perlite is perlite mate
if your doing another a grow in the future i would use the 2g it will pay you back in yield specially if using perlite (as its dead space so a bigger pot should be used)
if you only had 1.5 g of soil just roll the edges down to that an extra .5 of a g will help or use some perlite or coir could be used to bump up the extra needed
I dont actually use organic soil just organic nutes
I will be trying some on my next grow though
Thanks I do plan on using the the 2g for my next grow. Right now i'm a little short on cash so i'm just trying to get by with the minimum while still producing decent yields. I hear great things about Blue Mystic but haven't really heard anything about Gnomo. Guess i'll see
