What are plasticisers (phthalates) and are they dangerous to my plants or me?
Plasticisers allow a hard plastic to become flexible. A few plasticisers are known to negatively affect certain plant’s abilities to breathe correctly. We do not use any of these compounds in our new models. The amount of plasticiser needed to affect certain plants is measured in picograms. Picograms are three orders of magnitude smaller than milligrams. This means three orders of magnitude below the maximum permitted levels set by governments for human exposure. Milligram (10-3g) -> Microgram (10–6 g) -> Nanogram (10–9 g) ->Picogram (10-12g) These minute amounts are so small that they do not even show up on a test for plasticisers if testing plastics for household items or children’s toys. Plants have attributes that humans do not. The minute levels needed to affect a plant will not affect humans. We do not have any of these plasticisers (aka phthalates) in our new grow tents.
