First i dig a 3" deep cup bigger than pot bottom
Next fill with kickass soil.
Get plant out and put in place. This is me just checking roots, thought a pic was in order.
Start filling in around your purdy gurl with care.
That first mound gave me a hard time, this is one step i repress my lazy patient grower and execute this step as best as possible. Bit of OCD with music helps.
Next install your lights and wham! 2022 here we go!
I let the mound settle overnight, check it for cracks in the morning. Then fill cracks or whatever needs doing, pin hoses in place, and finally a grass mulch.
Good luck all.
