Early 2025 GG4 and White Strawberry Skunk

I germinated White Strawberry skunk a few weeks back, and it suffered from a bit of cold stress, but now it's recovering really well after putting it in a lit box. GG4 was very quick to germinate, about 36h in wet paper towel and 36h in soil, and now it already has some small leaves. I'm planning to improve my LST techniques and maybe do some mainlining this time around. I'm also hoping I 'll build a bigger box by the time I flip them to flower, as the one I use now is a bit small for 2 plants.
