Hey what's up diggs99. Glad to see someone trying LPA. I have been growing with LPA for the last six years and will never go back to anything else. As per my user name ASSOG. AreoSystemSeaOfGreen. I grow in the sea of green. When I first started i tried every tub or toot (whatever) out there. Except the black and yellow ones from H.D. And they all leaked. I tried everything and nothing would stop it. So i finally tried the black and yellow ones and they worked great. No leaks. But I painted the outside of the lid white. As for how tall, it doesn't matter. No matter what the roots are going to go to the bottom. You just have to make sure the roots don't block your drain hole, cause they will . Now for your net pots. I use 3 inch net pots with 3 inch neosprene incerts. Everything else will get meldew and mold or leak. With your manifold use 1/2 inch and set it about 3-4 inches from the bottom. This helps with leaks and it still covers the roots good. I use only 9 sprayers. You have to remember this is LPA not HPA. our droplet size is to big, so less is better. So this brings up pump run times. I started with 1 minute on every 5 minutes. I am now at 20 seconds on every hour. Remember this is LPA. less is better. What happens with longer run times is due to the droplet size being so big the weight of the solution ( droplets) weights down all the little root hairs into one big glob. Which im sure you know is not good. Also like some people were saying res. and solution temps. are very important. You can get away with 70 but 65 is better. Just make sure you use hydrogaurd or something. In 6 years i have never had root rot ( knock on wood). I'll tell you something this is the easiest and fastest way to grow. And once you get everything tuned in yeild is comparable with every other way you can grow ( per s/ ft) if not better ( per s/ ft). This is how i set mine up. Each areo has 23 grow sites,two areos 46 grow sites in a 3x3 area under one light. With one res. You may want to cut your four areos to one res. down, do to how many different strains you want to grow. Cause you know that they all won't finish at the same time. And it's a big pain in the butt, if you want to flush. Like i stated i grow in the SOG. I take 46 clones, in 5-7 days i have roots. In areo cloners. I wait 17 days then straight to 12/12. No veg. Depending on the strain I'm pulling anywhere from 17 gs to 35 gs per plant. Do the math, in 9 s/ ft that's pretty damn good. There's not to many people pulling that per s/ ft. Anyway sorry this took so long. And good luck. You won't be sorry for trying LPA. Later ASSOG...............

Hold the phone

So u are saying ur getting over 100g per sq foot?!?!?

(46x(17+35/2)= 1196/9= 132.8 grams per sq ft


Hate to call bullshit but...BULLSHIT

I am impressed that you could do the math. :)
The whole post was kind of a mystery to me.
Also with a lot of bro science in it. But it's a free world, so everybody has to believe what he wants.

Theres been alot of crazy numbers thrown around RIU lately lol.


Do anyone have any advice for making a viewing port on the end of each tote that i can open and close/ keep light out and water in etc.... I was thinking of just cutting 3 sides of a window/door and scoring the bottom part so i can flip it open, just not sure how to close it back up so it can do its job but also be reopened again.

I guess i could use gorilla tape and just tape around the hole, it would be a pain when i wanted to open it tho, as that tape leaves a pile of residue.

@Airwalker16

you guys got any tricks up your sleeves that could remedy the situation?

I made a 'cork' kinda thing for mine.
I cut a hole the size of my funnel out and glued it to same material, but a little larger of a piece...so the piece that was cut out goes back into the hole and the larger piece keeps it from falling in.
Hope that makes sense...lol

If its just to look inside on occasion try using a door peep hole thing...easy to cover with a piece of tape :P

When I switch my system around. I was going to cut about 4” of the tote lid on one end ,hinge it so I have an access hatch. But it may make the lid a little weak not sure. Was just gonna use duct tape for the hinge.

Ya i tried this on an old lid and it def lost alot of rigidity .

Im gonna just drill a peep hole at the end so i can view the roots ocassionally, ill also prob drill out another 3" hole in the lid, above the drains, just in case i need to access it to remove roots.

So what i was going to do if it sagged like you said it does is just screw some plstic pipe as beams around the hole.On top i guess would be the best.

Ya that could work . I seen one dude did something similar, only he also used the frame for a scrog net above each tote.

So the pvc acted as a support for the lid and the plants.

You could use a PVC / ABS cleanout fitting, or a pressure test plug, or the rubber cap with band clamp style end cap/plug. All come in the size(s) you'd want.

Use a set of mpt and npt pvc fittings to give you a slip pipe opening to put one of the temp pressure test plugs in, remove it to inspect (for example).

Have to say that about every thread I find on custom builds usually end up with roots choking out the system and you'll find a later post from OP on root rot.

I think root rot has nothing to do with a DIY-build.
Plants get sick, or they don't.
There are circumstances that can 'help' but plants growing in a custom build set up...? I hardly think that this can be one of the reasons.

Facts show that the environment you provide for seeds with good genes ... just to mention that the builds work great until the roots 'choke' so consider it when building.

Perhaps I misunderstood.
But what is the difference between a DIY-build and a plug&play set you buy in the shop?
(except the price and the fancy looks)
But I mean for the enviroment you provide?

The plug and play, fancy ones come with anti root-choke features.
