Growing plants from plugs
I've often been fascinated by hearing people speak of growing plants from plugs. Are these just for commercial growers or can a home gardener order plugs. I just was looking at the Harris seed website..and saw where they sell plugs/liners. What are the liners for? My understanding is that when a home gardener orders plugs they are shipped in packs and then you replant them in larger pots like 3 or 4 inch. nursery pots until they are large enough and weather favorable for planting. Is my assumption correct? How do you find out if the seed company sells plugs to the home gardener? Another question I had about buying plugs is that if plugs are grown "under lights?"
