Started germination two days ago, left in a glass until seeds sank then placed in a moist paper towel overnight. The seeds began germination quickly. I soaked some root riots in a very weak nutrient solution, rang them out and placed them with the seeds into a covered and heated propagation mat/pot thing. The humidity was at about 91% so I opened the airflow a tiny bit to get it between 80% and 90%.
18th Aug, plants showed tap root around an inch or less through the bottom of root riot, even though the humidity was high I was worried about them drying out or airpruning so young. I have now put all the seedlings into their final homes, the smartpot xl fabric. It's about 4 gallons I believe or something like 20l.
The mix is
Perlite 25%
Expanded clay balls 25%
Canna Pro plus 50%
After planting the seedings I waited for a couple of hours for some of the water to wick from the root riot to the pot so I could give a small watering in without over saturation.
I then added a 1 litre feed at less than 25% except for take root which I used at 50% strength. The 1 litre was split between 5 plants (one seed has started to open but seems to have stopped. I've kept her in the germination pot so she can keep having high humidity and warmth.) so they have all had around 200ml with a very weak feed.
I'm keeping the lights just over 30 inches away at the moment and will move slightly closer once their true leave emerge more. They popped out today on 2 seedlings and look very healthy, I will post some more images when they are a bit larger.
