My complete 4x4 setup

The brain of every tent I run. Automates temp, humidity, VPD, fans, lights, and CO2 from a single dashboard. Pays for itself in the first cycle in fewer mistakes.

Featured in the Controller AI+ video.

Thick 2000D fabric, observation windows, tool ports in the right spots, and zippers that actually seal. If you want to run CO2 or hold tight VPD, seal quality matters more than people admit.

Quiet, UIS-compatible (talks to the Controller AI+), and pulls enough air to keep a 4x4 dialed even mid-flower. Carbon filter handles smell completely if you swap the carbon yearly.

For a 4x4 you want 600-800W of actual draw, full-spectrum, dimmable, with a separate driver to keep heat out of the tent. Avoid cheap quantum-board knockoffs; pay once, run for a decade.

AC Infinity Ionboard S44 is a solid UIS-compatible option that ties into the Controller AI+.

Solves the dry-tent problem for good. Hooks into the Controller AI+ so it triggers on humidity set points instead of a wall timer. Quiet, refills are easy.

Once everything else is dialed, CO2 enrichment to 1,200 ppm is the next step. The AC Infinity regulator plugs into the Controller AI+ for set-point dosing. Pro tip: buy the tank empty online and swap it at your local welding supply for a much better price.

Reads moisture, EC, and root-zone temp in real time and feeds the Controller AI+. Takes the guesswork out of watering frequency in big fabric pots.

You cannot grow well without measuring pH of your water in and runoff out. Cheap pH pens drift; get a real meter and calibrate it monthly.

I ran my Ethos Genetics grow in fully organic Build A Soil. Top dress, water with rainwater or RO + minerals, and you skip the bottled nutrient hustle entirely. Soil gets better every cycle.

If you'd rather run coco or peat-based, those are valid too. Living soil is just what works for me.

Air-prune root system, no overwatering, easy to move. Five gallons is the floor for a flowering plant; seven if you have the space.

Wide catalog, reliable shipping, and they keep their freebies stocked. My partner code takes 10% off any order; reveal it on the promo codes page.

Best autoflower genetics I've run, period. Consistent phenotypes and fast cycles, great for a perpetual setup or a first grow. My partner code takes 15% off; reveal it on the promo codes page.

If you keep mothers and run clones, a dedicated propagation tent gives way tighter control than starting clones in the corner of a big tent. Faster establishment, higher success rate.

Pre-soaked rapid rooter or rockwool cube, clonex-style gel, and a humidity dome. That's the entire kit. See the cloning guide for the technique.

Cheap dollar-store pruners gum up in an hour. Buy two real pairs so you can swap when one gets sticky, and keep them clean with rubbing alcohol.

Hang whole branches in a dark tent at 60-65°F, 58-62% RH for 10-14 days, then move to wide-mouth quart jars at 75% fill. Boveda packs lock in 62% RH for the long cure.
