hi hipro,

i used them in my current grow for the same reasons....see here:http://boards.cannabis.com/showthread.php?t=88772

i think they are god and wil use them again...seeing as ive got a pack of about 100! lol

when the time came for transplant, i gave them a good watering so the pots became soft, and pealed the pots of, and carefully placed the lump of soil into the main pots.

one thing to watch for is not to damage the roots, if the seedling is too large, the roots will grow into the sides and botton of the pot, making removal difficult or impossible...

the method i used was to gently rip the pots off, feeling for any resistance where a root might have grown into the peat material, and carefully work around it....so making sure the pots are soggy before attempting this is important.

an example of this, is one of my roots had penetrated the bottom part ofthe pot, so although i removed the sides, i planted in the main pot withthe bottom still attached.
