Here is a picture of the current batch of several Dwarf Lavender varieties grown from seeds in my SG9. With the exception of one pod, the rest are growing vigorously and budding. This is at week 5. I am supplementing light with two LED lamps. I will transplant them in a week or two.
Where I am in Singapore, we have hot and humid climate which is poor for many plants available as click and grow pods. Hence lavender remains a challenge to grow and thrive in Singapore.
The lavender seeds are purchased from various sources based on their dwarf characteristics. I cold treat them in the refrigerator and germinate them in a lock&lock lunch box in the refrigerator. They remain viable for many months until they are ready for the SG9. The germinated seedlings once put into the SG9 will grow robustly within a week usually.
I have had some limited success in sustaining them when transplanted into pots but many are struggling to thrive. Currently I am trying to dial in the best conditions required for them to thrive locally. I am experimenting with the optimal amount of water and also the medium required for best growth.
