Barneys Farm LSD?

I have 2 LSD seedlings that are 17 days old which is only half the size of two other strains that are same age. Does the LSD grow slower? Could I have a bad batch of seeds?

LSD is a good stable strain it might be the environment that they are in

Yes, LSD developes slower, but catches up. The bud distribution is more sativa-like, with many smaller buds. In the end, I yield the same off of a grow of LSD as I did from a grow of GH's Great White Shark (which is considered a heavy yielder). That's 17 oz off of a 22"x22" megagarden. The high on the other hand is far superior to the Great White.

My LSDs grew completely different haha they were the biggest out the bunch for a long time until the sativas passed em up.
