  • Cultiwool 6" x 6" x 6" Block w/ Optidrain and Donut Ring (48 Blocks/Case): Cultiwools' growing blocks are unique in the most efficient way. That has everything to do with the consistency of the products. Quick and easy uptake of water and the homogeneous distribution of water throughout the substrate are one of the most important features of a growing medium. Not only can you expect the highest quality stone wool in the market, but Cultiwool is also the first to introduce the 'donut ring' for the retail market to even further improve water distribution. This is in addition to the highly appreciated cross grooves to improve water flow under the block, and the black/white foil to prevent algae growth. The Cultiwool substrate blocks are provided with drain grooves at the bottom to improve the waterflow under the block. This is especially useful when the substrate blocks are placed on cultivation tables and concrete floors. Another benefit of the drain grooves under the block is that it will limit the contact surface with the ground. This will avoid bringing deseases in to the plant through weak roots often in combination with too high temperatures. As first in the industry, Cultiwool will provide the substrate with a donut ring as well, a water chamber around the plug hole to place your drippers. With the donut ring you will achieve an even more homogeneous distribution of the water throughout the block. A welcome second advantage is that you can not make any mistake anymore with the positioning of the drippers in the block.

    Just what I wanted.
    Color: Black, Navy Blue, Wine Red, Size: 5X-Large
    These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

    Its alright
    Color: Black, Size: 5X-Large
    True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through). There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).

    Fuzzballs get wearing once
    Color: Black, Size: X-Large
    Very smart to wear, but the quality is terrible so after one wash the collar start fraying and fuzzballs start forming. Very disappointing.
