@gigglebush_ok: VIVOSUN 19L humidifier — that's 5 gallons, top-fill, and I run it from my phone over Wi-Fi. The probe reads the actual tent air, so it keeps the humidity steady without me having to babysit it, and I don't have to refill it every day. It also comes in 9L and 5L on the same link, so pick the size that fits your space. #VIVOSUN #19LHumidifier #GrowTent #TentHumidity #PlantCare
