Should I transplant?

She has only just begun growing and to transplant her now would cause immense stress. You have enough room in that pot for 3-4 weeks growth. Wait until she has 4-8 leaves/nodes. Also, she does not need any type of cover, only cuttings/clones need extra humidity due to not having any roots. Your plant will grow fastest if you don't cut any leaves off/defoliate. Each healthy green leaf you remove will reduce your plants capacity to produce energy, slowing growth and resulting in smaller plants too. Defoliation as an idea should have died out with the dinosaurs as it provides no benefit to your plant, only detrimental trauma .So, please don't be tempted by the dinosaurs, all plants need maximum leaves for maximum energy production and for maximum growth. It is plant science 101. Try to only remove yellow leaves, for by the time they are yellow, they have served their purpose. I have been growing for 35+ years and have yet to see any plant that gets rid of its healthy green leaves. Yellow leaves yes, but not green leaves. If you are keen, check out some of my diaries to see how plants grow without ever having had even one healthy green leaf removed, just as mother nature intended. Sorry for the de-leaf rant, I just can't help myself at times! Hope this helps.,,... Organoman. P.S. - what is that black wire going into the pot??
