I have grown the dog a few times now. Never used reverse. It will do 1 of 3 things (that I have found), it will either produce 0-1 ball (have had a few push out one... give me 15 or so seeds). They will spit a few balls the first few weeks, in this case you can pick them all off with some patience. Last option will be them being strait up he/she's with half the plant showing girl parts the other half balls. I've only seen that a couple times and each time from seed, clones don't do it.
Haven't used reverse ever, sorry. This is all the help I could offer.
