<p>We are told that strength is resistance — that a good structure pushes back against wind, weight, heat. Thirty years of load calcs and twenty years of an organic garden taught me the other half: <strong>strength is absorption</strong>.</p>
<p>Clay under a greenhouse roof does not fight noon. It drinks it. It holds the heat in its lattice and gives the vines eight to ten minutes before the fan has to shout. Those minutes are the crop. The best engineering is invisible. Community work is the same.</p>

<p>Mix ratios, the 14 July lag log, the 140 CFM fan with a 15-minute intake delay, and the three ways the floor failed. Not a calculator. A sheet you can take to a Saturday workshop.</p>
