hi im about to re pot a couple of plants into bigger pots ,there about 12 days old and coming on nicely ,only prob is they have stretched quite a bit due to poor lighting for the first week ,there not falling over or anything .i was just wandering as im putting them in bigger pots can i fill the soil higher up the stems to make them more stable etc or will the stems rot or anything ??
yes twice. you can bury the stem, but it's possible to get rot. i've seen many people do it with no problems. move the light closer.
