I wonder where I can find that rubberized peat. I've been thinking of using fish gravel but its a bit heavy. I'm trying to set one up outdoors, but I might move it indoors for the winter. I never thought of using the plastic gutters for my growing bed, thats actually quite clever!
Well, according to J. Benton Jones Jr. in a book Hydroponics A Practical Guide for the Soilless Grower, p.28: "In order to avoid the hazards of either low or high temperatures, the roots and rooting medium should be kept at a temperature between 68 and 86 F. Reduced growth and other symptoms will appear if root temperatures are kept at levels below or above this recommended temperature range."
And about the maximum amount of oxygen in water depending on temperature, in 59 F it's 10.05 ppm and in 68 F it is 9,08, according to same book. So I would say that some evidence is needed for the claims of this guy in the video.
I mean that one-tenth increase in aeration of the roots is not worth it, because of the problems that lower temperature may cause. Improved aeration could be achieved using a different kind of delivery of nutrient solution to the root zone.
Good points. I don't have the technical grasp I would like to on every aspect of hydroponics. I'm not a chemist either, but I've built a lot of systems with students over the last five years and I've found that colder water always means healthier roots and the aeration, while it may only dissolve so much oxygen, keeps the tank cleaner and smelling less. Thanks for the info, though.
Great job on the video, Mr. Anderson! I certainly hope your videos will help increase the public's exposure to aquaponics and lead to an expansion of the field in future years.
Which do you prefer to grow in...hydroponics grow tents. We've found soil to be the best during arecent smaple/focus grat.

Some very nice videos, the audio is a little off, but that's just nit picking. Thanks for the uploads.

I like the point he made with the optimal temp of the water/roots. That's good to know.
