Seedling Air Circulation

Eagers
Eagersstarted grow question 5 years ago
Im growing seedlings indoors in a window (they are only 7 days old) but ive been wondering at what point do the plants start needing circulating air? Found limited answers online, they will be going out to greenhouse once theyre big enough but for now do they need a fan?

All you need is a small fan to make sure fresh air is moving around the plants. When they are out in the open fresh air circulation is a little less important. The bigger benefit to air circulation is blowing a gentle breeze over the plants to strengthen the stems so they can hold more weight. Literally all you need is 1-2 6inch clip on fans for cheap. I bought 2 off amazon for like $12.

Hey friend, I usually keep at least 1 hole in my cups over the seedlings to keep some air exchange, and also let them breathe for an hour or 2 each day. I wouldn't worry about giving them an active breeze until they've gotten a 2nd set of true leaves, so a few days,maybe a week. right now just keep giving them some quality light, the high humidity and warm environment. Even if you chose to wait until they got into the greenhouse I don't think that would be bad.✌️

Hey buddy ;-) You should definitely add a fan. But be careful not to blow the plant directly 👍

Le plus tôt possible avec une petit flux d'air pur commencer. C'est cela qui lui permettra de bien se durcir au niveau des tiges et branches :)
