On the 1st August 2019 I planted several spinach seeds in Jiffy 36mm Peat Pellets. Just after planting I discovered my new grow light arrived faulty, so my plans changed; rather than waste the seeds and peat pellets I started my Aerogarden Bounty; in that batch were three Lavewa Spinach and three Matador Spinach pods.
I also happened to start some San Moranzo Tomatoes. The tomatoes both sprouted three days ago, but so far not a single spinach sprout has emerged!
According to Botanical Interests (the seed supplier) both spinach varieties can take 5-10 day to emerge. So there is still hope. Fingers crossed.
Once replacement grow light arrives I will transplant any seedlings to the Kratky buckets, their final home.
I’d like to figure out how fast I can expect my plants to grow. Most seed packets and websites tell you how fast seeds grow assuming you are using soil, But hydroponics can grow up to 50% faster!
I doubt very much that my first hydroponic plants will grow 50% faster, however that doesn’t mean that I couldn’t expect to start harvesting from roughly that time onwards. You rarely need to wait until the plant reaches full maturity before you can harvest; just pull off leaves as needed and let the plant keep growing. I added “Potential Maturity” to the table below, but realistically that’s when I suspect I may be able to get my first harvest.
Earlier in the week I announced that we were hoping to grow the following vegetables and fruits in our Kratky hydroponic tubs:
I’d really to have some plants growing, or even harvestable, by late September/early October. Thats approximately 50-60 days from now. We have space for 2 large plants, along with at least 3 smaller plants and maximum of 5 plants.
The San Marzano Tomatoes are planned as a permanent setup, so these will take priority in one of the largest plant spaces. This tomato plant will be approximately 5-6 feet (1.5-1.8m) in height!
Whilst not quite as large as the tomatoes, the Lemon Cucumbers will stand about 3-4 feet (0.9-1.2m) in height. This will fill my second large grow area.
There are debates online about which spinach is “better”; matador apparently grows better in many conditions, but the Lavewa looks prettier and is slightly tastier. We want to test both of these spinaches side by side. They grow at the same rate, so we will test both the Lavewa Spinach and the Matador Spinach together.
I want to stagger the harvesting of my plants; I don’t want all my fresh leaf plants to mature at the same time, and then go one to two months with little food. So I have decided that I will start the Amaranth as well for this first hydroponic growth cycle. Granted, with its growth speed, I may be able to grow two batches of spinach by the time it reaches full maturity.
If I can fit anymore plants in my grow area I will add the Swiss Chard and the New Red Fire Lettuce.
What about you?
What are you growing this season? Did you calculate how long it takes to grow? Did you have to plan around seasons and temperature outdoors? Let me know what you’re growing!
After researching a bit, and probably jumping into the water too fast when it comes to buying products like grow lights, I have purchased some seeds to grow in my Krakty hydroponic room setup.
Buying seeds was a specific hassle in Kuwait; the very few and limited stores that sold seeds only sold very common varieties. Think Beefsteak tomatoes; the probably most common tomato you can find at any supermarket. Since such tomatoes are so easy to buy, I want to grow something more unique.
In fact, we even found a nursery selling seeds with the giant warning label on the back: “Warning. Treated with poison. Do not consume or grow food products from these.” What?!
