Hi, guys so I've germinated a few autos and they,ve poped up, I'm doing a seed run and hoping to catch the end of session outdoors (UK) I've brought my distilled water, silver,battery's and clips as I'm spraying one (cs)Lady to produce pollen to pollinate the rest, now I've heard that TDS don't read the ppm of colloidal sliver ? Can anyone shed some light on that from experience and recommend a testing device that will measure the ppm, the lady's are only 3day post pop up so I've got 2 to 3 weeks to figure this out , any help or info would be appreciated. Good look growing guys & girls
