Thanks for the pics and input! I will look around coming weekend what kind of things I can find that are suitable for a DWC setup. Maybe at first just some (clean) styrofoam containers they use in here to transport vegetables or fish and make a small bubble system out of it. It gives me enough time to look around for something bigger while in the mean testing out various vegetables and growing conditions. However I will need to check the
nutrient temp buildup.
Do I need any special thermometer for it? I am not sure what the impact of the nutrient solution is on a "normal" thermometer.
About the bucket system: if I understand correct, in the lower bucket I place a piece of tube that will determain how much water will stay in the bottom acting as reservoir. However the top bucket will be above that level, so I assume I fill up the bottom bucket with hydroton pebbles so it reaches the top bucket? If not: please explain how the plant could wick up the solution.
How to determine the reservoir size? It seems to depend on the
Number of plants x
Bucket size x
Average uptake per day x
Ammount that keeps the
pump from running dry
