Your clone shows up rooted, healthy, and ready to work. What happens
next is on you, and the first two weeks decide most of it. This guide
walks you from the box on your doorstep to the day you chop, written for
growers running their first clone. I’ve walked hundreds of first-timers
through this exact sequence by phone, and the ones who follow it almost
never lose a plant.
If you haven’t picked a strain yet, browse the full catalog first. Everything below applies to
any cut we ship.
Inside the box you’ll find your clone secured upright in its rooting
medium, moist and shipped in discreet packaging. It’s freshly rooted,
which means the roots are alive and established in the plug, not just
callused hopes. Open the box the day it arrives. Every hour it sits
sealed is stress you didn’t need to add.
Do not transplant on day one. Your clone just spent time in a dark
box, and going straight from that into full-blast light and a new pot is
how beginners cook a healthy plant. Here’s the acclimation routine I
give everyone:
Questions about transit time or what condition to expect on arrival
are covered on the shipping FAQs page,
along with how the Live-Arrival Guarantee works.
After 24 to 48 hours of acclimating, your clone is ready for its
first real home. Start small. A 1-gallon pot is plenty, and you can move
up to a 3, 5, or 7-gallon later. Small pots let you control moisture,
and moisture control is the whole game early on.
The transplant itself is simple. Fill your pot with a quality light
potting mix, make a hole the size of the root plug, set the plug in so
the top sits level with the soil surface, and press the mix gently
around it. Water lightly around the base, not a flood, and put the plant
back under gentle light for a day before ramping up intensity.
Handle the plug, not the stem. In 16 years of working with genetics
I’ve seen more clones lost to rough transplant handling than to any pest
or disease. The roots coming out of that plug are fine as hair. Crush
them and the plant spends a week rebuilding instead of growing.
Cannabis in veg wants 18 hours of light and 6 hours of dark. That
18/6 schedule keeps the plant in vegetative growth, building stems,
fans, and roots instead of flowers. Set a timer and forget it.
Inconsistent light schedules confuse the plant and stall growth.
Intensity matters as much as duration for a young clone. Start your
light dimmed or raised higher than the manufacturer’s chart suggests,
then bring it down over the first week as the plant shows it can handle
more. Leaves reaching upward and praying is a good sign. Leaves tacoing,
bleaching, or curling down means back off.
Here’s the thing beginners miss: your clone arrives rooted, not
established. Those roots can take up water and light nutrition, but they
are not the mature root system of a plant that’s been in a pot for a
month. Feed it like the young plant it is.
For the first week or two after transplant, plain water or a
quarter-strength veg nutrient is all it needs. Most quality potting
mixes carry enough nutrition to run a young plant for a couple weeks on
their own. Work up to half strength, then full strength, over three to
four weeks, and only increase when the plant shows healthy new growth at
the current dose. Slight nutrient hunger is fixed in days. Nutrient burn
costs you leaves you don’t get back.
Overwatering. The number one clone killer, full
stop. Roots need oxygen, and a permanently soggy pot suffocates them.
Water when the top inch of medium is dry and the pot feels light when
you lift it. Then let it dry down again. Wet-dry cycling builds
roots.
Transplant shock. Caused by rough handling,
transplanting too early, or blasting a fresh transplant with full light
and full nutrients on the same day. Change one variable at a time and
give the plant a day or two to respond before you change the next.
Light stress. More light is not automatically more
growth. A clone that spent its first weeks under propagation lighting
needs a ramp, not a wall of photons. Bleached tops and clawing leaves
are the plant telling you to raise the light or dim it.
When your plant has filled out its pot and roughly half your
available height, flip the light schedule to 12 hours on, 12 hours off.
That 12/12 schedule triggers flowering in photoperiod plants, which is
what every clone in our catalog is. Expect the plant to stretch for the
first two to three weeks after the flip, sometimes doubling in height,
so flip earlier than feels natural if your space is tight.
From there, flowering time depends on the strain, and that’s listed
on each product page. Keep the dark period truly dark, keep feeding
consistent, and resist the urge to chop early. The last two weeks put on
more weight and ripeness than beginners expect.
Some cuts punish mistakes harder than others. From our catalog, Super Lemon
Haze and Gorilla Glue #4
are widely considered forgiving picks that bounce back from beginner
errors better than most. No strain is idiot-proof, but these two give
you margin. If you’re drawn to a stretchy sativa like AJ Sour Diesel,
just know it wants headroom and a grower who’s comfortable training, so
read the strain page before committing. Compare everything side by side
on the all strains page.
Ask early. A yellowing leaf on day 3 is a five-minute conversation.
The same problem ignored for two weeks is a rescue mission. Call us at
844-697-3337 if something looks off with a clone we shipped you, take
clear photos in natural light before you call, and don’t dump a cocktail
of fixes on the plant before you know what’s wrong. One problem, one
correction, then observe.
Give it 24 to 48 hours after unboxing. Your clone traveled in the
dark, and it needs a day under gentle light with stable temperature and
humidity to rehydrate before its roots get disturbed. Transplanting the
moment it arrives is one of the most common causes of early
stalling.
Run 18 hours of light and 6 hours of dark. That 18/6 schedule keeps
the plant in vegetative growth. Start with reduced intensity for the
first week after arrival and increase gradually as the plant shows
healthy new growth.
Hold off for the first week or two after transplant. A freshly rooted
clone is not an established plant, and most quality potting mixes carry
enough nutrition for the early stretch. Start at quarter strength, then
work up to full strength over three to four weeks as the plant
responds.
Flip to a 12/12 light schedule when the plant has filled out its pot
and reached about half your available height. Plants stretch hard for
the first two to three weeks after the flip, so flip earlier if your
vertical space is limited. Flowering time from there depends on the
strain, listed on each product page.
