i use TechnaFlora myself. in fact i started with the very same starter kit. the sugar daddy is, in my experience, not a necessity. they recommend it for everything yet don't include much of it in the package -- when you run out you run out. as far as the BS Boost goes though you might check your local grow shop and grab an extra bottle of that for later on as it is used in both flower and veg. and the Boost IS important to the recipe. you can probably even subsidize the sugar daddy with just a Tsp of Cane sugar and 1/2 tsp of epsom salts per 10 gal. that's what i did and my lovelies are just looking lovely.
