Ya i have a 1.5x1.5x4ft veg boxes to move them in and the box there in is capable of being two time its size due to the light fixture being moveable up and down
All the realy tall ones i rescued from a friends failed experement they were overly light starver for 3 weeks so they are really streached lo but the only plants im worries about are my two furthest along ones ie- 2nd and 4th pic
