@Seedsman, I've always had a good success rate with blowing up the bag like that I feel it gives a little bit of space between the plant and the top of the baggie with the moisture sometimes you'll have those little sprouts grow like crazy and blow through the napkin and I'm always worried that if I don't catch them in time the little leaves will get some kind of rot from the moisture from the top of the bag so when I blow it up like this it gives me about an inch or two of space plus the extra oxygen I feel helps with the germination process. I checked them several times a day can't help it very impatient but I also change out the air in them too at least once a day I'll get a better picture of this strain to show you what I mean if it goes like that the pineapple whip I also am doing in this grow sp like I don't even know I've never seen anything grow that crazy
