Look up things up like.. PPM, Soil PH Level and PPFD. For a first time grower you might want to use Advanced Nutrients PH perfect sensi grow, and bloom.
use zip jars, make sure not to pack to tight as to were there it ristricks air movement. keep the jars in pitch black, so the remaining chlorophyll dies off.
hope that helps!!
To know if they are ready you need to look at the trichomes... they need to be dark, opaque they say.. also flushing is always necessary prior to harvesting.. hope this helps!! :-D :-D
Look at my other post, just about everything is done by a remote aka receiver. All so just remember redundancy creates consistency. Have more then one fail safe..
If you get Cheap PH&PPM Pens you will get trashhh results in the end!! Just bite the bullet and get the better quality, it will pay itself off in the end. :idea: :idea:
