How do you all get explosive seedling growth?

Hello.

I gave/give them as much light they can handle, and under 24/7 of lightning.
They grow more explosive/faster in coco/semi-hydro then in soil, so choose the best medium for maximum growth.

Give the correct EC of nutrients also helps.
And some seedlings are faster then others, if you pick those early its easy to grow a monster-plant.

I will show you exactly what im looking at when i pick a winner and how i do.
Cant say my way is the best but its a way to do it.

Nobody so far has mentioned VPD. Make sure your environment is humid enough to encourage rapid root growth! Most overlooked variable IMO and I've stunted seedlings in too-dry tents before.

Agree. Something like a moisture dome or humidifier to keep the humidity up for young plants

Feeding 3x a day or more in coir does the trick.
