Transplant when dry ONLY, it encourages new root growth because the old soil is dryer then the new soil, a wet soil will break apart and weights alot and the unsupported weight can damage the fine roots, water as normal after transplant (I always water with a brewed tea of bat/worm castings) If using bags cut the bag and get black nursery pot as they are easier to transplant from, i use a keg cup after cloned and go to a 1 gallon then a 2 gallon then use a 3.89L as a my finisher, my plants finish out @ 4-5ft. I usually trans plant lke this
I use a large kiddy pool for transplant work less mess
take your larger pot put a layer of soil deep enough to bring the level of the plant the the water rim in the pot, you can check by placing the potted plant in the larger pot
next remove potted plant with a little sqeeze and a tap on the rim with a screw driver handle, the pot should fall to the floor rather easy,
set the plant in the kiddy pool for a moment, take the old pot that fell on the floor and put it in the new larger pot and fill with new soil till you reach the water rim, remove old pot from new pot thats is filled you now have a perfect transplant hole put you plant in the newly prepped pot
now poke your fingers around the perimeter a few times ( I do 4) you dont want to pack it entirely you do this to stabilize the plant till finished filling, now add enough soil to fill the pot, now gently drop the pot on the floor a few times to pack the soil, when i say gently i drop it maybe 1-2 inches
