These narrow "Cone-tainers" allow for considerable plant growth in a small space. The tall, cone-shaped design and internal vertical anti-spiral ribs let roots grow deep and straight. Each individual cell has a center drainage hole on the bottom and four side-drain holes on the tapered end.
SC7 cells have a cell diameter of 1.5", a depth of 5.5", and a volume of 107ml or 6.53 cu. in.
SC10 cells have a cell diameter of 1.5", a depth of 8.25" and a volume of 164 ml or 10 cu. in.
I use a custom substrate for growing Dwarf Citrus Trees so this might not fit all situations.
As a tool for growing and developing root systems of freshly germinated seedlings, the cone trainer system functions perfectly.
Transplanting from the cone trainer system is more of a slow and dirty process. I would like a better tool than a dowel for removing a seedling plant from the cone. This becomes a huge problem when you are managing hundreds of seedling plants at a time.
My racks are in a shelf storage system. I have to modify two trays by plastic welding to make a bottom tray that will fit. Would have loved a tray that is 16" x 25 1/2"
I bought these for starting Am Chestnuts, Dunstan Chestnuts, black locusts, black locusts with purple flowers, thornless honey locusts, acorns, and moringa seeds. The containers are quick and easy to fill. I potted up most of the sprouted chestnuts about 3 weeks ago. The tallest are now about 4"tall, but most are only about 1 - 2" tall. These containers should encourage a nice central tap root. I also love that these take less growing medium to fill. The only downside is that they only have 1 diameter. For the larger Dunstan chestnuts, it be nice to have a slightly wider diameter. Great buy though! I would buy it again!
I use the cone tainers and trays to start pine trees because they are hard to find in quality due to all of the fire restoration in the PNW. The deep roots established in these containers help the seedlings survive the hottest part of the summer with no supplemental water. I get at least 80% survival if I give the seedlings a year in the cones and plant in the spring. Far better than bare root stock.
Product arrived quickly and works well for seedling starting
I simply cannot fathom why any company went to this length and NOT include some form of propagation dome / covering with enough height to cover tree cuttings! This is such a sad oversight, and although I can make one myself, I am also a business man and would strangle someone offering this product from my business without having thought this through.
Absolutely the best container I've spent money on!! Great root development, plants are growing healthy and strong
Conetainers were okay but not easy to get seedlings out of. Also not made in USA.
I use these cones for a variety of uses...from sowing large seed rare conifers, to rooting rare cactus cuttings, to potting up cactus seedlings...used in conjunction with the germination trays, bottom watering is regulated and safe from over watering.
