View Full Version : Which way to cut Blue Drums
19th April 2010, 14:54
From all the pictures i have seen it would seem that everyone cuts the Blue Drums on their vertical axis. Is there a particular reason for this. I was considering cutting mine on the horozontal axis giving 2 round geds approx 600mm across by 400-500mm deep. My plan was to have the outlets located in the centre of the drums. Woudl this cause any problems?

I have never tried it except for a few that I cut and planted palms in. the obvious disdvantage is smaller growing area and therefore extra costs. I have thought of trying it though for bigger plants in AP and also easier mounting of the half drums as growbeds. Can anyone who has tried this post some photos/feedback?

Simple matter of surface area available verses volume of GB. i.e.
Vertical (0.8m x 0.6m = 0.48sq.m.) and Horizontal cut (3.142(0.3x0.3)= 0.28 sq. m.)
Pros: Rectangular plan shape for planning, easy to do, better cross sectional shape for drainage, good depth at centre for siphon, easy for loop siphon, easy for continuous depth flow.
Cons: Have to support cut sides to prevent pressure bow-out, some edge protection may be needed for 'cut' edges (bit of split hose).
Pros: constant GB depth, self supporting cut rim, square bottom exit for drainage fittings.
Cons: Less surface growing area per volume, may have 'dead' (anaerobic) corners/spots for drainage.

Have to agree with others, will loose too much surface area. I used a circular power saw and followed the line down each side TFE.
Here is photo of mine, I used 20x40 pine timber between each bed, a lot easier to assemble and level. Just use hex head screws through the plastic into the timber, I used 5 each side.
I have mine connected to the one syphon.

While I have mine connected through the bottom via "loop siphons"... which have run flawlessly for close to 4 years...
