I actually prefer jumbled up, bruised to already deflasked seedlings.
-All plants in flasks fare better for me (even the ones which got shaken)
-More than once, when I received predeflasked seedlings, they are contaminated & struggled (The only exception to that are pk seedlings from Glen Decker & Fritz Schomburg, the plants are great when I received them out of flask, I believed it was the result of a highly sanitary deflasking procedure & very speedy transportation. I received the plants next morning from the deflasking of previous day)
- Back to the question, Someone mentioned before that to spray the seedlings actually give you more damaged plants. I only wash the plants in distilled water. And if I am not lazy at the moment, I would pots the bruised ones together, so if contaminated, they won't spread to the rest ( This may have been suggested by Lance)
