Awesome thread!
I want to convert from soil to dwc, and thought hempy would be a good place to learn, just have a few questions if anyone cares to answer..
I have fresh bottles of GH 3 part nutes.
And buckets full of 100% perlite ready to rock and roll!
Firstly, can the Lucas formula be used in hempy? If so should I need to add anything else? Silicon, cal/mg ect? Or does the formula provide enough?
Second, if Lucas can't be used, will using just the three bottles of GH as base nutes supply everything the plants need?
(I've never used
proper bottles nutrients before)
Third, why hasn't anyone tried using an airstone like other hydro methods? I get the point of hempy is to draw air down through the perlite as the water drains, but wouldn't adding oxygen keep the nutes in the res better for longer? Would also make the perlite dry up faster and force seedling roots to hunt for water faster
yes.. no? I'm just brain storming here.
And lastly, what's the go with ph? Test it, don't test it? I would test it.. but my pen just broke so if I don't need to check ph I won't bother buying a new one.
And another quick one, I thought OC+ realises it's ferts according to temps? Not wether the soil is dry or wet.. if I can get a 100% sure answer on this I wouldn't mind trying the osmocote way aswel.
Thanks to anyone that's answers my questions.. happy growing guys!
