"Every once in a while you have to replace that wire whip because it breaks down. Well, where's that
plastic going?"
The cheapest machine on your line is the one touching every gram you sell.
Chuck Warner of STM Canna on the Growers MBA podcast.
2% transpiration per hour x 24 hours = a 48% dryback.
Start at 70% field capacity and you are at 22% by morning. Too far.
So you cut the target to 35%, and the irrigation window falls out of the math.
Shot size is the output, not the input.
"The longer the straw, the higher the EC, the more pressure on the root zone, the harder it is to suck that water."
Push EC past what the plant can physically move and you break equilibrium. It shuts down.
Liam Spenser (AROYA) on the Growers MBA podcast with Elliott Gorfain.
Watered his peppers daily. They stayed green all season.
Forgot them for two weeks. Every one turned red.
Easy conditions tell a plant to grow. Pressure tells it to ripen. That is crop steering, and your
room is doing one of them right now.
20 to 25% of what you pay for bulk growing media is freight.
Peat gets trucked down from Canada heavy. Loose coco ships its own moisture. Compressed blocks fix the freight bill and hand you a labor bill instead.
Coco coir has a high CEC. Great for holding nutrients, except coconut trees grow by the ocean, so it arrives holding sodium and potassium instead.
Flush it heavily with CalMag or it rewrites your feed.

Why is anyone still buying HPS?
Elliott Gorfain: it is cheaper at checkout. Then you replace lamps every 6 to 9 months, pay for
electricity that leaves as heat instead of light, and pay again for the AC that removes it.
You pay for the heat twice.

Growers ask us for the highest wattage they can get.
Elliott Gorfain: a 1,500W LED will not outgrow a 700W one unless your VPD, CO2 and feed can keep up.
The plants cannot use energy the room cannot support.
Wattage is a ceiling, not a result.

A grower bought $60,000 of grow lights and paid about $15,000.
The difference was utility rebates almost nobody checks before buying. Elliott Gorfain on the rebate most growers leave on the table.

Elliott Gorfain on why the margins in cultivation are a game of inches, on the Growers MBA podcast.
