Having tried peat pellets and also peat pots, my experiences may be different than others. I noticed cucumbers with 4 to 6 true leaves growing in peat pots did not do as well when moved to an EarthBox. However, cucumbers with 1 to 2 true leaves growing in peat pellets did excellent when transplanted to an EarthBox. Those are two different experiences with more than one variable, and I am sure that peat pots are used successfully by many. The larger peat or coco pellets found in chain stores for starting tomatoes are what I am using this year, in conjunction with a Burpee Self Watering Eco Friendly seed starter.
Kathy, of the EarthBox company, staggers her plantings of cucumbers to extend the season. This is a good tip that I will experiment doing this year. Different cucumber varieties have different harvest periods, such as 2, 3, or 4 weeks, which makes succession planting a good choice. Mjb8743s experiences got me to try a 2/3 pattern planting of 5 pickling/fresh eating cucumbers to an EarthBox, which did wonderful for me for the high-producing, 4-6 vine, parthnocarpic variety that I grew last summer.
