bagseed genetics isn't always the best it is really hit or miss as far as getting something really good from them. I use ziploc baggies rubberbanded over the solo cups for germinating and then as soon as they pop the soil I pull the baggie off and let them fly under flouros. I have never had a problem with seedlings dying in droves. Only had one or 2 die on me in the past few years. That is pretty good track record if you ask me. Never killed a plant either unless it was for harvesting. IT is a weed it is as hard or easy as you want to make it.
