Lettuce under LED lights, week two

Lettuces under normal light

The lettuces continue to put on mass.  The red colors in Yogoslavian Red (heading lettuce) are showing up nicely but it’s also the slowest growing.  And I cannot see a visible difference between Australian Yellow and Simpson Elite (with toothpicks). 

I split the soil cubes between two flats to give them more room and now I do a littly dosie doe with the flats every day to move the outside lettuces closer to the light. Fertilized again; I will drop back to once a month now, I think.

Just to recap, for people who stumble accross this post first:  Lettuces planted 10/23; sprouts show by 10/27; lights out and no heat 10/29-11/3; put under LED array on 11/8.  See Week One and It Begins for more history.

I ordered some “Red Sails” from Pinetree Seeds, an easier red leaf lettuce and I’ll start my next batch as soon as they arrive.  Hopefully, this weekend.
