First off welcome to the group! secondly Flora Nova is a great product just make sure to follow the directions for the veg and bloom. If you can't afford a PPM meter you will have to make sure to change your res frequently(at least once a week) Secondly many people use rockwool which is great but I recommend organic starter plugs because they do not have to be soak to adjust PH and makes it that much easier. Also what type of lighting do you have? Make sure you invest well here. Also get a small fan and a thermometer as well. Good luck and happy growing!
