I also use fox farm ocean n have seen the best results in veg with around 50/70% humidity with the occasional rise with watering around 80/90% humidity is fine as long as it don’t stay that way temp is a little harder plants like cool temps with there hot temps I’ve personally seen the most growth between 65/75 Fahrenheit higher a bit is ok no higher then 90 in a tent it will suffocate your plant seedlings n sprouts need to be kept warm including there soil a heat mat is perfect for this the seedlings do need more humidity around 75/85% preferred
