Thank you. A range of numbers is what I was looking for. And "couple of weeks" is a clue. Does no one have photos of this stage? The Maestro has said and I believe him, that he can do the 420Scrog with any auto cultivar. Results vary of course. I see that in my own plants, two seeds from the same pack can produce different shaped plants raised under identical conditions and rotating positions under the light. I keep track daily with good meters of pH, ppf, EC, and DLI. Waiting for two new Migro lights to arrive for the "lab."
If you're interested in every known way of maximizing nodes and minimizing internode distances in those first three weeks, ask ChatGPT4o. You'll be surprised at the wealth of specifics, pages worth.
