Starter Pots and Greenhouse Containers

About

Seed Starting Pots and Holders When starting your seeds indoors, timing them to be planted outdoors at the perfect size can be tricky. Unsettled weather and short growing seasons can make it advantageous to pot up your seedlings before they make a move to their final home. Being left in cell trays or pots that are too small will stunt the growth of your plants . They will run out of soil space and may become root bound before you can transplant your seedling outside. How to use seed starting pots Our 2.5” seed starter pots can be directly planted into or used as an up-pot for seedlings grown in cell trays . Many growers will start with this size and then either up-pot into our 3" pots or 5” pots or directly transplant the plant into their outdoor growing space. Check out this helpful video, How to Repot Tomatoes for Bigger Better Plants | Up Potting Seedlings , where we show you how to up pot from the 2.5” seed starter pots into the 5” pots. Do I Need Inserts for My Starter Pots? No. These are optional components, but they are handy. The 2.5” and the 5” can be purchased with or without inserts designed to fit the 1020 tray. These inserts not only make bottom-watering easier, but they also make transport easier. We recommend pairing the 2.5” pots with these 32 cell inserts with a shallow 1020 tray without holes for the best fit. If you are not using the insert, 1020 deep is a great choice, too. The 5” pots can be bought separately or with an insert and paired with 1020 deep without holes . Why plant seeds in small pots? Using smaller containers to start seeds has a few notable advantages. It saves space, soil, and water while waiting for seeds to germinate. It allows you to plant multiples of all your seeds and select only the strongest starts to pot up. Individual pots can be moved around for better light and airflow. Pots can be moved into the hardening off stage as each plant is ready rather than moving an entire cell plug tray.
