Hi
i thought maybe you would have registered a domain that had obvious relation to the terms in the title.
as is, though i know what the phrase means, the acronym for it hasn't been used as much.
so, either you're ahead of the game or chose a name with an obscure extension that may be hard to resell.
still, to the subject, i own a few which could fit in the niche`
www.SeedBasket.com < because you can't grow without seeds.
www.GreenFriendly.com < i think this speaks for itself in the green world
www.HardscapingDesign.com < this relates to the area surrounding your agriculture
www.GreenAdditions.com and
www.GreenImpressions.com < both are brandable for indoor or outdoor green concepts.
Good Luck!
imo...
