Light cover design help -- The Perfect Sprayer?

First off does anybody know who makes the perfect sprayer. One that has a fine mist like the hand pumps but the ease of the big gallon yard sprayers that you pump up by hand. Or just a place to get the proper tip I want. Modifications? Ideas??

What I bought was one of those round-up gallon yard sprayers but you have to pump it up to get the pressure to get the spray I want out of that brass nozzle that came with it, and when the pressure drops a little it gets to be too heavy of a spray. So I want a finer spray from start to finish. So I need a new tip or a better sprayer. Not a small hand held pumper but one with a wand so I can reach back in there to spray my plants.


Also want to ask if anybody out there has a good idea for making a light cover so I can spray my plants and not get juice all over my lights and spot up my glass. Any ideas for this??

Something I can make that you will just hook one end on the light and flip snap on the other end so I can spray my plants.

What I have thought of and tried is using cardboard and magnets to stick to the underside. The magnets ended up being to small to hold the cardboard up. So that idea may need to be re-modified.

What I am thinking now is getting some plexi glass and making two wire hooks on one end of the plexi glass to hang on the light and then some velcro straps to secure the other end so I can spray.

Sound easy but with what I have going on know you have a small area to work in. Imagine you open your door to your room and you have string running across it four feet high then plants sticking above that. Then a small area and then your lights which are raised up all of the way. So you will have to get the cover in there and then move under the string so you can reach out and secure the cover to the light so you can spray.

It was difficult trying to see if the cardboard idea worked without messing up my plants. I didnt mess anything up but dont want to either and I dont want to do this three times like I always do.

Maybe instead of hooks I can make a channel and glue it under the glass on the frame to slide in the plexi glass into it and then velcro the other side to hold it. Sounds easy.? never is. I need something I can use for a channel. ]

My room is 7"x7" and I use the 6" magnum xxxxl hoods. I also need to make a cover for the 4' 8 bulb T-5's for another room.


Any ideas?
Any pics if you have done something like this?

TIA

You could use two channels, one at each end and just slide the Plexiglas in. That way it won't swing down and decapitate your plants. Lowes and Home Depot sell a plastic channel used to hold plastic lattice into vinyl fences. You might find aluminum channels they use for storm windows if you want metal.

I came up with this for a sprayer.

It only takes me a third of the time to spray my plants compared to doing it with the just the small hand pumper. I get better coverage with the finer spray, I can get more control out of this so I use less product A WHOLE LOT LESS and makes really very little mess compared to before. I may not have to build a light cover now on top of it.

The pics speak for itself on what is needed. That green ring with the threads needs to come off. I used the corner of my bench grinder and took my time and ground it off till it broke the rest of the way. On the black plastic tip with the brass piece, I cut off the very end so it flows straight out and not to the side. The tubing is 5/16'' ID. Put it together, taped it up so it doesnt catch on my plants. Done.

The new and improved model using 1/4'' tubing. I found out that the mulit purpose roundup in the green box has the same plastic tip I needed. I put the tubing in the black tip first after I tried to heat the tubing under the faucet and it was hard to do but it finally went on. Thats pretty much it.
