Trellis netting installation if/or Q

rmax · Mar 13, 2023

I want to use a trellis and am double checking on how to properly install/use.

The plants are growing in a 5x5 side of a 5x10 Vivosun tent and the trellis netting size is (3.5" square mesh, 5' x 15'). How should I support the trellis so that it can support the weight? After installing the trellis I'll cut the excess away.

Is the idea to weave branches so they are held down and later held up from all the pineapple sized fruits?

TIA>

You can use trellis netting to stop your buds from flopping over or scrog (weave branches so they are held down). For holding the buds up, connecting the net in the corners is fine. For a scrog you're going to want to support it on all sides so it can resist the upwards growth. PVC tubing or some wood should be sufficient.

Personally I never liked trellis netting for SCROG because it's elastic and works against you. I used regular chalk line replacement string on my scrogs.

How are your scrog sections secured? I assume they are somehow, as the plants would lift them if not. I just can't see where or how they are secured. I grow in a 4x4 tent and just secure the netting to tent poles in corners. Curious what secures yours.

They're secured to the walls with screws. That's a wood structure, the panda film made it look like a tent. If I was doing it in a tent, I'd build a PVC frame and secure it to the corners. Gorilla tents have a high CFM kit that I used when I was in a 3x3 tent.

I've given up on scrogging and try to keep everything simple now.

The thin green nylon stuff? Not recommended for the main netting for a SCROG. Hardening branches will shred that stuff.

But you have a really nice set-up ... just wondering what you find complicated and/or more difficult about SCROG's?

Nugnewbie · Mar 13, 2023

Am considering that myself. Scrogging makes it more difficult to work on plants and medium. I am growing in SIPS, so topdressing is a pita under the netting. Want to maximize yield, but not sure I wouldn't just get about the same amount of bud at harvest anyway without it. I am supercropping in an effort to keep the canopy somewhat level.

Thanks, I just found it labour intensive. Hours spent tucking and trimming every week were hard on the back, and the long veg time was a bit annoying. I don't find that the yield was better than topping and maybe a little LST.

That chalk line will shed microfibers on your flowers when you cut the strings at harvest. Regular plastic trellis (not string) netting does not stretch much once it is pulled taut. Use 2 layers to keep buds from flopping over at harvest.

You are welcome. And I can't dispute any of your rationale. It's the knees in my case since I kneel on a concrete floor to do plant stuff. The plants themselves are not on the concrete - it's just these old joints down there.

I have a third plant going and should it end up being a female, I will also be forced to abandon the SCROG. Physically, I can't secure a third net in my VEG area so I too would employ some topping and lateral LST to make ~24" x 16" canopies.

You have a clean looking setup.

The netting is poly so will slide down the poles and the center will sag from all the weight of the pineapples. After seeing your setup I don't see the point of this poly. It's a toy.. I must prefab something and may just have to use sticks on my current grow. And have a custom tent next grow.

Get some wire fencing and suspend it from the tubing at the top. Then it can easily be raised when you realize it was too low to start with and needs to be higher saving you having to install a 2nd net like I see so many doing.

Easy-peasy DWC ScroG setup. Hanging from baling wire so as the plant grows taller the net can rise with it.

Support from the ceiling up front and the back on hooks in the wall tho could also be suspended from the ceiling. Bamboo stakes for a quick frame. I cut the wire so stubs stuck out then used pliers to bend those around the bamboo so there were no pointy ends sticking out and the bamboo was firmly held.

If there's an easier, quicker way to do something that saves me money I'll find it! Took me about 20 min to throw that together but a couple days thinking to come up with the plan.

:peace:

Now that I've seen what other growers are doing the simplest might be 4 cinder blocks in the corners of the tent < tie down a twin bed frame to the blocks for the stability.

Something like this should slide right in to the tent.

A disadvantage in the tent is string/rope being fished through and around the light fixture. You have a custom ceiling and can create custom hook locations.

Good point about misinterpreting the height.

I use ac infinty trellis to hold up the branches … use two of them .

lusidghost · Mar 13, 2023

I used pvp to build a frame with screws to stretch the net over. I hang them off of my tent frames. That way I can adjust the height.

The only time that the plants lift the net is when they are too tall going in. The net trains them more than holds them down, really.

Don't set net until buds develop. Use between 3-5" squares. You'll understand when harvesting.

Most frugal or cheap route is 4"x4" mesh roll of garden fence. Cut to tent size and nylon zip tie to tent frame.
I tie my own. LOL.

Stretch in flower and and pain in the ass removing when done.

And from you?

Why the laughing emoji? That was an honest question. I've never not scrogged, and any time I try to add them that late into the game it becomes a nightmare of breaking stems and shifting the canopy around.
