hi all
could someone tell me what my humidity should be in my flowering room
also what it should be in the veg room
cheers
Canna grows best with between 40 - 60% RH in vegetative growth and flowering, and that's the RH range you should be shooting for.
However, whilst anything between 40 -60% is fine for veg, you might want to drop that slightly for flowering, say 30-50% RH, due to the risk of mould and botrytis (bud mould) which thrives and multiplies at RH above about 50-60%.
RH isn't really *that* important in the general scheme of things, Canna will grow in 0% RH and 100% RH, but like temperatures, watering and feeding, there's always optimum levels to shoot for and your plant will always grow better and be more healthy with the correct temperatures and RH levels.
