Outdoor Oscillating fan in a greenhouse?

[Think]

I'm growing some Think Different and was wondering should I use a oscillating fan in the greenhouse and shall I still use it in flowering ?

Hope someone can help me

better air circulation and if your greenhouse gets humid that would help stop mould developing in flower, i dont see a downside to having one aslong as it isnt too strong.
i dont know greenhouse specific reasons though.

Has your greenhouse got automatic opening windows at the top?
Mine has and I just open the door in the day for a through wind, probably a better option bro

Yeah I'm worried about mould! and hell it gets hot in there at times so a fan is on the cards! well I have found a battery fan with different settings so I'll be buying that tomorrow, just wondering when should I start putting the fan on my seedlings? and should I put it so it's blowing over the top of them ? and shall I keep it on the canopy throughout the grow?

 

[Think]

No it hasn't :/ it's a cold frame so that isn't an option but I don't really want to keep it open becuase of the dogs and random visitors, I keep it open a little bit but I'm going to try a fan and go from there!

The best thing to do is get circulation going.. When they are young ones dont have the fan directly on them, have the air bouncing off a wall (glass in ur case) This helps the stems thicken up ready to hold the weight of the buds.. In full flower have them fans blowing rite on the plants it will help reduce the risk of mold too :key:

Right okay I will do that when should I get it blowing on my girls ? and because I'm in the U.K it get get around 11 C outside and around 15C in the greenhouse when it's its cloudy like today should I still use the fan ?
