      <title>An API for plants</title>

      <description>&lt;![CDATA[This morning I discovered Trefle, an API for plants, through the r/hydro Reddit. What is exciting is that it does seem to cover a number of the variables I&#39;m looking to include in my growing spreadsheet:&#xA;&#xA;days to harvest&#xA;pH range&#xA;light range&#xA;temperature range&#xA;&#xA;There are also other interesting fields, e.g.:&#xA;&#xA;humidity&#xA;spread&#xA;average height&#xA;&#xA;Trefle gets its information from a bunch of sources, including USDA, Kew Royal Botanical Gardens, Wikimedia and PlantNet.&#xA;&#xA;While Trefle itself isn&#39;t open-source, it should always be free for open-source projects. Another alternative to consider, that is open-source, is OpenFarm.&#xA;&#xA;---&#xA;I’m publishing this as part of 100 Days To Offload.

      <content:encoded><![CDATA[<p>This morning I discovered <a href="https://trefle.io/">Trefle</a>, an API for plants, through the <a href="https://www.reddit.com/r/hydro/comments/ixf9ov/decided_to_make_a_idle_hydroponic_sim_of_sorts_i/">r/hydro</a> Reddit. What is exciting is that it does seem to cover a number of the variables I&#39;m looking to include in my <a href="https://gerritniezen.com/making-a-hydroponics-growing-spreadsheet">growing spreadsheet</a>:</p>
<ul><li>days to harvest</li>
<li>pH range</li>
<li>light range</li>
<li>temperature range</li></ul>

<p>There are also other <a href="https://docs.trefle.io/docs/advanced/plants-fields">interesting fields</a>, e.g.:</p>
<ul><li>humidity</li>
<li>spread</li>
<li>average height</li></ul>

<p>Trefle gets its information from a bunch of sources, including USDA, Kew Royal Botanical Gardens, Wikimedia and PlantNet.</p>

<p>While Trefle itself isn&#39;t open-source, it should always be free for open-source projects. Another alternative to consider, that is open-source, is <a href="https://openfarm.cc/en">OpenFarm</a>.</p>
