I am courious about this as well. So if i read this right. In the the beginning and through veg, it helps with roots and leaf growth and then in flower it helps to ripen the "fruit". So keep a piece of carpet or cut leaves in the veg cab. The issues with the flower room is it helps to ripen the fruit faster. So you have to time it right to get the yield you want then put it in to ripen it. Now someone like my self a continues grow, My clones, mothers, and plants vegging are all in the same cab. So adding the carpet or cuttings will be no problem. The flower on the other hand will have multiple stages going on so unless i set up a seperate room (not possible at this time) i cant do this for the ripening. It does seem interesting though. I am planning on moving my grow to another part of my house due to the fact it is in my closet in my room. Kinda hard to have women over to spend the night with ou having to answer questions or freak out. SO i might be able to try the ripening thing in the future. Just thought of something, is this gas used during the day or night? If night when i take my plants for harvest, i pull them out of the flower room and cover with black plastic for 48 hours. Would that be enough time? You know take them out of the flower give the plant a bit of carpet and then cover it up? I wonder if that would be enough time? Sorry if i am rambling I'm just a little stoned right now.
