Large SCROG Build Step-By-Step

G

Guest

hey guys i'm going to be starting a new grow but i just thought i'd make a quick post about a basic growroom design feature that i think would be a big asset to anyone using 2 lights in a limited amount of space...actually my space is pretty unlimited but i think SCROG is the best way to keep plant numbers low and get a canopy that has maximum light efficiency.

Here we go...gonna post the pics then maybe go back and comment on some...Most speak for themselves...i use mason line, knotting and then melting the nylon to ensure no bullshit...

for materials i got

12 48" 1x3s
7 42" 1x3s
2 90" 1x3s
~160 feet of nylon mason cord. i feel nylon is key.

First up we got the 1x3s from home depot...for the record the wood totally sucked and was not 1x3 it was like .75x2.5 maybe...very much a pain in the ass drilling these things which is why i had to go with the two end pieces arranged as they are instead of attached as an outside wall...

done stringing the frame...the cord was interwoven to provide greater rigidity in supporting the plants...5 gallon (20L) bucket in foreground...

here is a cross-section view of the support slats i built...its 2 48" 1x3s sandwiching a couple of 6" blocks...the second block was situated at 36"...the frame will slide into the slats...

all 6 slats

I added crossbeams to reduce torsion between the frame and slats...i highly recommend this, nothing could be worse that bumping the screen and have it twist and gnarl up a canopy ack...

at first glance it may seem odd to put the blocks so low on the support slats but my intention was to slide the frame down, veg the plants about 4"-6" above the canopy and then have a second line of framing if i need to add additional screening...this would probably be done with netting but i may consider building another frame if the plants get real big but i am not anticipating very much stretching from my strains...

OK that's it for the setup...there are two sides, each is 45"x42" and each has about 120 holes in the screen...there is a 600W HPS for each side...the grow will be done in soilless containering but i firmly believe this would be an effective structure to grow a fastvegging DWC system underneath...on another aside the flooring is a 12'x12' sheet of panda film which i stapled to the walls and created flood/stain protection for the carpet underneath...i will probably get some cinder blocks to set at the corners of the sheeting and it slides a little but i like it a lot, it makes it look cleaner and is reflective...i also have the lightning 97 reflective material surrounding the scrog...there will be 12 container plants grown under two 1000W lights in front of this SCROG so it will be interesting to see them side by side...

I may come back and do another update about filling the screen in...but this is mostly just to get the hardware aspect for an effective SCROG frame in a visual format for those who might otherwise be put off from building it...it is a little work but use the mason cord with a pair of needle nosed pliers to thread the knots and it will go fast...i'll post a link when it gets filled in but i think the grow diary will probably be on OG...

peace,
phat

you can totally get away with just one 1000w over one of those sides....thats just me though...i would use the othe thousand for more plants...

the 2 600 is awsome over the other..

NICE NICE setup man....really clean...you thought this one threw and it shows!!!!

Aloha...

i'm gonna go with one 600 over each side (those are the 6s in the last pic, they both run off of one 240V ballast how phat is that?...but there is like 5 or 6 feet of depth from the end of the screen to end of the plastic so i'm going to put the 1kw lights in front of the scrog hanging over plants that won't be screened (probably)...

here's a better perspective on the room after i put the plants underneath the SCROG and got the others in front...eventually the plants on the floor will be spread out and put under two 1kW lights...

nice and clean!!!

i love the 2X600 Watters on one ballast!!!

if you don't mind some questions...

>do you vent your grow?

>hows the temps?

>what do you use for odor control?

>do you like the growbags?

hey u guys are the best, wrecked, issack, bigbud, sysprog, mr. mustard, BT and Sleepy :wave:

Sleepy- i love to answer q's...i do not have an active exhaust fan yet but i will in about two weeks...i have an intake which is the A/C unit...this will probably be swapped out for something when it starts to get real cold...i also need to get a hygrometer but i would say the temp with the lights on is about 80 and the humidity about 50%....i like to run the grow room a little hot as i feel the plants grow better at 85 than 70...i got two big fans for circulation so that helps...at the moment i got the vaportek4000 going and used it for my last flowering run but will be adding a carbon scrubber this time as well, when i get the exhaust fan...i do like the growbags, i actually have transplanted the 1-gallon bags into other 1-gallon bags to try to maximize vertical root space to see how that works...it was a tite fit and i hope they don't tip over LOL but i think it will work well... they also are very easy to stack next to one another if u have a common drain table or something...also they fold up and u can carry 30 of them in a little sack upstairs but everyone in the neighborhood is gonna know if i'm carrying 30 or 60 plastic pots around...they are also pretty reusable for a couple times if u wash them out and bleach them...

thanks everyone for the interest, i will be starting a thread on the actual growing in the indoor/soil subsection i think as this was more for hardware...that being said here is a pic of that duallie 600 setup i was talking about for 240V...










this ballast is super light and i can hold onto the thing after its been running for hours and its about 80 degrees...don't do that with ur ballast at home LOL! i got it from www.gchydro.com they are good people to work with...funny thing is when i picked it up at UPS there was a cop helping them :dueling: (don't ask me why but he was there and it was a drag)...they had a hard time finding the second box of the shipment, i basically had to find it myself when the woman couldn't figure out her computer system all the while this cop is trying to organize everyone who was there to pick shit up...so she could only find the ballast and was making a big deal out of how heavy it was in front of the cop and of course he was like, "what's that" and i said "computer equipment, its a UPS for our server setup" since it said external ballast on the side of the box...luckily the woman found the other box and i skeddadled with it all...point of that story is the reason he had no suspicions was cause i was super nice to him, asking him if they had sent any folks down to help with katrina Blah blah blah...i don't particularly like cops but knew the happy face was key and cops are such that they think if people don't like them or are doing something they shouldn't be doing then those people will get nervous around them and act uncomfortable...i knew even if he couldn't bust me for the lights he wouldn't be above snagging my addy and even though i don't grow there i don't need the grief...as it was i waved goodbye, he thought i was a nice guy and that was that...

i'll have that new link when i get everything posted :yummy:

peace,
phat
