Grow Lights Made Simple

Leggy seedlings, bleached tips, and a wall of PPFD charts that never answer the one thing you asked: how high do I hang this, and for how many hours?

  • The four dials that decide everything indoors (color, distance, hours, intensity) set for greens, herbs, and fruiting crops
  • Hanging-distance and photoperiod tables by crop and light type, so you stop guessing at the chain height
  • PPFD and DLI in plain words, with target numbers and a free phone-app method instead of a $200 meter
  • The 6 lighting mistakes with two-minute fixes, plus which spec sheet numbers are pure marketing

The 4 light dials

Color, distance, hours, and intensity are the only things you control indoors. The guide sets each one correctly for greens, herbs, and fruiting crops.

Distance and hours cheat tables

How far to hang the light and how long to run it, by light type and crop stage, so you stop guessing and stop burning or stretching your plants.

The 6 light mistakes (and fixes)

Leggy seedlings, bleached tops, the 24-hour-light myth, and chasing lumens instead of PPFD, each with the exact fix.

Indoors, light is the one thing you fully control and the thing most growers get wrong. Get the color, distance, hours, and intensity right and everything else gets easier. That is the whole guide.
Do I need to understand PPFD and DLI to use this?

No. The guide explains those numbers in plain language and gives you target tables, plus a free phone app method to measure light without buying a meter.

Will this help me choose which light to buy?

Yes. There is a chapter on panel vs bar vs bulb vs T5, how to judge coverage and PPFD instead of lumens, and what to skip.

Is this for hydroponics specifically?

It is written for indoor hydroponic growing, but the lighting principles apply to any indoor grow.

What format is it and how do I get it?
