That's good news, ideal environmental conditions are hard to achieve. Good work zoning in the right levels for these seedlings. The one upfront looks ready for a topping now, back left is only a few days away too. Good luck, thanks for sharing your plants and strategies.
KiG cheers
I think another day or two and I should be able to to get in there to top. It's to tight right now for me to do it without messing up.
