Im growing 3 - Dream N Sour's from seed right now, its only been 4 weeks and I've topped them already. they only took a few days to recover, and boy do they grow fast! I'm sure it has to do with the sativa genetics.
they stink! I've got the 3 seedlings growing in a small 3x3 veg tent with 4 other plants that are 8 weeks old - these plants do not emit a smell...but these 3 tiny Dream N Sour seedlings are putting out a smell that is noticeable with the doors closed!
They take more nitrogen than the others also, I had to feed these seedlings a lot sooner than other strains I am growing.
My advice:
plan on topping them early, even before they show you signs of sex or else they will out grow your area.
get your odor under control and have air freshners, carbon scrubber or other odor eliminators ready
give them small amounts of nutes around week 3, and they will stay bright green and happy
good luck!
