View Full Version : Large & Mini module coli differences
12-13-2008, 06:55 PM
Hi everyone, first post, glad to have found "coli central" and be amongst fellow coli lovers :)
Following many years of dreaming about it, and following DDoc's and OG threads, I'm finally in a position to get my hands on a coli.
I was wondering about which configuration to go with, large or small modules?
Are there any differences between the two as far as the kind of media to fill them with or watering cycles? which is the more desirable to use?

Here is a part of a reply i got in pm from DDoc on Cannabisworld
The five two tiers perform better. Are easier to move, but take an extra inch of height(actually 5, one per module). I Have seen some very quick take downs and getaway with the two tiers and a cube van. Never lost a single plant. But the difference is the two row is more evenly watered then the five row. This leads to higher yields out of the two row. The two row is a better system but it costs another $xxx in Vancouver. So if money is tight then a five row is a better way to go.
Both can handle the same kinds of media, and media is the preferred method. In aeroponics i assume the two row would perform better. As DDoc mentioned the two row would be more evenly watered due to more watering lines per vertical bed covering less media.
I've never watered a five row so, can't comment from experience, but the upper rows dry out faster then the bottom rows, and this would be more exaggerated in a five row then two. Thus, ppms could accumulate faster in the five rows due to concentration by evaporation and ppm swing would need more management. In a two row this would be easier to maintain due to less of a vertical bed, also runoff is obtained quicker as the media only runs through two rows vs. five.

thxs much Nugg
it begs the question: how do you guys with the jumbo modules handle the feeding/irrigation issue so as to get the most even application possible from top to bottom of each module?........more frequent, lighter feedings than your mini module brothers?
