You are on the right track...
here have one or 2 piks for motivation...my xmas Misty blue, and what you can do in a 10g tubbler...pik2 is of Misty Blue clone in DWC. both clones were rooted and then planted the one in my special orchid mix, and the other in a 10 gallon tubbler

both were grown using ROwater...3-part,...Hygrozyme,...
Liquid Karma,...Humic Acid,...and BudBlood/BigBud, superthrive. I might've had some VooDoo juice at this time also...I haven't been able to afford that all year though
under a 1000w hortilux

I hope you enjoy, and realize that you too can grow plants just llike these...peace
