I had a seedling i planted on a small peat pot, once sprouted i planted the whole peat pot inside a medium grow bag i got from a purchase, with some MG organic soil only to test out, well i never fully buried buried the pot so the so the roots came out the bottom and deposited at the bottom of the bag and roots, to make a story short i took i out the bag and broke the soil off while spraying it with my kitchen sink sprayer till i got all the soil out the roots..
planted in new pot with MG organic / perlite / sand slowly packing the soil into the roots till fully covered, gave it a good watering with ST and its been a full day with no droopiness showing. Only thing is the whole process took over an hour, mostly on breaking the soil from the roots.. hope this helps..
