Thank you ;)
This is my first culture
So you say a little stress. Would you advise me a particular technique? or is it better that I do this on feminized seeds?
Use some garden wire. And use it to bend down your main stem. I'd also use another from the other side to help reduce the stress and pulling on the root system! Let it grow sideways enough till your happy with the new main cola number! Cheers and happy growing!
