Coverage & Planting Details
| Coverage | This packet sows up to 23 feet of trellised cucumbers. |
|---|---|
| Row Spacing | 36" |
| Seed Depth | ½" |
| Seed Spacing | A group of 2 seeds every 12" |
| Thinning | When 3 leaves, thin to 1 plant every 12" |
| Germination | 5–10 days |
| Start Indoors | 2 to 4 weeks before your average last frost date. Cucumbers are sensitive to root disturbance; sow in biodegradable pots. |
| Direct Sow | RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is at least 60°F, ideally 70°–90°F. |
| Growing & Harvesting | Pick, and pick some more! Overly mature cucumbers on the vine will slow production of new cucumbers. Cut the stem rather than pulling at the fruit, as stems are fragile. To increase the quality and storage time, once picked, immediately immerse in cold water to disperse "field heat". |

- Vickie R.Verified BuyerRated 5 out of 5 stars5/14/26Great Germination Rate
This cucumber had a very decent germinate rate. I started some inside and some on heat a mat. Both worked well, but I think they germinated a little faster being sowed outside in my Greenstalk, using seed houses. They're all outside now and growing without issue. Hopefully, our FL humidity won't take them out before I get a harvest. Overall, very pleased.

We love hearing about your great germination success with our Spacemaster 80 Cucumber Seeds! It's awesome that both your indoor and heat mat methods worked well, and how cool that the ones in your Greenstalk with seed houses germinated even faster. Your FL humidity concerns are totally understandable, but it sounds like you've got everything set up perfectly for a fantastic cucumber harvest! Thanks for sharing your detailed growing experience with us! Keep on growing 🌻️
- Marilyn P.Verified BuyerRated 2 out of 5 stars4/15/26Easy to germinate. Very prone to rot
Rotted early even with soilless media. Zero “keepers out of first sowing.
Which best describes you as a gardener? IntermediateBIBotanical Interests4/19/26Hey Marilyn,
We're so sorry to hear about the rot issues you experienced with your Spacemaster 80 Cucumber Seeds! That's definitely frustrating, especially when the germination went so well initially. Cucumber seedlings can be tricky with moisture levels - they love humidity for germination but can be sensitive to too much moisture around the stems once they're up. Even with soilless media, sometimes air circulation and watering technique can make all the difference. We really appreciate you sharing your experience as it helps other gardeners know what to watch for. We hope your next sowing gives you much better results! Keep on growing 🌻️
- YvonneRated 2 out of 5 stars2/1/26Bitter in hot climate
This is the only seed packet I did not like from BI. If you are living in a hot area where in summer time it’s always above 90 degrees, this is not a cucumber for you. It was really bitter even though I water the plants twice a day. I do recommend the tasty green cucumber. That one is a heat resistant variety.

Thank you so much for sharing your honest experience with the Spacemaster 80! Your feedback about growing conditions in extreme heat is incredibly valuable for other gardeners who might be dealing with similar high-temperature challenges.
We really appreciate you taking the time to recommend the Tasty Green variety as a better heat-resistant option - that kind of variety comparison from an experienced gardener is going to be so helpful for other customers in hot climates who are trying to decide which cucumber seeds will work best for their growing conditions.
Your real-world growing experience in those 90+ degree conditions gives other gardeners valuable insight into variety selection based on their local climate!
Keep on growing 🌻️
