I will watch this grow closely.Your WW grow was impressing and i want to grow with DWC and HS1 too but Im still a bit to paranoid.
I wonder if you use just tap water for top off watering?
Was planning to use a R/O because I have hard water,too(0,6ec) but now i see your great results on the WW and i think i will try it first without R/O.
Please show us your LST techniques for dummies like Medgrower said.Thank you!!!
