    My first time with Lettuce...What now?

    dniezby

      @It looks like EVERY seed of Buttercrunch I planted in my Rockwool has germinated. Same thing with my Four Seasons Lettuce. This is 7 days worth of growth. I've had it under an LED Red/Blue panel for 14hrs daily.joed

       

      Should I do anything with these now?

      Any input would be greatly appreciated.

          Hi dniezby,

           

          1. Lose the "red" spectrum of light (if possible). The red spectrum promotes the reproductive growth stage of plants (a.k.a. flowering / fruiting) - not something desirable when growing vegetative growth stage plants (leafy greens and/or herbs).
          2. With head-type lettuce, thin-out the seedlings so that only the healthiest one remains (a pair of tweezers helps with this).

              If I’m right, each one of these is in the stage where it only has two leaves...right? Any of those will grow out to the actual plant that I will eventually harvest?


              So, now I should just pick the healthiest and remove the rest to leave one plant or leave a few and remove more of the plants as it grows choosing the healthy?


              Won’t removing the plants still leave the root in the rockwool and if so, won’t the plant just return? 


              Sorry a lot of questions.

                  Hi dniezby,

                   

                  "If I’m right, each one of these is in the stage where it only has two leaves...right?"

                  At this point, your plants are in the "sprout" stage. The embryonic first leaves are called "cotyledon" (they are not actually true leaves). Plant species with two cotyledon are called "dicots". Plant species with one cotyledon are called "monocots".

                   

                  "So, now I should just pick the healthiest and remove the rest to leave one plant or leave a few and remove more of the plants as it grows choosing the healthy?"

                  For non-bunching / non-clustering / single stem type plants (like head lettuce), thin-out all but a single sprout (a pair of tweezers helps with this). Carefully & slowly remove sprouts by pulling up on them to remove the sprout, root & all. The longer you wait to thin-out, the more established the roots will become... making it more difficult to remove the sprout.

                   

                  "Won’t removing the plants still leave the root in the rockwool and if so, won’t the plant just return?"

                  Generally, this will not occur if you thin-out during the sprout stage (before the true leaves appear); this is because the plant is still in an embryonic development stage. Thining-out during this early stage of development usually allows you to remove the entire sprout - root and all.

                      AWESOME info. Great stuff to learn. I’m out today, but now I definitely will be cleaning out the sprouts. 


                      This is something that should be done for EVERY plant right? I mean, I have Cilantro, Swiss Chard, and Roma tomatoes all have multiple sprouts. 


                      I do have two plants that confuse me in this stage though. I will start a new thread for that so your answer will be easier for people to later search for.
