ok then
i'll give you few tips to get it right. first and most of all you need good airpumps and airstones, you need the water surface to be well covered with bubbles, for your scale, you need an electromagnetic air pump with multiple outlets, the pump is a bit loud must not be insulated because it heats, so room noise is more of an issue, then get smaller aquarium pumps 2-4 outlets for the cloner and vegging plants, clone in a bubbler cloner, transplant in netpots with growrocks place in veg tubs then in flowering. you need to keep water temps down, around 68-70deg 19C it doesn't tolerate high temps well, good H2O2 helps prevent slime and rot but high temps prevent O2 to dissolve in H2O so plants will not be well. a res chiller is around 300$and more A/C probably same but requires more electric, this is where i lean towards flood n'drain, when i know i will grow in the heat, i find it way way more tolerant to high temps and that's because the growrocks are exposed to air, evaporation occurs, keeps temps at rootzones lower and better oxygenation and feeding. the cloner could probably go with no cooling except if it's bloody hot, but in winter will require a small water heater, that's quite cheap, durable and effective. keep spare pumps around, check them daily, check airstones very often, when they clog change them. that's where you should keep your eye with DWC, the details make a big difference. also chose a good dehumidifier for the room, see if it's available you can wait till you're in mid flowering to get it depending on bud size, if you managed to have them big, then you will need one
maybe not this season if humidity is low but eventually you got to get it, oh yeah get a humidity/temp meter
