Grow is looking great!
How do you like those hydro halos? I have one on my FBT2201 as well. I've not hooked it up to a pump yet. I just ran the tubing up a stake, stuck a funnel in it, and pour my irrigation into it. I'm planning on using a pump later but it's pretty nice to hand water with as well. That fat tubing holds quite a bit.
If I could pick your brain a bit on the halo setup?
How many halos do you have going or is it just the one?
What size pump are you using?
How do you control the pump? Timer?
Do you use a ball valve to control pressure and flow?
I was planning 3 halos all manifolded off a 185LPH pump on a timer with ball valves. I think that's a correct setup. Just need to test the timer in minute increments and see what volume it actuall puts out.
