Wow your SpaceMaster plants are doing great. I planted mine in November under indoor Grow lights. They are just now starting to fruit.
a. What sort of soil and container size are you using?
b. What sort of light do these plants receive? How many hours of light do they get/day?
c. What sort of fertilizer and how often?
Thank you so much in advance.
Thanks, Vrkelley! Yes it was doing great, until I sort of overwatered and it got a bad case of powdery mildew. It is still producing though, strangely. Wow, I didn’t know you could grow cucumbers under Grow lights. That’s cool.
a. I use a soil-less organic potting mix and a 9-inch container. The container is actually pretty small, and most of the cucumbers grow to as long as the container is tall. The plant doesn’t seem to mind though. The only hassle is the container dries out pretty fast, and I’ve to water 2-3 times a day, depending on how hot it gets. It’s pretty obvious when the plant needs watering, as the leaves become limp and wilty. They perk up again a few minutes after watering though.
The plants receive full direct sunlight from about 11 am – 6 pm. We do get intense afternoon sunlight and heat here, being in the tropical region, which I think is most responsible for the plant growing so big so quickly.
c. I used some organic fertilizer to encourage flowering initially, as I wanted to keep the nitrogen level low and encourage the plant to be fruitful, so to speak. I’ve run out of that though, so now I only use organic chicken manure that I get from our local nursery. But I think more important than the fertilizer is the quality of the potting mix / soil, to make sure there’s lots of nutrients and organic matter in there already.
So the other thing I would encourage you to do is not to overwater and try to protect your plant from powdery mildew somehow, as once it gets that then it’s almost like plant cancer, very hard to get rid of and keeps recurring. It will slow down the fruit production significantly, and damage the gorgeous leaves on the plant.
Anyway, I hope you get to enjoy the fruits of your labour soon!! :):) I enjoyed mine in a salad and my brother cleaned up the bowl!! :):)
Thank you for your response. Glad your family is enjoying salad. I have 3 SpaceMaster 80 in a 14 inch wide X 14" deep container. These three have probably 75-100 male blossoms and about 3 females.
The 4th plant is sitting under a less intense light and looks more like your lovely plants. Neither container is producing. So it looks like it’s time to try your Q-tip method! Next time I’ll try a different potting mix.
Also, which brand of Spacemaster seeds are growing in your container?
That looks great, i am going to be trying to grow some cukes for the first time in pots this year rather then in the garden and its nice to see that you’ve had great success with it.
Thanks for sharing.
Reporting back on the hand pollination. Your Q-tip idea works well. 2 cucumber fruits are growing, growing, growing! Sweet!
Rockabella9 how many SpaceMaster plants do you have growing in a single container? For your growing conditions, how many cucumber plants must grow to feed a family?
Vrkelley, wow, that’s a lot of blossoms. I have limited space, so I pinched the growing tip when it got to about a metre tall, and it stopped growing vertically immediately. Glad to hear your plants are fruiting well. I’m sure you will be able to eat them by the end of the week or so. My Spacemaster seeds are from Mr. Fothergill’s. Their seeds are very reliable and germinate almost 100% of the time. I had only 1 Spacemaster plant growing in a container. I didn’t know how many to plant, but I’m glad I kept to 1 only, as it’s a huge plant. A single leaf had about the same surface area as the top of the container. I think you should have enough plants to feed cucumbers to your family, unless you eat unusually many cucumbers or your family’s really large. Each plant should yield an 8-inch or so cucumber per week. My plant usually had 1 growing fruit on it at a time. Even though there were other pollinated female flowers on it, these baby fruits don’t grow until the big one is harvested. Not sure whether this is due to the small size of the pot or what though…
Thanks Penny! Good luck with your cuke plantings! I thought it would be hard to grow veggies in smallish pots, but apparently some plants are very suitable for pots and tubs. I think Nax from this site as well commented that it could be that they concentrate more energy on developing leaves and fruits instead of extending their roots. The only problem with growing in pots I found is that they do dry out quite fast on a hot day if the pots are small. I couldn’t give them all the water they need in a day at one go as the pot can’t hold so much and the water will leak out from the drainage holes. So I’ve no choice but to water again later in the day, which can be quite a chore :(
Reporting back after two weeks! The 4th plant is sitting under a less intense light has two cucumbers that are about 2 inches long. More female also.
Rockabella9, I wonder if your cukes are growing quicker because you clipped the top of the plant (in addition to your really great intense light). You may be able to add a self watering container on top of the soil by cutting off the bottom a 16oz water bottle and sticking the neck in the soil. Then fill the bottle from the top.
What brand of fertilizer and soiless mix are you using? I’m using 1/2 Perlite and 1/2 Miracle Grow potting mix.
