Zillions & Zillions of Springtails in no time! Extra Premium Springtail food is an all natural complete diet for springtails. It provides carbohydrates, trace minerals, & proteins that are essential to the growth & production of springtails. Our powder comes in a shaker container to make it easy to add to your cultures. Just sprinkle a little on top of your charcoal or soil once a week. 4oz by volume. Large, bulky & heavy items may require a little extra shipping. We will contact you if your order requires a shipping adjustment. You may also reach out before hand for a custom shipping quote. LARGE , HEAVY & OR BULKY ITEMS MAY REQUIRE EXTRA POSTAGE Due to Esty’s platform being relatively basic & primitive on the shipping options, Etsy is not advanced enough to allow the option of assigning a different shipment rate for each item variation. We deal with mostly natural items & they all vary DRASTICALLY from unit to unit in size & weight. For example, the cost to ship a small piece of wood may only be $16 dollars but the XL may cost $60+ to ship. We will over up to an additional 10% of the shipping fee, & contact the buyer with any difference needed to ship the item(s). The buyer will always have the right to cancel for full refund if the shipping difference is more than they are willing to pay.
