Each 125L tank in the flowering area is dumped and cleaned 2x a month. I use 400ml each of the Canna Flores 'A' and 'B' when mixing a new tank (yields 1400ppm), so each flood system uses 800ml nutes per mo.
There are other necessary consumable items like 50% grade H2O2, which I apply at 1ml/litre, so 125ml in each tank, normally every 3-4 days but can be applied weekly. I also put 1tsp Epsom Salts and 10ml of Canna liquid calcium in each tank when mixing every 2 weeks. A 2L jug of pHDown lasts several months, requires about 20ml per tank when mixing, perhaps 10ml per tank in between dumps.
There's some other expenses in hydro like nutrient and pH meters, which are sort-of consumables. Good pH meters (I use Eutech pHScan1 meters) have a replaceable probe tip; these last 2 years. I have a Truncheon nutrient meter which is now 7 years old and going like a champ, but that's longer than mfr Bluelab's estimation of the service life of the device. I can't recommend Bluelab's pHTruncheon meter. I have had 3, all croaked in weeks. You also will want an aquarium air pump and air stone for nutrient aeration. Air pumps last about a year, some come with a replacement set of pump diaphragms and flapper valves, good for another year's use. Common aquarium air stones, made from essentially glued sand, don't last long in acidic nutrient solutions. Use bubble curtains made from plastic materials. Look hard and you will find some bubble curtains with a porous poly sleeve with a woven stainless steel core, which weights them down to keep them from floating. This sort can be used for a couple of years with occasional cleaning with a scrub brush.
Hydro is indeed a bit more expensive than soil, but the benefits far outweigh the costs, which in the end are usually reasonable if you shop well for your hydro supplies- do comparisons between local shops. Some hydro shops are treated like cash cows by their operators- you can spot these jokers with their 1 litre bottles of H2O2, repacked with a house brand name and priced at $20-25. So's ya know, I pay $5/litre for 50% grade H2O2 in 25L jugs and could get it cheaper if I bought more qty... Make sure you shop around, especially online, to get a clue if your local hydro shop is clipping you.
