You might want to cut the number of sprayers in half. I think 4 would work for coverage if you can push the volume. Also, remove as many 90s as you can in your pressured line. It might just be that a bigger pump is needed. If you have some tubing left over, it could be a fun experimenting a bit. Looking good over here!
Thanks - that's good advice. I hadn't thought about the elbows having any impact.
I've ordered a bag of what I hope will be better sprayer heads, and it's funny you mention it, I'd already decided I probably only needed 4 per bucket. I've got a stronger pump on the way, too, so I'll play around with it until I get the spray pattern I want.
My 1000 W light came today, but the glass enclosed reflector won't come until Tuesday *pout*. I think the carbon filter and fan arrive about the same time. I started working on the exhaust today, anyhow.
The plants are under this 600W now, which I will move to the other side of the closet.
So, that light in the picture above will get moved to this side over the nursery buckets and connected to this tube:
Then I'll put a tube between the two lights and one from the new light to the carbon filter and its fan - gonna mount it up under that shelf so it gets the hot air.
After that I'm going to build a table to put those nursery buckets on top of so they'll be way closer to the ceiling and also so the reservoir for the big plants' buckets can go under it.
And then all I have left to do is build a door.
Interesting, but I suppose not really surprising if you stop and think about it, sticking the tube onto that exhaust fan brought the temp down in the closet 4 degrees. Can't wait til it's connected to the lights and really pulling a lot of heat out.
