anybody else?
i have another problem id like to get advice about./ i get this white powdery film on top of the soil and the drain holes in the grow bags i have i can see it too. seems like everywhere thats exposed to open air gets it. is it salt buildup? someone told me that could be the cause and i flushed but its still there. ill take pictures when the lights come on. i havent really noticed it effecting the plants in a negative way but it just doesnt seem normal.
