Don't the Rubbermaid bins collapse from the weight of the gravel / hydroton and water flooding and draining? Or are these the heavy duty black stock tanks? Richard, what did those cost to ship? And where did you find them?
I'm wondering if anyone here has used Sure to Grow media either for starts, rooting, or media for an ebb-flow system? I've been trying pargro sheets of 98 for germination but I really hate handling rockwool. I stumbled across the website for Sure To Grow media, which is filled to the brim with praises for their own genius. :P
There are some nice claims for it being inert, pH neutral, sterile, and not leaching BPA. It's not biodegradable but it can be recycled. It won't irritate skin or lungs. It holds 82% water and 18% gas at saturation. It has very little wicking/capillary action so you have to flood your plants to the level of the roots or they'll dry out. Supposedly it releases nutrients more readily than rockwool...
Anyway, those are all claims from their own website but I haven't found much third party discussion of it except in the cannabis forums -- not necessarily the most reliable source... a lot of the complaints sounded like the growers weren't following the directions unique to this product.
So has anyone tried it? Any of you vertical growers? Does it deserve the hype?
2x12 frame with plywood bottom, lined with 1/4" mesh reinforced ferrocement. Bombproof and more susainable over time and has kept my highly acidic (below 6) water buffered at 7.6 max. It's a good amount of work, but well worth it.
Sylvia Bernstein said:And I'll be the first to ask a question...what are people using for grow beds? If you stick to the 12" deep rule there just ain't much out there. We raised our hydroponic flood and drain trays using plywood and pond liner, but that was a massive pain in the backside. What are you using?
Any recommendations for indexing valves currently have 3 grow beds and would like to increase to six I would run out of flood tank water without increasing the sump, I have no room for a larger sump I would like to try indexing valves but have never used them or know where I can purchase them,
Ok, I just got the go-ahead. I can supply the Aquaponic indexing valves here in the USA, if you are in OZ contact Rupert.
AQUAPONIC LYNX LLC
I only just got the basic site up and it will be improving. I intend to provide custom design and installation of systems here in the Southeast as well as carrying some unique products. I don't want to be a direct competitor with Sylvia.
