Gen 1 Clones are great to test in your production and to supplement your clone inventory. Gen s will be in and out of stock based on rotation, and custom orders are available. Will be anywhere between 4-10" tall for proper shipment. 
All Gen 0s & Gen 1s will be rooted and hardened before they are shipped.
