Thanks :) Was I still using drip rings I definitely would have used valves, but as it stands the drip rings are out. I really have to update these drawings! /\/\\/\/

Thanks, I used SketchUp. /\/\\/\/

New thread with a broader overview of the system (including canopy layout): https://www.rollitup.org/grow-room-design-setup/607609-my-latest-project.html /\/\\/\/

This thread is an overview of a new rig I'm building. Here are a couple of (outdated) images to start: As you might have noticed, this is a 4-site vertical grow using wire fencing as a trellis. The tent's dimensions are 120cm × 120cm × 200cm. A traditional lamp-over-plants method would...

I've already purchased the air stones. They work extremely well. I think you mean "Pondmaster". In any case, I'm not using an Alita air pump. I'm using a no-name Chinese thing (Jebo) that gets even hotter (probably). Why? It's what I can find locally. Ideal? No. But it worked just fine last...

Thanks, the drawing has come a long way since my first post, as has construction on the system. I've been too lazy to keep the thread current but I will make a concerted effort to bring it up to date someday soon. With regard to some of your points: • I decided against a drip ring after...

True story: A friend of mine with limited access to his remote garden asked for my help with unattended watering. Automation for him is subject to the following conditions: a. He wants yields to meet or exceed his current expectations. b. He eschews complexity c. He lives on a shoestring...

I've considered using risers to get gravity into the game. Problem is that I'm growing vertically in tents so the higher I raise my plant containers the more surface area I lose. I may I'll start a new thread soon with diagrams so you can visualize it. /\/\\/\/

I'm not quite sure what your question is exactly. Sketchup is free for anyone to download and use. There's also Sketchup Pro, which costs money. I used the free version. As it happens I'm an experienced graphic designer so I have a slight edge on the uninitiated, but anyone with a little...

Black PVC in what application? Pipes? I'm just using what I can source locally, and that's standard grey, 75mm PVC. The 3D models were built in Sketchup. The flat schematic was made using Google Drawings. ]-[

Hey, Nitro, As it turns out I may have to abandon this design and go with a Multiflow / Ebb & Grow setup this time 'round. Whatever the case, I'm going to plumb my RO system directly into a plain water res, which will top off the nute res via a simple float valve and flow volume meter. Thanks...

Right now the control bucket's location is restricted to the confines of the tent in which the system is contained. I could move it out if I raise the containers so that the drainage pipes are level with the tent's lower openings. Or I could cut new openings. Or I could pressurize the return...

Cool. Aeroponics is not up for consideration at the moment. Thanks for the kind words. The schematic was made using Google Apps Drawing. The 3D image was made using Sketchup. \\ /\/\ \/\/ \\

Hey, thanks for the reply. It seems to me that, given a system volume of about 100 liters (like this one), a 2000-LPH pump will circulate the water in 20 times an hour, so I'm unclear on what you mean by "recirculation would be minimal". I intend to use airstones in all the containers. A)...

Hi, folks, Here are a couple of evolving illustrations of a Waterfall/Top-Feed Recirculating-DWC system I'm designing: Schematic: Sketchup model: I'm personally drawn to the idea of a pressurized feed line for a few reasons: a) I can take a top feed to a drip ring which will allow me to...

Correction: My RO water reads 72 µS, not 72 ppm. Sorry for the confusion. I'm correcting my original post. /\/\\/\/

True, I'll mess with adding some tap water back into the solution to get my Ca & Mg. Where did you get the 100 ppm figure? /\/\\/\/

Where I live we have, if anything, an excess of minerals in our tap water. My best-case RO scenario is a reduction from ~740 µS1 to 72 µS1, of which the remaining parts are (judging by the buildup in my kettle) primarily calcium. I take that 72 µS1 into account when I calculate my EC. notes...

I apply a neem oil solution regularly and inspect just as frequently. I'd be surprised if any pests got through. Good thought, though.

Good point! My understanding is that the Lucas formula is a full-cycle nutrient, and accounts for the nitrogen balance in the solution. I'd figured that with a low EC (~550 µS) I might encounter some deficiencies but I didn't think I'd burn anything. Shows what I know. I'm gonna try reducing...
