I love your collection too Adam!
Wish I can grow the tree aloes here..too cold here in winter and have no more space for indoors. haay..
Yeah, I would think you may need to supplement lighting for your aloes if indoors in winter..unless you have a good wide south facing window.
From what I have seen with my succulents, it feels the seasonal cold change real well, so they wind down, grows much slower so not much to no watering is required. I think it is also the angle of light they get once placed indoors.
Since you have tree aloes..thought to share some photos of tree aloes I saw in San Diego last year, during Thanksgiving, so admired them! I thought the blooms were from a kniphofia, but on closer look..nope..from lovely Aloes! They are growing near the coastal side, in full sun, mix of good cool and warm temps there always...so lovely....in time your plants will mature and look like these ones!
