I noticed some white powdery stuff appearing on my clay balls in the veg cab over the weekend, ive managed to do a bit of checking tonight and i think it was powdery mildew
![Sad :( :(](/styles/smilies/icon_sad.gif)
It wasnt on any of the plants though just a few of the balls so i have removed the effected ones and replaced them with new ones. Ill keep humidity a little lower the next day or so and from what i read if i spray my plants with water regularly it shuldnt be a problem. Ive seebn a homemade spray also to get rid of it if it does get any worse.
While i was replacing the balls i saw what i though was mould around the rockwool cube!! On closer inspection it seems to be roots that have grow up instead of down and some of the have gone a bit fluffy is the only word i can think to describe them. Im pretty sure its not mould but ive taken a pic.
I just cant seem to win, i cant get the flower cab dry enough and i cant get the veg cab humid enough without virtually turning the fan off in there and the temp rising to 30!!!
