I have some black nursery pots that are thin black plastic. Finally, although some people have success using PVC framing, others may need to use electrical conduit as framing if they are in a high wind area or in an area where snow or sleet are likely. I only had 12-14 inches of soil in the tub so the tub itself provided protection from the wind. Eliot Coleman's book is a good read. Fill it with tap water, and let it sit for a day or two to dissipate the chorine and allow the water temperature to moderate before introducing plants.There are many ways to create a tub garden and a multitude of plants and fish to select from, but for a thriving, low-maintenance container garden, the key is balance. One technique I learned from him was to use a frost blanket-type row cover on top of plants that then have further protection from a hoop house or high tunnel.
Line the pot or basket with two layers of newspaper to keep the soil from sifting out.

Wicking bed systems tend to favour soils that have high levels of organic matter and compost (generic soils found in garden centres tend to compact up and prohibit the capillary process) so it is worthwhile investing in good quality compost and potting mix. Also, the larger the structure, the easier it is to maintain the appropriate temperature because very small structures heat up too fast and also cool down too quickly. Many of the principles of gardening in water are the same as those for gardening in soil. -Roofs not extending sufficiently beyond exterior walls. Floating water lettuce or shallow-rooted watercress will live in a birdbath, and a clump of cat tails will be happy in a 5-gallon bucket. That's right--weeds.

The watercress uses these, and therefore makes the overall water quality better. Placing the pots where they will receive an hour or two of shade during the hottest part of the day also helps.When choosing containers, select ones made of nontoxic material, such as untreated wood, plastic, glazed ceramic, or terra-cotta. When you see watercress (Nasturtium officinale) growing in the wild, it's usually partially submerged in slow-moving water. Final spacing of seedlings or cuttings should be 8 inches apart. I think it was overkill. In the early spring, thinly sow the seeds 1/4 inch deep on top of the potting mix. -No "ice and water shield materials" installed on roofs in areas where frost is a possibility. Sufficient insulation in the attic will keep the attic cold in winter, helping to prevent repeated melting and refreezing of snow on the roof above. It was a very gnarly job to say the least.
Growing watercress from seeds is one of the more complex options but it is not impossible. Plant space-hungry cat tail, lotus, arrowhead, or water hyacinth in decorative containers, and arrange them to display their different heights and textures. Correctly sized and applied Ice shields won't let meltwater penetrate through the roof either. If the meltwater penetrates the roofing, it most likely will just leak through the roof at the overhang, just above the roof edge and gutter, and that meltwater will drop to the ground below, without causing damage to the inside of the structure. Plant space-hungry cat tail, lotus, arrowhead, or water hyacinth in decorative containers, and arrange them to display their different heights and textures. Grow watercress in full sun. LOLI'm no architect or roof expert, but I believe that Ice dams are due to bad architectural planning and practices and a general cutting of corners in the construction business. There are lots of books that will come up when you do a search on "Year-Round Gardening". I suspect the hardest part for me would be to build one that could handle the hard north winds.
