Hi there DWCocha. Nope I've actually a 200 Litre capacity flexi tank. The flexi tank has a pump in it which continually recirculates water from the tank into the chiller back into the tank again. The 8 x 15 Litre water capacity DWC buckets are hooked up to an 80 Litre per minute air pump.
I've some insulation arriving as we speak for my DWC pots so the water temperature will be a continuous 18c or about 65f, so nice and cool, plus loads of oxygen and circulation. So I think that's all good.
Air temps are about 20-27c and humidity is still low (still waiting on this darn fogger, which should arrive tomorrow).
I've got 5 Litres of 17.5% H2O2 and in the near future I'm going to start using UC ROOTS when that comes into the UK. So the place is going to be completely dialled in and completely sterile.
