DIY Scrog

What's up growmies.

I purchased a scrog a while back and never ended up using it. One of my biggest concerns was that the squares between the strings were too big for my liking. They were roughly about 25cm to 30cm big and wanted something smaller. So I went and collected a few things around the house and bought a couple things here and there.

So firstly I cut 4x pieces of 1.2m pvc conduit piping (25mm). 4x corners for those pipes too. I built a big square that would fit into my 1.2m tent. Please note all measurements are rough estimates as my tent wasn't exactly 1.2m. The inner sides of the tent poles is what I used as my size which was slightly smaller than 1.2m.

I drilled holes along the conduit piping and drilled them straight through. I decided to tie each string individually about 11cm apart. The reason I went with the individual string instead of one long string that gets weaved is simply because if one of my strings break, the whole rig doesn't come down. If one breaks, just that line will be broken and can then be repaired seperately.

I decided to use string I bought at a hardware shop. The string is used for shade cloth, gardens etc. One packet of 30m cost R30. So was pretty cheap. I had some steel ferrels that I had left over from another project. I cut them in half with a steel saw (super cramps in the hands trying to hold with a pliers and saw. Use vice grip if you have). I only used about 18x ferrels. Made my squares about 11cm apart. I made a little knot the one side and then took it through the other side (making sure there's not too much tension) which I then used the ferrels to keep them taut (by squishing them with a side-cutter. Just not too hard that you cut through). The pvc pipe bends easily so check your previous lines as you go, not to make them too tight.

Once you have finished one side of, let's say the vertical side, when stringing towards the other sides horizontally, make sure to go over and under the vertical strings.

I ended up using some cable ties just to tie down my DIY scrog to the tent poles. I'll be using this scrog to keep 4 plants down. This is from inspiration purely from this forum. Some of the guys that have made their own scrogs have done some nice ones. As I mentioned, there are plenty of different kinds of material, methods and ideas that can be used to do this. This is just one of them.
