it depends,if theres ANY cannabis at the same location as the grow equipment this is just cause for the confiscation of equipment(grower has exhibited intent to distribute cultivate or otherwise profit from the production of cannabis)...if theres seeds,grow lights hydro equipment in the same place as long as the seeds show no sign of germination i THINK your ok..but i'm not a lawyer...and if the cops were to see all that equipment in one place without a good excuse,i think they'd at least have reason to seize and give the property a right good search...dont forget all a cop needs to do is see someone with growlights enter an address,then SAY they can smell cannabis and that is probibly enough to warrant a search..remember lose lips sink ships!!..always be extra carefull..never tell anyone anything..good luck!
