Flushing In Perpetual Harvest Grow?

[Skunk Baxter]

I'm using a General Hydroponics Waterfarm 8-pack, and I'm planning on switching to a perpetual harvest in a couple of weeks after I harvest this crop. I'm planning to buy 4 more modules, for a total of 12. They'll be hooked up in series, and I'll harvest 3 modules every 2 weeks.

Trouble is, the only way I'm going to be able to set this up, I'll need to run all 12 modules off the same reservoir. Which means I'm not going to be able to flush before harvest, unless someone else has some idea on how I can do it with the setup I described. Anybody have any suggestions on how to flush 3 of my modules when all 12 are running off the same res?

you need another res thats not going to work optimum

by hand lol.

Yeah, I don't expect any good news here. The way my area is set up, there is a way I can add a small second reservoir, but it's going to be extremely complicated. Long story, it'd take too long to explain it. It's just the way the doors and the room are configured. I just figured, what the hell? Post the thread, and maybe some Mr. Wizard will come along with a brilliant solution that nobody else even dreamed of.

Help me-e-e-e-e, Mr. Wizard....

no need to flush.

With GH nutes you can try using Lucas Formula for SOG. He only uses one res for SOG, 8ml micro and 16ml bloom per gallon, no Gro. ppm ~1300. He gets nutes back up through add back water and only flushes once per cycle.

I've actually been kicking that idea around myself. Thing is, I'm just not sure how much of a difference it will make. See, I'm really new to hydro. I've been an outdoor guy all my life, and all the indoor grows i did when I was younger were done in soil. So I just don't have enough experience to know how much of a difference it will make to not flush 'em. You think it won't be much of a problem?

Now that's an interesting-looking thread. Thanks! I have the feeling I'll learn a lot when i read it tomorrow. I'm too loaded to make sense of it tonight (but don't tell anyone. I can't remember if that's allowed here, and I don't want to get in trouble.)

I'm not using GH nutes, though, I'm using Humboldt. Does that make a difference for the purposes of this discussion, or is that something I'll learn for myself when I study the thread tomorrow?

 

[Santos L Halper]

It might, the thread is in the context of using GH micro and bloom. It is still pretty interesting so I'm sure you'll be able to get something out of it. I thought you were using GH nutes but I see it is just your setup, my bad.
