The propagator is set at a temperature of 29 degrees Celsius (84.2 degrees Fahrenheit) at the soil surface level.
Approximately 6.5 cm (2.5 inches) of growth during this week

First of 3 shoots (out of 9 seeds) seen on Tuesday 28th of December 2010
This is a much lower % of success and I suspect the seed quality was not as good as the first batch. When the seeds are collected from the seed pods it is best to try and sow them within six months of collection. Old seeds will sometimes germinate but with less frequency.

Second set of seeds sown on Monday 20th December 2010
Approximately 5 cm (2 inches) of growth during this week
Sunday 12th December: Several more shoots are breaking through the soil. I am always amazed by the strength of these plants as the tiny shoots displace the heavy soil.

The grow lights are switched on to 8 hours a day (9 am -5 pm)
The grow lights are ‘plug and grow’ 200 w (6400k) white/blue spectrum. The white /blue spectrum is good for vegetative growth in the early weeks of the trees. Later, around week 10 /11 I plan to replace the white/blue lights with white/red equivalents. The white/red lights encourage flower growth. In the grow tent there are 4 of these lights hung from the ceiling of the tent.
Moringa Oleifera trees like a ‘little and often’ approach to water in these early stages. Each tree is given 2 fluid ounces (an egg cup full) of water twice a week.
The seeds are germinated in a large, heated, height-adjustable Vitopod propagator. The propagator has sensitive heat adjustments accurate to 1 degree. The propagator is situated inside a grow tent in my studio. Control of heat and light is both within the propagator and the grow tent.
Sunday December 5th: Each seed is geminated in a 13 cm (5 inch) diameter pots containing a mixed soil that is slightly acidic (pH 6.2). Each seed is placed about 1 inch into the soil and then covered over. The soil is fairly wet when the seeds are planted but no further watering is necessary until the seed breaks the surface of the soil. The soil is mixed with a mall amount of sand to help with drainage. Moringa Oleifera trees do not like wet soils around their root systems. Moringa Oleifera do need light in their germination.
The propagator was set at a temperature of 25 degrees Celsius (77 degrees Fahrenheit) at the soil surface level.
First shoots are seen on Saturday December 11th 2010
I have some archive posts to update about my miracle tree project at Nottingham Contemporary, starting in December 2010…
