50 gal is way to big for nft. i did a 40 site with a 28 gal res and 2 pumps. it's basically a recycling system so your not going to use that much of your rez between nute changes. if your using 2 rez you can probably go with 18-20 gals each.
Could you imagine how great it would be if/when all of our politicians get their heads out of each others oily assholes, change the laws, and we can all buy seeds/clones at our local dispensaries or whatever.

Amen to that bro!!!!!:bigjoint:
make sure you put some of the peat back over the seed hole. your floros for seedlings is perfect. i use the mh for veg and hps for bloom but i don't know if it really makes a difference or not in veg, but def in bloom. your seeds should pop in a couple more days. welcome to the wonderful world...
