Tank volume<\/strong><\/p>\n\n\n\n The ideal tank volume depends on the size of the wall. As a general rule, a larger reservoir makes the system more stable and less susceptible to fluctuations in nutrient concentration and pH. Common guidelines suggest 5\u201320 L per m\u00b2 of wall area. With a wall size of approximately 4 m\u00b2, this results in a recommended minimum volume of around 80 L at the upper end of the range.<\/p>\n\n\n\n Daily water consumption under artificial light is typically 1\u20133 L per m\u00b2 – for 4 m\u00b2 that means 4\u201312 L per day in theory. In practice however, consumption on this wall has consistently been closer to the lower end at around 4 L per day, giving a realistic autonomy of roughly 20 days at the tank volume used.<\/p>\n\n\n\n Tank Used: 85 L Flat Tank from Tanksdirekt<\/strong><\/p>\n\n\n\n The tank chosen is an 85-litre flat-profile tank with a flush-mounted lid, sourced from Tanksdirekt.de. Several practical factors influenced this choice:<\/p>\n\n\n\n Form factor:<\/strong> The flat profile was a deliberate choice \u2014 a conventional upright tank of the same volume would be too tall for the space available beneath the wall. The tank fits precisely underneath a table, keeping the entire system compact and contained within the room without requiring a dedicated utility space.<\/p>\n\n\n\n Living room compatibility:<\/strong> The tank has a clean, unobtrusive appearance that is acceptable in a living space. It is not a utility barrel or an agricultural container – it does not look out of place beneath furniture.<\/p>\n\n\n\n Transparency:<\/strong> The tank material is not fully transparent, which is actually advantageous \u2014 it limits light penetration and thereby inhibits algae growth in the nutrient solution. It is however translucent enough to allow the water level to be estimated visually without opening the lid, which is useful for a quick daily check.<\/p>\n\n\n\n Workability:<\/strong> The tank material is easy to drill with a standard hand drill. Bulkhead fittings for the supply and return lines, as well as cable entries for the pump power supply, can be installed without specialist tools. <\/p>\n\n\n\n Lid access:<\/strong> The flush-mounted lid keeps the profile compact and allows the pump to be installed and removed directly through the lid opening. <\/p>\n\n\n\n Autonomy & Holiday Operation<\/strong><\/p>\n\n\n\n For a 1\u20132 week holiday the volume is comfortably sufficient in terms of water quantity alone. That said, it is still advisable to top up with osmosis water before an extended absence: evaporation continuously concentrates the nutrient solution, raising conductivity even when the water level has barely dropped. Topping up before leaving stabilises both the fill level and the nutrient concentration and reduces the risk of fertiliser burn accumulating while unattended.<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Tank volume The ideal tank volume depends on the size of the wall.
