Propagation Plug Comparison Part 3: How did the lettuce seeds fare?

Much like the variance we saw in the amount of root development on our tomato and basil cuttings, there was a huge variance in lettuce growth between the different plug types. Two weeks after seeding, the winners (and losers) were clear.

The top performing peat plug in the cutting comparison stood out on the lettuce growth test too. This plug had the most leafy growth with 4 fully emerged true leaves. Floral foam and two other peat plugs also did well with 3 good sized true leaves and the 4th emerging.

Bringing up the rear, both rockwool plug types had two small true leaves. The seeds planted in the h**p fiber plug had no germination for over a week and of the plugs that did germinate, only the seed leaves (cotyledons) were visible at the end of our two week test.

We seeded 6 plugs from each plug type and had 100% germination in all but one of the peat plug types and 100% in the floral foam plugs too. Both the rockwool and h**p fiber plugs only saw germination in 4/6 plugs.

So, what plug did we select as the overall winner? Head over to our shop (www.geckogrow.ca/shop) or stay tuned for the the reveal in an upcoming post.

Happy Growing! 🇨🇦🌱🦎
