Hey
Narn,
Just saw your thread browsing through the forum. I'm following you buddy, as I'll be growing some of that Watermelon myself in the near future together with a couple other Barney's genetics.
That being said...
with that grow
Oh and if you still have that third seed I would germinate it using this guide and replace the seedling with that little monster in the back of the tent. Experience dictates most of the time a dud is a dud, only on rare occasions does it turn into a Swan
Regards,
Bob
