Congrats on the new dog mate!
It's always a special time when you can welcome a new member to the family!
I'm afraid I cannot give any information on the test strain yet, besides it having both Old School Afghan, as well as new school American genetics and that some phenotypes may show colourful shades and hues in the leafs and flowers. Shame you lost one out of 5, but still 4 healthy specimens to go, should be a fun grow to watch
Nice one mate! Solid options for the lights as well, If you have a 4x8 I would definitely choose with a good spread of maybe something with optional lights.
Have you ever seen the Migro Array series btw? Very good lights and with such a grow area you can go for a Aray-12 setup or a 4x Array-4 setup if you want more power/higher PPFD for example. This will probably be better than a single light like with the options you mentioned, especially with a single light source in a rectancular room the sides won't have the most optimum PPFD/PAR readings. Just a thought!
