![]() ![]() Increasing vapor pressure deficit (VPD) resulted in half the Ball-Berry slope and double WUE for AA compared to FA leaves. Scanning electron microscopy (SEM) images showed that leaves grown under aerosol exclusion in filtered air (FA) were lacking the amorphous, flat areas that were abundant on leaves grown in ambient air (AA), suggesting salt crusts formed from deliquescent aerosols. Here, the possible direct impacts of aerosols on physical and physiological parameters of camphor (Cinnamomum camphora) were studied (i) in a greenhouse experiment using aerosol exclusion and (ii) in a field study in Taiwan, comparing trees at two sites with different aerosol regimes. Such additional water loss is not accompanied by a wider stomatal aperture with a larger CO2 influx and hypothetically reduces water use efficiency (WUE). Deliquescence and subsequent salt creep may establish thin, extraordinary pathways into the stomata, which foster stomatal uptake of nutrients and water but may also cause stomatal liquid water loss by wicking. Major parts of anthropogenic and natural aerosols are hygroscopic and deliquesce at high humidity, particularly when depositing to leaf surfaces close to transpiring stomata. ![]() The distribution of different particle size fractions differed between and within species and also between leaf surfaces and in waxes. Significant differences were found between the plant species tested. Separate gravimetric analyses were performed to quantify PM deposited on surfaces and trapped in waxes. 'Acerifolia', Tilia cordata Mill.), three species of shrub (Forsythia x intermedia Zabel, Physocarpus opulifolius (L.) Maxim., Spiraea japonica L.), and one climber species (Hedera helix L) that are commonly cultivated along streets in Poland to capture fine, coarse and larger particles from air. However,further knowledge on species effectiveness in air purification is essential This study compared four species of tree (Acer campestre L, Fraxinus excelsior L, Platanus x hispanica Mill. Planting trees and shrubs as air filters is a way to improve air quality in these areas. The grow mats are not only organic, compostable, and 100% plant-based, but they also help the seeds water themselves.Particulate matter (PM) is an air contaminant in urban and industrial areas that often exceeds limit values, creating serious problems due to its harmful effects on health. We have 2 patents pending on this design. For ours, they're included at no extra cost. Other kits charge an extra $30-40 for a "premium" grow tray. Although this material costs us 3-4 more than the alternatives, we felt this was worth it to keep plastic out of landfills. We opted for a premium bamboo-fiber PLA plastic. 3 individual trays allows you to stagger their starts, ensuring you can enjoy more variety and with maximum freshness. We opted for smaller trays that yield 1-2 servings at a time, and reduce the inevitable wastage the results from using large grow trays in a small household. ![]() We tried and tested every microgreens kit we could get our hands on when we were developing this product and set out to address the shortcomings of the other options.
