice work man. oh... while i'm here when do you actually put the screen on. im in my last week of vegging too late or what?

Your welcome! I am working on the whole lamp vs distance from screen. obviously my setup is limited by my space to the sides are closer to the lamp than 20" if they get that high. If I air-cooled my light I could get the light closer to the screen and it would be more the way your thinking with screen equa-distant from the lamp. The plant does grow up, no matter what.
So really if I had a wider and deeper screen and I could get more out of my lamp. I am by no means using all the available light space the 400 can cover. If I had scroged when I was in my rather large closet I think my yields would have been more than 1oz per plant.

With these things in mind... I have been thinking about a cabinet 24" deep by 36" wide (interior dimensions). I Think I could keep the height down to 4.5' . However.. That is just the space needed for the grow, not all the plumbing (fans etc). I want to build a cabinet that has a space for raising clones and small plants and houses all the goods for the main cabinet.

Thanks! There are lots of peeps with scrog journals on here. I have only been growing this way for about 1 to 1.5 yrs now, but I love it.

As for your question... I have put it on very late in veg before. Realize that you can do so but may break some branches. If you tie it in to the screen and need to bend some branches rub them a little between your fingers first and bend (dont snap) them over. You will want to let them recover for a week in the screen before flowering.

I think I fucked up....LOL I looked back at my posts a ways and realized that the flouro cab is fiinishing its 7th week going into the 8th... So I was a week off.. OOPS! Its ok though, still growing so I will probably push it a bit longer. Why is it I never write shit down?? LOL

 

[SomeGuy]

Update!

hps cab is 2 wks into veg cycle. I think I am flipping this weekend.

Flouro is on week 8 this week and going quick towards done.

Clones are cloning

Stuff gets here soon for the auto-feed setup. So more engineering soon.

 

[Shackleford.R]

whats the idea for the auto feed? as far as basic design, air pump and displacing the water, or using a water pump?

Water pumps on 7 day timers with drip system.

Fuck I love that t5 grow! Looking good bro! What with all the droopiness with the parabolic-ladies?

They are still coming around from getting their roots to the rez. I have to feed huge in the N department for the first couple weeks of transplant. They are just starting to get a little darker green. They must be dark green before switching to 12/12.


T-5 is always frosty. Just not as big of a producer. I am really interested in Cruizers results from the CMH bulb he is running. I think the blue spectrum makes more crystal.

 

[Knickers]

At my last job I had access to hundreds of t5s, and as the senior manager no one would have known *cries* I just couldnt find enough quick info on them compared to CFLs. Damnit. Would have been a lot easier and cheaper!

 

[SomeGuy]

Update! Engineering:

~Installed drip system to 12 gl rez. Specs
-190glph submersible water pump (harbor freight, got 2 of em)
-irrigation drip kit (harbor freight)
-1/2" ID hose and hose clamp
-hose to quad 1/4" barb
-elbow
*I had the res with two 20gl air pumps on stones in the bottom of a rough neck Rubbermaid.
...Still need a seven day 120v timer to complete the system. I have another pump for the other cab. just need a rez and figure I can use the same timer for both. Will water an hour before lights on for safety.

Here are the pics:

Nice upgrade.

Hempie 2.0 has arrived.

Thanks! I still have a bit to work our with it. I am sure the work I put in now will pay off with less work in the future. Thats what keeps me going anyway..LOL

 

[Shackleford.R]

beautiful irrigation! gonna have to mimic that for my soil grow i'm starting next week. might need something to water for a few days while i'm away on holiday in december. very cool and very well done. whats the GPH on the dripper heads in that kit you got at harbor freight? (i've never even thought to go there for my DIY grow stuff) multiple heads? all same rate?

Thanks! The drippers I am not sure of. I think they are unnecessary as the pump makes more psi than they can handle. But the dripper heads attach to the stakes really well so there ya have it... LOL. I tried dropping the GPH on the pump but even on the lowest it is too much pressure for the drippers to work at their rated drip rate... so in my setup it doesn't matter.

My whole reason was just to do less work. With this setup I should only have to refill my rez once every other week, of course I will still have to make and feed the muddy teas I make by hand (about once a week or so). Not to mention leaving for a few days becomes a lot more of a possibility.

Love your work dude... definatly some inspiration for my upcoming grow here.

Thanks for the ideas and keep it up!
