The plan is to grow one nice little plant indoors. If it yields a few nice buds, I'm happy. If it yields more than 10 grams dry, I'm super happy.
My setup:
- 2,5 l (0,5 gal) plastic pot
- Coco-perlite mix (70/30)
- Generic fertilizer for vegetation and blooming
- EC meter
I put the seed directly into the pre-buffered coco coir and poured some tap water over it. Now I wait until it sprouts under its plastic dome.
Before someone mentions it: Yes, transparent pots are not optimal for root development. I just had this pot available and at least it will be interesting to watch the roots grow inside.
It sprouted!!
As soon as the first real leaves were there, I started giving nutes at around 500 uS/cm and pH of slightly below 6. I try to keep the soil moist but not wet.
DLI is around 14 mol/m² @ 14 h/day.
The leaves are rather small and wrinkly, but nothing to worry about (I hope).
Update on day 11:
I ramped up to 0,9 EC. The plant seems to take up the nutrients well. I water every day 1-2 times and try to target 5.8-5.9 pH.
My fear was that I water too much and stunt root development, but the tap root reached the bottom by like day 6 and some side roots are currently touching the side of the pot. Coco really gives gread aeration!
DLI has increased to 17 or so.
I am happy so far.
Topped above third node.
Some leaves are deformed, maybe the plant is disturbed by a second lamp next to its main lamp.
DLI raised to ~30, EC raised to 0.9. I find it strange that outflow EC is always lower than nutrient EC (0.7 vs 0.9).
For the next week I will further ramp up EC and start binding down side branches.
It's getting bushy and the first pistils are appearing.
The EC increased to 1.2 mS/cm and the plant seems to take it up. I find it a little worrying that the leaves are clawing and feel like crepe paper, but whatever.
Next week will be preflowering, so I will introduce bloom nutrients. Also, carefully tying down brances will be crucial to create an even canopy during the stretch.
The LST paid off, the canopy looks nice and even. I removed some bigger leaves that I could not tuck under the new growth.
Still no signs of buds :/ Maybe reducing the lighting schedule to 12/12 will help.
Finally, the plant is transitioning to flowering. It already smells like lemon balm.
I reduced the nutrient strength to 1.0 EC because some leaves have a dark green shade and claw.
The plant stands under a 100 W Viparspectra LED panel at a distance of around 25 cm.
I applied heavy defoliation this week and adjusted some side branches with garden wire. One branch snapped in the process :/
The smell gets stronger as the buds form.
I switched to 100% bloom nutrients and will up the dosage. Currently it's 1.2 EC input vs 0.9 EC runoff. It wants more, I guess.
