Microgreen Test Dec 15

Dec 15
We are up at the farm in Oregon, and it is cold out. The logical place to grow the microgreens now is in the garage as there is no place indoors where we can keep it heated.

So my first worry was too be able to keep them at about 70 degrees so they can germinate. John came up with the idea of using a space heater on low. I ordered some Vivosun heating mats also.

Broccoli Micro’s on day 9 , the best performer

My new set up in the garage on the farm in Beaverton.
Using the new LED T5
This fits a 10 by 20 tray or 2 of the foil pans I use

Vivosun 2 pack 10 by 20 Heating Mat

I also am using coconut coire either for the whole substrate or mixed half and half with potting soil .

Microgreen set up
Rustic set up to get started. I only have a few weeks to complete this grow

Above are the trays that I weighed down for 3 days, then I flipped the tray to keep them in the dark.

Slowbolt Arugula
Waltham Broccoli
Red Acre Cabbage
Speckled Pea

Along with the microgreen shots, I am experimenting with salad cups.

I had some concerns up here in Oregon that I didn’t in Palm Springs.
I am worried about the temperature and the humidity as well.

So I used the coconut coire to lightly cover the seeds. I learned that from Pepe a microgreen grower that feels it is a very neutral substance that will keep the seeds protected. So he puts a light coating over the top of the seeds.

Arugula day 3 nice germination

Dec 18 day 4

Arugula ready to uncover

day 4
Amaranth on Day 4, after 3 days of weighing down, they are peeking through.
I used some coconut coire to cover the seeds so they had to sprout farther through
this covering. I am not sure I will use this much again.

Arugula day 5
Arugula day 5
I uncovered them this morning.

Broccoli day 5
The Broccoli day 5 has never been uncovered but it is still gaining color. It must be creeping through. I should maybe cover these with towels.
Amaranth day 5
Amaranth day 5 still covered
Microgreen Shots
Microgreen shots day 5, some with paper towel on a bed of coconut coire and also
some with just coconut coire . The broccoli on the paper towels are doing well.
The arugula is gaining lots of growth and the Amaranth is peeking through.

Day 5 the salad cups have greens peaking through. I put quite a bit of coire to cover them. I watched one Microgreen grower that fills them up to the top with the soil mix so that you can weigh down the seeds.

The blue is pea shoots that I only had a few seeds left.

Red Acre Cabbage day 5

Day 7

Towel set up
I started covering the trays yesterday with towels to keep light from creeping in the cracks of the blackout domes. I noticed that several trays were greening up even though they were covered. I noticed that the towels also kept the trays warmer and the growth accelerated.

Broccoli gaining nice height, overtaking Arugula in size

Broccoli and Arugula
Broccoli and Arugula day 7
The Basil has finally gotten a little growth going.

Red Acre Cabbage
The Red Acre Cabbage gaining nice height.. Should be able to uncover this soon.

The Beets have finally gotten a little height to them.

The Sunflower has finally gotten a few looking up with a leaves. Seems like it is much slower than usual.

Amaranth gaining some nice height. some were tangled up in too much coconut coir. Seemed wet so I am thinking of uncovering this soon to avoid any mold.

Microgreen Shots
Surprisingly the microgreen shots have gotten height fairly fast. The coir underneath the paper towel has definitely kept t he paper towel moist.

Microgreen Salad Cups
Last and the least the salad cups are gaining in height a bit but so much coir is on the salad ones and the pea shoots barely showing a little height. Slower this time than even the basil.

What a disappointment this has been to see the beets and the amaranth dying.

It looks to me like either too much water or a fungus that eventually rots the stem. Sometimes referred to as damping off, it is a fungus that eventually rots the seedlings. They looked as if they were doing fine then they are starting to collapse and fall over, or just wither. The beets are falling faster. Not a good Christmas present but I should expect some. Also the seeds may be too crowded.

I immediately took the towels off the new crop fearing that I am creating too damp and warm an environment for the fungus to grow. It is not getting any ventilation either. I shot them with a bit of hydrogen peroxide.

On the other hand the Red Acre Cabbage is doing well, so is the broccoli and Arugula

Amaranth on Christmas looks good
3 Days later it is starting to die. So frustrating. It could be I am using too many seeds or damping off. Amaranth has just been tricky up here in the grow area. I have ordered a dehumidifier. I am going to sanitize my growing trays much better also.

The Arugula looked as if it was dying off but I found it just needed water. It bounced right back, as did the red cabbage and a few other things.

The little food containers I have had some success. The ones with strictly radish worked well, the combo radish/ broccoli didn’t seem to go well. There was some damping off.

The Basil after 14 days seems is just barely hitting the top of the tray height. Very slow growing.
