More than that does not speed things up and only uses up your syringe faster.\"}},{\"@type\":\"Question\",\"name\":\"The plastic cap came off in shipping. Is the jar still good?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Usually, yes. The plastic flip cap is only a dust cover. The sterile seal is the rubber septum held down by the crimped aluminum ring underneath it. If that ring and the rubber are intact, wipe the septum with alcohol and use the jar as normal. If the aluminum seal itself is loose or the rubber is missing, don't use that jar and contact us.\"}},{\"@type\":\"Question\",\"name\":\"Why is the liquid amber instead of crystal clear?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The broth is a nutrient blend of malt and sugars, and it picks up a light amber tint when it's sterilized. That's normal. What matters before inoculation is that it's see-through, not cloudy or hazy.\"}},{\"@type\":\"Question\",\"name\":\"Can I inject the same jar more than once?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. The lids use the same self-healing septum found on medical vials, so the rubber reseals behind the needle each time. Wipe the port with alcohol before every entry and the jar stays sealed for the life of the culture.\"}},{\"@type\":\"Question\",\"name\":\"Why can't I draw culture out of the jar?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Pulling liquid out of a sealed jar can create a vacuum that fights the syringe. The vent needle is optional and only needed if that happens. Wipe the port with alcohol, push the small 25G vent needle through the septum so air can get in, then draw with the 16G needle. Pull the vent needle out when you're done and the septum reseals. Do this in a clean, still area, since the vent lets room air into the jar.\"}},{\"@type\":\"Question\",\"name\":\"How long does a QuickCulture jar take to colonize?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Most jars are ready in 5 to 10 days at normal room temperature. Slower species, older spore syringes and cooler rooms all push that longer, so judge by the growth in the jar rather than by the calendar.\"}},{\"@type\":\"Question\",\"name\":\"Can I use a liquid culture syringe instead of spores?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. Injecting 2 to 3 cc from a liquid culture syringe works the same way and colonizes faster than spores, since the mycelium is already established.\"}},{\"@type\":\"Question\",\"name\":\"How much grain will one jar inoculate?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"At 2 to 3 cc per quart, a fully colonized 30 ml jar carries enough culture for roughly ten quart-size grain jars or bags. Draw only what you need and keep the rest sealed.\"}},{\"@type\":\"Question\",\"name\":\"Do I need a stir plate?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. The jars colonize on their own with an occasional gentle swirl. A stir plate simply breaks the mycelium into an even suspension, which speeds things up and makes the culture easier to draw.\"}},{\"@type\":\"Question\",\"name\":\"Do the jars arrive sterile and ready to use?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes.
