Brick Built Grow Shed (mold)

Hi there, i previously had a grow shed until the contents were stolen.

since moving to a new property i now have a brick built shed, in which my plants are now in flower.

they are fairly tall over 1.3m, im pretty sure they shouldnt be this tall.

however this is not the problem, the problem is it seems mold is forming

i currently have a 600watt HPS light, i have an office fan to circulate air and to increase plant strength, a 150mm hole for fresh air to let its self in, but i do not have inlet or outlet fan.

it is outside, so what would you suggest?

a dehumidifer? inlet fan? outlet fan?

anyhelp would be brilliant, i have put bowls of salt to trap moisture

Exhaust fan first and foremost.

That hole is not going to let much air in if you don't have a fan letting air out.

I should have added that if you exhaust air you also exhaust the humidity.

Where is your mould forming? On your buds or in the shed itself.

there is white dust forming on the plants, ill give that a try then! thanks mate

White dust is likely powdery mildew.
Ya... exhaust fan will be your first step... if that doesn't help.. then you'll want to look into a de-humidifier as a second step.. that will usually rectify most problems with humidity.

i have just purchased a fan, which i will attach some flexi ducting
so we shall go from there!!

What size fan? What size room?
If you are doing it - you might as well make sure you get one that fits your needs.
