A foldable trellis device in accordance with the present invention includes a predetermined trellis configuration having first and second symmetrical portions with substantially similar dimensions and design features. The foldable trellis device further includes pivoting connecting elements to pivotally connect the two portions to allow the two portions to close such that front surfaces of respective first and second portions become engaged, or to allow the first and second portions to manually positioned to vertically resist gusting winds. To increase the stability of the foldable trellis device when wind gusts are relatively strong and from varying directions, a stabilizing member is pivotally connected to the first and second portions to form a wind resistant configuration when taking a top elevation view of the foldable trellis device.

The invention is directed generally to improvements in irrigation and fertilization assessment and delivery. More specifically, embodiments of the invention provide an improved fluid delivery tube, method to manufacture such tube, and systems that include such tube. The delivery tube is beneficial at least because it minimizes the life cycle cost of a responsive delivery tube.

A water purification apparatus comprising an injection molded floating non-toxic, biodegradable, and recyclable polymer planar structures that are easily stackable, shippable, and connectable to as many companion units as the user desires; such apparatus further comprising many receiving structures made to accommodate plants without inhibiting them so that the user may create a film of plants over a toxic body of liquid for bioremediation purposes.

A embossing tool consisting of a mandrel and embossing assembly.

A cocopeat substrate and its manufacturing method, includes the steps of: (a) mixing raw materials, part by mass, of 70-75 parts of cocopeat, 0-0.5 parts of pH regulator, 0-0.5 parts of rooting agent, 25-30 parts of modified diisocyanate and 20-35 parts of water uniformly by a mixer to form a premixed material; (b) immediately filling the premixed material into a mold and carrying out hot press curing to obtain a cured cocopeat substrate; and (c) drying with hot air to remove excess moisture, and then air cooling under room condition. The cocopeat substrate has an EC value less than or equal to 1.0, a pH value of 5.0-6.5, a porosity of 80-85%, and a density of 0.18-0.25 g/cm.sup.3. The cocopeat substrate has a truncated pyramid structure and a planting hole functioning as a natural planting pot with slow natural decomposition rate, readily for use directly for growing seedlings.
