If you can afford a proper Ph pen you are better off. Those drips are ok to start with but if you want to work you Ph as your experience grows then they are not accurate enough to fine tune like that.
Zandor Reviewed by Zandor on . is it ok to turn fan off for 6 or 12hour dark period? hey guys i switched my lights on 12/12 5days ago is it ok to set a timer on the fan so the fan turns off for 5hours when its dark then comes on 2hours b4 lights come back on? i guess it would be wise to keep the fan on when the plants are buddin but they wont be for a few weeks so wont hurt will it?? :rasta:... pps heres a pic of my unwanted males.. but i planted double seeds so all is good:dance: Rating: 5
