| Why are pots typically wider at the top than at the bottom,デュベティカ ダウンジャケット
Recently I needed a pot with shape that would make it as stable as possible so that it's unlikely to tip over and fall from the shelve. Seedlings in soft trays are another story,http://duveticavestesfr.halod.com/, you can squeeze the sides and bottom to get it out. Also, stability is more a function of width vs height (low center of gravity is better) than shape. If you stick a 6 high plant in a pot with a 6" diameter base,Parajumpers Jackets Outlet, it will tip over regardless of shape; but a 1 high plant in a pot with a 1 diameter base will not tip over unless you have a very determined cat. bstpierre Oct 28 '11 at 13:27 With ceramic pots,Duvetica Down Coats, I imagine it's easier to get sloped sides cleanly out of the mold when manufacturing. This may be true of some plastic manufacturing,ダウンジャケットメンズ, too. When transplanting,jordans shoes sale, it's easier to get the plant out,デュベティカ ダウンジャケット, complete with all the soil,discount Parajumpers Jackets, if the sides are sloped. For seedlings,デュベティカ 激安, the reduction in root hair damage may also be significant. Once it's free from the bottom,Duvetica Jackets UK Outlet Duvetica Down Jackets For Men Store, there's no contact with the sides,デュベチカ 通販, if you pull out straight. With a cylinder,Duvetica down jackets, the soil is scraping against the sides all the way up. If the sides are really slippery, like most plastics,デュベチカ専売店, this doesn't matter too much. This makes the most difference when transplanting seedlings,デュベチカ 通販, and plants where the pot is still larger than the plant needs. For seedlings, the reduction in root hair damage may also be significant. At the other extreme,http://rogerviviershoesoutlets.blogspot.com/, larger root-bound plants will usually hold the soil together regardless of pot shape. As for styrofoam seedling trays which are often cylindrical - the shape is certainly a problem for me. The higher friction of them makes getting seedling out of them cleanly a lot harder than with other materials. The shape compounds the problem. Tried them,ダウンジャケットメンズ, didn't like them. They're probably fine for growers for whom the seedlings are always root-bound before transplanting. The compression tries to press the vessel into a sphere,デュベチカ専売店. If you try to create a cylinder with ceramics the firing compression will squeeze most strongly right in the middle causing it to break,デュベティカアウトレット. That's why it's so hard to make ceramic pipe and most historical ceramic pipes where not true cylinders,Duvetica Jackets Outlet. Creating a conical shape creates some usable cylindrical space while directing the compression force in a strong circular vector that works something like an arch,デュベティカダウンジャケット. 相关的主题文章： http://www.yangxinqi.com/share/ http://mggym.com/mg/viewthread.php?tid=509929&extra=page%3D1&frombbs=1 http://ask.ichety.com/forum.php?mod=viewthread&tid=406536&extra= http://www.xiashahot.com/ http://www13.plala.or.jp/gakuki3/cgi_bin/aska/aska.cgi http://blog.wangyu99.com/blog.php?do=showone&type=blog&cid=1&itemid=4157693 http://www.citysun07.com/bbs/thread-12103173-1-1.html http://www.portfolk.fora.pl/koncerty,1/archimedean-property-and-real-numbers-spun1,6247.html#6699 http://datrip.cn/news/html/?358281.html http://www.jianouren.com.cn/ http://www.pitchcountcalculator.com/node/1#comment-239445 http://ns4.freeheberg.com/~flc1978/index.php?file=Guestbook http://www.kelunpu.com/plus/view.php?aid=304025 http://class3081.com/forum.php?mod=viewthread&tid=265642&fromuid=295 http://yclama.com/thread-720689-1-1.html |
