Plastic vessels in the form of clay pots or bowls are used to a greater extent, after initially being rejected. The cooling caused by evaporation of water in porous clay pots with their possibly. The plastic pot does not have any adverse effects on the roots. The dewatering is of course greater; one should prefer products with perforated walls to those without recesses or choose lattice pots, to achieve a stronger aeration of the plant material.
Foam pots can gain a certain importance for orchid cultivation. Their high porosity results in an increased temperature of the ball of the pot compared to the clay pot. There is no cooling through evaporation on the outside of clay pots and cannot have a negative effect on the roots. A small disadvantage can be the low weight of the pot. Especially if STYROMULL is still used as the main component of the plant material, larger plants tend to do so easily, to fall over.
Slatted baskets have the advantage, that the air can have a strong effect on plant material and roots on all sides. This naturally leads to drying out relatively quickly, which, however, should not be rated negatively. The plant material stays healthy longer, the supply of moisture, on the other hand, requires increased attention. It can be done easily, that the plant material appears to be too dry on the outside, however, the inside is still moist enough. These opposites are balanced out with copious injections. It's beneficial, to allow sufficient moisture to be supplied to the baskets at certain time intervals by dipping them in containers with water. In summer heat waves, that require ample ventilation, the baskets can dry out completely within a short time, without them being sufficiently moistened again by watering or spraying.
What wood the baskets are made of, is of lesser importance. Choose wood that is as hard as possible and has a durability of at least two years. The use of oak is obvious. However, tannic acid that drips off from hanging oak baskets can be perishable for the plants underneath. Sometimes the orchid roots are also damaged, which is to be avoided at all costs.
