Distance from the light – so important
July 17, 2007
Distance your plants are from the light is critical.
With sodium bulbs, they can stress your plants very easily.
Start with fluorescent about 40″ from your cuttings or seedlings.
Once your plants are about 12″ high, they can take the strength of a 250W light.
However, NOT directly shinining onto them.
Instead position your light in the centre, and move your baby plants to the far corner. Distance from bulb to floor should be 4 feet.
Once they have grown to around 18-24″ and are looking thick in the stems, you can then move underneath the light. Still make sure there is 3 feet of distance. If the plants stretch you know they need to go closer to the light.
If you don’t follow these rules, you stunt your plant growth with stress and it shows up later down the line.
