Hey I was wondering how many pounds a 2x4 stud would hold if it was positioned lenthwise on top of a grow setup.
Depends on how long it is. Problem with supporting weight with wood is that it needs to be reinforced. No matter what you're working with, be it plywood or otherwise, it will warp over time.
You can support a lot of weight with 2x4s, but you've got to do it right.
Alright, It would just be one 600watt light system with a light mover and didn't know if I needed to add some more structure, but I think it's light enough that a 2''x4''x8' stud could hold it right?
Can you mount in on edge instead of flat? That should give you some added strength.
I'd make an I-beam out of 3 2x4's and 2½" deck screws. Solid as fuck.
Yeah I was thinking about just putting it on it's edge but I don't know If I have enough room since it will be snug against the ceiling with my plans currently but there's always time for improvements.
Hmm I know what an I beam is but I've only seen metal ones. With 2x4's would I attach the boards lengthwise with the two 4in side connecting to the middle boards 2'' sides?
2 boards horizontal on top and bottom, with a vertical board in between. 2½" screws along the length on both sides.
That is way overkill.
You can span a 2x4 eight foot and the weight of the light/rail and mover will not effect it at all.
We are only talking about 20-30lbs man.
alright it's good to have somone shine some light on this. I didn't think it would be a problem since I saw someone else doing it my way with only one 2x4, but they have a slightly different set up so i didn't know.

The 2x4 should have a natural bend to it. You can see it by looking down the length of it. Place the wood so that that bend makes a natural arch. It'll give you a bit more strength and prevent sagging.
That's not to say you need to keep a big 'wow' in the board. You can straighten it out. It's just a matter of deciding which side of the board to have facing down for the most support.
If the light and rail are 20-30 lbs and the rail doesn't add any structural support, you'll want to anchor the 2x4 to the ceiling or provide some other extra support.
