Sweetarded - "hey, new to scrog, i've pretty much only seen people using plastic fencing, but i couldn't think of any reason galvanized chickenwire wouldn't be fine (and it was way less expensive).
does anyone know if it has any negative effects? does it get too hot or do metal flakes come off of it or some random thing? thanks!"

Depending on the galvanization process and where the product you are using was produced, different metals may have been added to the zinc coating. Lead and cadmium are two that jump out as potentially dangerous. In that many products are used in foliar applications and water qualities differ from garden to garden, the risk of corrosion is quite real. That which can be leached from this cheap metal can be extremely harmful if heated or burned... There I see a problem. Worth the risk? That is up to you...Coating the screen with another material such as rubberized plastic (spray/dip available at most hardware stores) not only helps with corrosion, but can also change the look and function of the screen by changing its color and adding rigidity.

Is it the general consensus that using plastic netting or rope over the chicken wire is best? I see a lot of chicken wire scrogs.

I have already decided that I am going to have an area where I try this when I move and build my new room, I just don't know what kind of screen I will use.

Anyone posted any links to a screen I can buy? Or anyone from michigan want to make a little money building me a cool one? I am lazy and I don't have many tools. I was thinking about buying a table at a garage sale or salvation army and flipping that over and attaching the screen to the legs.

Has anyone used any materials that they really liked or disliked?
 
Cadmium and Lead would be surprising to me if they used them in any sort of frequency in the wire. These are two highly regulated heavy metals, most screens are steel alloys with a Zn coating if they are galvanized. The only real risk from Cd or Pb is if you are foliar feeding, but even then the spray would have to sit long enough on the metal and be acidic enough to oxidize them and for it to be absorbed by the plant. That would take a fairly substantial amount of time(~2-4 hours of contact with the metal) and with a properly ventilated grow room and properly pH'd solution it shouldn't be an issue. If you are worried about it then I would go with the coated screen.

Personally I am not using coated screen because 1-I haven't used up the plain metallic screen I purchased 2-I come in contact with enough heavy metals in my job that a little wire isn't going to hurt me(Heavy Metals Inorganic Chemist). For piece of mind spend the extra few bucks for the coated wire so you don't have to worry about it, can't be but a few bucks difference, but in my personal opinion the likelihood of metal contamination of the finished product is low.

Just my $.02.

Edit-I was incorrect about the metallic content of most screens. apparently most are galvanized steel. I still stand by my assessment of the relative danger levels of heavy metals getting into the finished product.

I don't have ANY tools either. What I did was..

Went to Lowes, bought 2 1x2x8' pieces of lumber. Had the guy at lowes cut it to spec so it would fit in the tent. Borrowed a hammer bought some nails, got a 3 dollar roll of chicken wire from lowes and put it together. Took me like 10 minutes total. Oh, and I bought a couple packs of zip ties to make everything nice and snug.

Nice.

You think that the lowes guys would cut a circular hole into a flat piece of wood, ya know, if I bought it there and paid for everything. I want to put it over the window and mount my exhaust fan properly, right now its just kinda hanging there and the window is blacked out with cardboard and duct tape lol.

Im going to go look on craigslist for a drill, thats something I do need. My tool collection is little more than screwdrivers and allen wrenches. I need to step it up a little.

I believe they can only make straight cuts.

  • "Cadmium and Lead would be surprising to me if they used them in any sort of frequency in the wire. These are two highly regulated heavy metals, most screens are steel alloys with a Zn coating if they are galvanized."

Remember that these screens are rarely produced in our country under the "high regulations" and when you are manufacturing cheep, you use what you have and or what is. Even under our own countries "regs" on heavy metals, do you really trust them to be accurately regulating what goes into these coatings?

  • "The only real risk from Cd or Pb is if you are foliar feeding, but even then the spray would have to sit long enough on the metal and be acidic enough to oxidize them and for it to be absorbed by the plant."

Most here are new to cultivation here, and are less likely to PH or consider what can effect the oxidization. Pest sprays, foliar feedings, use of well water, lack of PH testing, other metals used to secure to the screen (wires etc),unknown etc. etc... The likely hood of oxidization in my opinion, is more real than it staying unscathed.


  • "That would take a fairly substantial amount of time(~2-4 hours of contact with the metal) and with a properly ventilated grow room and properly pH'd solution it shouldn't be an issue. If you are worried about it then I would go with the coated screen."
In your experience here at RIU, are more gardens "proper", not?...see where I am going? Also consider repeated use of the same screen and how that effects the time needed to create a problem. More so however, consider who is vulnerable and who is using these screens...The already ill.

Recall early use of lead/mercury and the beliefs of how it effected our health in earlier years, it is likely that we are unaware of how these can be effecting us and how we could be exposed to that which can be harmful and when at what levels.... I tend to swing toward doing what I can to protect every interest I have including health. Especially considering when speaking about the creation of medication, and that which may become heated or burned.... i too prefer coating, but dont always do what I know is best :D

I hope you're gathering information first and deciding if the application is unsafe based on what you find rather than the other way around. But you were being brief and I probably misread you.
I recently toured "The Breakers" in Newport, R.I., built for Cornelius Vanderbilt in 1893 and famous as perhaps the most exotic residence ever built -- and I noted that the food preparation surfaces were sheet zinc. So zinc food preparation surfaces have been around for a very long time and not for reasons of economy. But that doesn't make them safe, of course.
What would concern me most is that cadmium and zinc are mined together, look similar, and are often plated in the same shops. Sometimes zinc anodes and cadmium anodes are even accidentally interchanged. And cadmium is amply proven to be a powerful cumulative poison with effects on the body similar to lead or mercury. So even if zinc surfaces were found to be safe I would still worry about possible contamination by cadmium.

Double sided tape and emergency blankets are the shiznat they even stick nice to latex paint thats what im running in my box not even using tape. Just tought i would share hahahahah even used cardboard as a backing before to attach the blanket to:-)
 
just an update on my attic grow they are 5th week in veg from seed using coco a+b in 50/50 coco perlite in aquapots they just poking through and i have now lined they room with reflective silver thermal sheeting on either side havnt done back or front as i have fans in the way so heres a few pics(comments ideas will be valuable)View attachment 1749067View attachment 1749066View attachment 1749065View attachment 1749068View attachment 1749063

That is a beautiful set up you have there. Nice attic.
 
I have a 4'x4' box , 8' tall if I use a five gallon bucket for my pots how high above should the screen be? And how high is the light from that? I'll have two plant under two 400 watt MH, strain is Bubblegum kush
 
This is my first scrog grow, what do you all think so far? this is a top view pic i took 30 mins ago

Has anyone scrogged with "ice" by Nirvana ? Waiting for my order, I heard its a good yielder but havent heard of it being scrogged. Also, my grow space is 3'w-2'd-6'h....i have 400w hps & a 250w mh/hps. I think the 400 should be enough for that with one nice plant.......but now that reading about
scrogging has me excited about growing again I wanna exspand the depth to about 4' makong it a 3'x4'x6'.should I add the 250w or get another 400. After growin a few times now im ready to step it
up a bit & seal things up & ventilate correctly.......thanx for ur thoughts & replies people.
 
I have a nirvana ice seed but I am still growing Strawberry Diesel so it'll be a few months before I can get going on the Ice.
 
Hello scrogers:) Im about 1 week away from florweing. Im pressed by time, as ill have 4 plants ready to go into my perpetual with 2 mnths. So ill need the light they are under, thus flowering when the screen will be approx 70% full.

I just pulled under the screen again yesterday, and when it gets back above it ill be ready to roll^^
