Trellis

i cannot afford to buy the botanicare sliding tables yet so i need to setup some temporary trellis for this round. i don’t want to drill metal poles into the ground.

anyone have any ideas how i can secure PVC frame to the floor without drilling. i was thinking maybe those things that hold a umberella on outdoor tables.

nice looking room
umbrella holders should work. i use cinder blocks filled in with concrete with poles stuck in them. i keep fabric underneath to avoid fucking up my epoxy

In the past I used 5 gallon buckets with a stick of EMT and concrete. My big plants started tipping the poles due to the weight but for normal plants it would work. I hated the space they took up and went ahead and made my current trellis rigs.

@Renfro Off topic here, but do you think if i hung 2 inline fans in opposite corners of the room it would circulate enough air to not need wall fans and not beatup any of the canopy? like 10-14 inch inlines.

I suppose that would depend on the size of your room, I would imagine there will be areas with much less air movement and areas with more than required.

To make an inline fan really work efficiently, you could run 12 inch or 14 inch galvanized snap seam, run that to a reducing tee with a smaller take off blowing air, and then keep going for three or four take offs, reducing the trunk line diameter as we go to keep velocity up. Run that along a wall, up high just under the lights and above the canopy. Do that along both walls and you can spread the CFM of the larger fan. Does any of that make sense? lol I smoked a bowl. This works good for larger rooms that need circulation in areas that aren't near a wall (middle of the room), run it along the ceiling between rows of lights and blow down with air diffusers.

Really though, back to your question, I would think a few wall fans in targeted areas will still be required. Having to figure out where to put fans and them not being in your way or blasting plants can be a real bitch. lol It gets a lot harder the shorter your ceilings are and taller your plants are.

I run my carbon filters with them standing up on end (they are 48x12 phat filters) and I run a short length of duct straight up and put the blower and an adjustable elbow off the blower to direct airflow. I set the length of that tube so it will end up blowing the air just under my lights on a row in my room. So the two rows that are along walls have those blowers doing double duty, scrubbing air and cooling the canopy / moving heat from under the lights. Then I use a combination of wall mount oscillating and non oscillating fans and floor fans both pedestal and ones sitting on the floor, even have some smaller ones blowing up to cool vertical bulbs / side lighting. Keep that air moving to prevent micro climates, hotter areas, more humid areas, those are just bad news.

One trick I have done is to use a stick of strut channel, mount that vertically on the wall and then mount the fan to that with spring nuts (bust the spring off so they will slide easier). Run a bolt through the back of the spring nut so it makes a stud (red locktite that), insert that stud assembly into the strut channel and use a fender washer or square washer then mount the fan with a wing nut. Now you can just loosen the wing nuts (while holding the fan lol) and slide it up or down and tighten it back up. I posted pictures in another thread. It could get awkward though with typical fans because youd have to build some sort of adapter.

No. In a room like that absolutely no chance I would try and avoid good airflow.
Never seen a fan beat up a plant. Get them dancing or risk losing the whole room to rot.

Im not trying to avoid good airflow, i am trying to promote it. Growing in coco. I dont think the inline thing will work either. What reno said above sounds great, but i dont know how to make reducing venting like that. Will have to do more research and planning and just hang 10-12 oscillators for now. I have like 3 weeks before this room is going to be used.

If your growing in coco then just ram some stakes down the sides of the pots and mount your trellis to that, each plant has its own trellis and can be freely moved if need be.

yeah. something like this could work. but it’s more for support than spreading out the plant. i might try the 5gal with a hole in the top. or umberella holders to support some pvc frame

Its what I normally do. I find if you pop 4 canes in when you repot then you don't damage anything and it becomes fairly solid . You dont even have to use big canes, you can always tie wrap 4 more to the first ones if you need more height when plants have stretched.
You can add any sort of net to it or a solid grid if you see fit.
