3.5" x 5" Deep Black Square Greenhouse Mega Pots - P86D

  • The 3.5" by 5" Deep Black Square Greenhouse Pot is a great size pot for cuttings and annuals, including tomatoes. Our poly-form line of pots provide the economy of a thermoformed container without compromising quality or durability. Form pots feature die-cut side/bottom holes for consistent drainage and are designed to fit securely in carry trays and pro-totes.

    Form pots are now manufactured with a new blend of plastic that greatly increases container pliability and reduces the likelihood of cracking or brittleness.

Great product

Nice size

The purchase from the website was great and shipping was very fast. I ordered these while on sale but paid full price overnight shipping (only option available) so I thought the value might be ok. This size of these pots are perfect for tomatoes and other long root seedlings. And, I like the design with the ridges, hole, etc., However, these are very thin and I was expecting them to be more substantial, similar to others I have received at the same price point. The reviews were so glowing. These seem to be a one season, sale pot. I am not sure if I will get two seasons from these. The value fell short in comparison to another company/pot I purchase. But, that company does not offer this deep pot. If I can get three seasons from them, the value will matter to me and I will purchase more. Also, I did not need FedEx overnight shipping. The company could offer a cheaper line of shipping options and the value to purchase would be better.


These pots are the perfect size for starting plants and vegetables in without having to worry about transplanting up to a bigger pot right away. For me they are exactly what I was looking for. I hope they never stop selling them. The quality is good as well.

Lots of room for roots

I bought these to pot up seedlings once they outgrew their original seed starter trays. I especially like the 5 inch depth for root growth. Seem to be sturdy enough for several seasons of use.
