Flowering days separate

Growers plant seeds from the same strain same batch at the same day and plants still develop at different rates. Grow them together. Later (depending on a result) either harvest together or partially as some growers do.

Breeder estimates are educated guesses at best. Your "fast" one might take longer and the "slower" one could finish early. Even when growing the same strain things don't always finish the same, especially when multiple phenos are involved. If you gotta chop em all at the same time you just have to base it one when most of it is ready.

don't dry in your tent, anyway. It's too small of a space unless you live in an arid climate, then it might be an advantage.

Was willst du denn genau wissen? Wenn es darum geht das eine früher fertig ist und getrocknet werden soll, nimm halt nen großen Karton mach ein Loch rein hau Schlauch drauf und verbinde mit dem Zelt. Belüfte den Karton und achte auf Temp und Luftfeuchtigkeit. Auch wenn das natürlich nicht leicht ist, da das Zelt natürlich andere Werte hat wie du zum trocknen brauchst. Aber was willst du sonst machen.
