A rooted cutting spends several days sealed in the dark, upside-down in a truck, and arrives alive. Here is the biology and the packing that make that ordinary.
Plants do not need light continuously; they need it on average. A clone in a dark box goes into a low-metabolism holding pattern, spending stored sugars slowly and losing very little water because the sealed environment stays humid. Nurseries lean on this deliberately: a well-watered cutting in secured medium has everything it needs for a multi-day ride.
What it burns through is reserves, not health. That is why an arriving clone looks tired rather than damaged, and why the first day out of the box matters more than the whole transit did.
Temperature, overwhelmingly. Heat is the real killer: a box left on a summer porch turns into an oven within an hour, and no packing survives that. Freezing does the same job in reverse, faster. Everything else that worries buyers, jostling, being upside down, a few days of dark, is survivable by design.
This is why arrival-day attention beats every other precaution. Route deliveries somewhere shaded, or hold at the carrier's facility, and unbox the day it lands.
Droop, pale color, a curled leaf or two, sometimes a yellow lower leaf: this is normal transit fatigue and it reverses within a day or two. The plant spent its stored energy and drank whatever was in the medium, and it is thirsty and stiff, like anyone stepping off a long flight.
Look at the growing tip rather than the old leaves. If the newest growth is firm and green, the plant is fine. Genuine damage looks different: crushed stems, snapped branches, or a root ball that arrives dry and shrunken.
Photograph the box before you unpack it, then unpack immediately, water lightly if the medium is dry, and set the plant under gentle light. Do not transplant, do not feed, and do not put it under full-power light or direct sun on day one. Give it a day to remember it is a plant.
Once it perks up, the hardening and transplant schedule begins. Every listing on the marijuana clones shipped manifest arrives on the same terms, so the routine is identical whichever cut you ordered.
