Today I built a screens for each of my two flower closets, I made a little step by step incase anyone following along wants to learn to make their own. For more info from the grow pictured below you can follow my grow journal:




Step 1: get the supplies! Wood, nails, corner brackets, string

Step 2: attach corners, take note the the total length of your screen is going to be the length of the wood you used plus the width of the wood you used. If you dont quite understand what i mean by that then analyze this picture

Step 3: Mark off every 3 inches along the inside diameter of your frame. Be sure that all the dots on both sides line up so that you get squares rather then diamonds

Step 4: put one small nail into each marking

Step 5: Wrap one continuous string toughly around the nails forming squares

Step 6: Mount in grow room (picture of Flower Closet #1)

Here is some additional advice Iv written on what to do after you have the screen built:

The screen is basically a tool that you use to keep the buds in the canopy spaced evenly at the same hight. The whole point is to not have any buds shading any other so that they are all top nugs!


Keep that goal in mind while training the plants. As the first nodes go up through the screen you will need to pull the node back down under the screen and then back up one square over. This will keep the tops at level with the screen.


Your main branches will hit the screen first, train these branches to the outside edges of the screen! These main branches are the fastest growing (hence why they reach the screen first) and if you try to put them in the center of the screen they will shade the other nodes.


The light is strongest directly under the hood in the middle of the screen so these nodes will grow fastest while the edges grow slower. Left to their own devices this will cause plants canopy to grow into a dome shape, this is the opposite of what you want! Tall branches in the middle will shade outside branches while also forcing you to rase your light. The perfect SCROG canopy is concave with the tallest branches all around the sides, but this is hard to achieve and i am usually happy to just keep the whole thing flat.


Heres a little visual representation of how a screen should look as it fills out:

Thank you so much for such an informative tutorial. I just fimmed my ladies and wasn't really sure if I did it too soon fimming at 6" at the 5th and 6th internode.

Beautiful canopy, how long did it take from seed/rooted clone to transition? And what strain?...looks tasty.

Glad I could help, that sounds like a good hight for that. You should start doing some low stress training about that hight to get them ready for the screen!

Thanks! The canopy in the first post is different then the one in the second post. The first one is part of my current perpetual, that closet has 6 plants that were about 4 weeks into flowering when that pic was taken, 3 kush and 3 of unknown genetics under a 600 watt.

The pictures in the second post are of my first grow. That was two Headband 707's grown from clone under a 400 watt light. They spent 5 weeks in veg and 8 weeks in flower.

Thanks for the thread man! I just did a SCROG with a tomato wire thing and a wire screen sware that a friend gave me to elivate the plants in their saucers so the roots don't sit in that nasty water. Sounds trailer but if you don't have the room for what Naturalist did here do a solo. Just be prepaired to fall in love with SCROG! It only added about 2-3 weeks veg time but as you can see the results are good! Not as good as The naturalist but I am happy! ;) this way also allows you to move the plants and it was VERY easy!

What kind of LST? What should I try to achieve bending the ladies?

Thank you for your help

If you intend to ScrOG your plants then you should use low stress training to make your plants get branchy. By bending your plant over you can expose light to the nodes (at the base of each leaf), exposing them to light makes them grow branches.

Good thread Naturalist. When it gets down to page 2 I'll put it in the DIY section so it's handy (and appropriate).

With all the traffic the General forum gets it will be on the second page in no time. There are not a lot of new articles in the DIY section so it will stay available there for a lot longer.

The reason I like this is this: It's short, sweet, to the point, and your not overwhelmed with too much information at once. and it looks cost effective. a few bucks at most?
