I have been researching hydroponic systems as I would like to perform some research on plant additives and/or colorants and wish to have a medium-less type growth system so that A) I do not have to account for nutrient content of the soil, etc, and B) hopefully I can achieve faster growth / more experiments with respect to time.
I intend to build this myself as its mainly a curiosity at this stage. I need the system to be very compact with respect to height as I wish to have multiple systems in pods / trays, running different mixes of additives. The majority of information online is geared to a 'specific market', where space or the height of the pot does not seem to be a concern. Regardless I performed quite a bit of reading anyway to avoid asking but seem to find that most of those allude to 10", 5 or 10 gallon containers etc, which are a bit tall for what I am after. In my case footprint is less of an issue than height.
There are soo many types of hydroponics now available, (i.e. DWC, RDWC, continuous flow, flood and drain, etc) and other techniques (i.e. aeroponics, aquaponics etc), that I am unsure what would be easiest to produce on a small scale, DIY.
So my questions are;
A) what would you suggest would be the easiest method to produce and run reliably?
B) what would be the shallowest pot/vessel/container/tank that would work well? - I do have the option for a separate reservoir if that was required, as I would like to avoid daily maintenance if possible.
Any other tips or assistance you can give will be most appreciated, thank you.
