Great for containers

5 out of 5 stars Jul 9, 2018
Love this plant and will be planting again next spring-summer. I'm in zone 9a and am currently growing two spacemasters inside a patio raised bed alongside marigolds. I followed the package instructions and starting these from seed in biodegradable pots in a mini greenhouse. They attract pollinators, love the heat and sun but do require a lot of water. Once they start to produce cucumbers they become prolific producers. I'm currently harvesting a cucumber almost every day to every other day.

Big Producer

Loved this lovely variety for my raised beds and kitchen garden close to the house. I grew them on a trellis and they have produced many tasty cucumbers. I pick them on the smaller side. Wonderful taste and easy to grow! Planting more for a second crop! Thank you!

Great results. I kept only a few plants, gave the rest to a farmer relative. I had so many cucumbers in a small space, that I will have to pickle them. Good taste, great product.

Love these!

4 out of 5 stars Aug 16, 2019
First time trying this variety and I really like them! The skins are thin and the cucumbers are crisp and snappy. Don't let these get too big though as they will get very seedy. I wish I could get enough at one picking to make pickles because these would make the BEST whole dills! These are my new favorite variety of cucumber and I'll grown them again with some adjusting!

Failed to germinate

2 out of 5 stars Sep 24, 2019
Tried same seed packet for to years, slow to germinate, only produced 1-3 cucs both years.
Linda Jacobsen from CO
Owner Response: Hi Linda, Thanks for your feedback. Is it possible that there were some pollination issues? We are hearing from more and more customers that don't have a lot of bees or just have European Honey Bees nearby that their flowers aren't being pollinated fully and that results in little to no fruit. If this is the case, plants can be hand-pollinated, we do have and article with a video in the "learn more" tab of this product. We are always here to help, please don't hesitate to contact customer.service@botanicalinterests.com.

A Surprisingly Forgiving, Robust Contender

5 out of 5 stars Jun 5, 2020
This cucumber has gone gangbusters. I got it from the Container Vegetable Collection set. I tried my hand at starting in a growing tray and transferring it. Mind you, this is the first time I'm growing vegetables and... I went ahead against the advice on the packet. I was alarmed when some roots ripped and thought I'd blown it. I put it in a self-watering container with compost, Down to Earth Seed Starter and Bio-Live fertilizers (with mycorrhizal fungi for root support), and made sure to keep the water reservoir as full as possible. It's neighbors are a squash and an Oregon sugar pod pea. It took off and has gone gangbusters, even faster than a bush bean sown at the same time. It lives up to its odd industrial, sci-fi name and is doing well in a container. Haven't harvested yet but it's been a pleasure to grow.

Cucumber Spacemaster 80

Amazing seeds, I ordered these and planted a few seeds in groups of 2. I planted them after the 4th of July and they are sprouting. I wasnt sure if these would even come up as I have a corner of the yard that is so so. I added a couple bags of home depot raised bed mix to amend the soil and they are looking better than the cucumber transplants already :)

These cucumbers were extremely slow to grow, and were plagued with problems. Despite a thriving garden, these plants never met their benchmarks. I felt like I was constantly looking up information for a new problem. I fought powdery mildew all summer, unsuccessfully. I have not had this level of issue with cucumbers in the past, and will likely not plant these again next year. It was the only thing in my garden I wasn't absolutely thrilled with.

Owner Response: Hi Kate, We are sorry that you didn't enjoy these 'Spacemaster' cucumbers. We have some tips for combatting powdery mildew online, and the key is to treat plants before there is an issue, because once you have it you cannot rid your plants of it. I am not sure if this was also an issue but we frequently hear about issues related to pollination (fruit drops off or no fruit forms) and in the 'Learn More" tab of this product page you can find instructions to diagnose this issue and to pollinate you cucumbers by hand. We are always here to help. A customer service agent will contact you about these issues.

The cucumbers were tasty, but shaped like a blimp and had very sharp spines, with huge, tough, seeds. The more solid parts of the cucumbers were delicious.
Deborah from CO
Owner Response: Hi Deborah, From your description sounds like these cucumbers should have been harvested smaller. As cucumber fruit gets larger it fills with seeds and the seeds get tougher as they mature. We hope that helps. Happy gardening!

great performance at 6800 feet elevation, in a container, I have to container garden for everything to protect from voracious rabbits. I use lick tubs lined with ridged foam insulation to protect roots from heat

Tasty cukes from healthy, productive plants

5 out of 5 stars Jan 17, 2021
I had a great yield of tasty cukes from four plants. The plants are bigger than the description sounds, at least in my central IL raised beds. Will definitely grow these again.

Productive and tasty, but not resistant

4 out of 5 stars Jul 16, 2021
Very productive and tasty, but unfortunately not very resistant to mosaic virus.
Diana from NC
Owner Response: Hi Diane, We are sorry you experienced a disease in your cucumbers. This variety is resistant to mosiac virus, but with any resistance, it will resist, but it doesn't mean it is 100% protected. We sure hope your garden is productive. Happy gardening!

Loved them, however....

This was my first time growing cukes and I did it in an AeroGarden! I watched as it went from seed to beautiful vined plant. Grew extremely well until fruiting and because I had not placed them on a trellises it fruited two beautiful cukes and died off shortly after. I will try again with a few trellises this summer. Report back later. Loved these seeds!

To many male blossoms

3 out of 5 stars Jul 1, 2022
I'm growing these in a greenhouse using hydroponics. Hard to hand pollinate because of mostly male blossoms and when females come, the males have shriveled up. Also they are about six feet tall.
Gary from WI
Owner Response: Hi Gary, Thank you for letting us know about your experience. Ensuring proper nutrients is important for the development of female flowers. Female flowers are usually limited when the plant is looking for resources. Cucumbers need moderate nitrogen and high phosphorus and potassium. A hydroponic EC meter will read how strong your nutrient solution is. I hope this was helpful! Feel free to reach out to our horticulturist with questions like this, we are happy to help!

Amazing little cukes!

5 out of 5 stars Aug 17, 2022
I was drawn to this variety by the sci-fi sounding name and the knowledge that it's good for smaller spaces. This variety has truly impressed me. It's incredibly prolific, a heavy producer and quick grower. Between the 8 or so plants I have growing, I'm currently harvesting at least 5-7 cucumbers per week and there are many more to come. I highly recommend picking them when they are about 4-6" long as they are much sweeter, and have little to no seeds. Any bigger and they become spongey, bitter, and seedy. I am growing my cucumbers vertically for the first time this year in my tiny urban backyard and this variety is perfect for this.

Overall a Great Choice!

5 out of 5 stars Mar 11, 2023
I grew these last season as my very first year gardening. I grew them in 5 gallon grow bags and trellised them. They did amazing and I got plenty of cucumbers. However, a couple of my plants did get powdery mildew. Package says they're resistant, so maybe keep that in mind. It's also very humid/rainy in Atlanta so it may be unavoidable in some climates.
