I want to transplant some of my babies from soil to a DWC system. My question would be; what would be a good age to do so? They are between 1-3 weeks old right now.
i start mine in soil and move to dwc and i transplant withing the first month when they are big enough to handle a little stress and there isnt a massive root ball to fight with
Just experiment . Part of being a grower is to experiment and to see what works.
