I'm getting the off-season hydroponics set up, for 2020/2021

I got my two deepwater systems set up last week, and got the nutrients tweaked, and added some mycorrhizae and a small amount of mosquito dunk (to prevent fungus gnats). So last weekend I got some coir in the baskets I'd plant seeds in, and my cloner set up for things I start cuttings for, and hopefully, they'll root. Turns out, most rooted in 4 or 5 days, though some just starting. Surprisingly, the Thai basil rooted best, though this is still early. And no sign of roots on peppermint cuttings.

These have to get much larger, to transplant to the hydroponics.

Today I dug up a parsley plant - I rinsed the dirt off, then rinsed the plant with an H2O2 solution. Then I soaked the roots briefly in a rooting solution, then put it in the hydroponics.

I planted some seeds in the coir baskets; some greens that I always grow, like lettuce and mizuna, and some herbs - cilantro, Chinese parsley (leaf celery), and a couple I had old seeds for: hoja santa, and summer savory. Not even sure there would any viable in these last two, but I'd try. The mizuna is pretty old, too, but it was the first to germinate in 3 days! The youngest lettuce was up in 4 days, and the older one is just beginning to poke through.

Neat stuff. I would say reservoir temperature is the most important factor in root growth. They like it cool. And of course the more aeration, the better. You can use either air or water pumps for that.

What a fun thing to do in the off-season. I'm definitely going to enjoy watching you grow your stuff.

I use both an air pump, with an airstone in each tub, and a powerhead from one of my fish tanks, with a sponge filter attached. This way, if either the air pump or one of the powerhead dies (which can happen with those things, KOW), there is another form of aeration. The water pumps keep the tanks slightly warmer than the basement temp., and the plants seem to like that.

I got 5 of the clones set in the clay pellet baskets tonight - hopefully they will take. I put both Thai basils, and one each of the Gecofure and Serrata, plus one peppermint. Hopefully, I won't need the extras!

Here's that parsley, that was put in 3 days ago, showing growth in that center core, which was just barely started before.

Dill, chives, and the old lettuce seeds have come up, plus a couple of weeds! Plants on the edges, plus they weren't what I planted in the baskets.

That parsley isn't doing as well as it looked like it would, so I dug up the other plant - the larger one, which is why I took the other, as I figured I could get more of the roots of the smaller one. I tried to get more of these, and not cut off any of the tap root, and I definitely got more of these.

Here it is, getting it into the basket, and getting ready to put the clay pellets in, to hold it in place.

Here it is next to the smaller one, which is turning yellow. Only one you yellow leaf on the large plant - hopefully, the last!

Late last night, when I went down for one last check on the hydro, I discovered something that I couldn't believe actually sprouted - some Hoja Santa! It's a Mexican plant, which I grew a few years ago, and vacuum packed a bunch of it, to freeze, and I'm down to the last pack of it (it kept well all this time, vacuum sealed). I tried starting some seeds in spring, with no luck, and this was sort of a hail Mary - if this didn't work, I figured I'd have to order new seeds. These are the smallest seeds I have ever seen - like dust! I just sprinkled all of the seeds on the moist coir, and pressed them against it. And this sprout, that I noticed last night, after 8 or 9 days, was like an elongated white speck of dust - I used a 15x eye loupe to confirm that it was, indeed, a sprout. I don't recall how fast those things grow, but the plants eventually get very large (about 4' in diameter) - I'll have to transfer them to regular pots, but this is how I started them before growing outside a few years ago.

Hoja santa is in the same genus as black pepper (and many other plants) - Piper - and is often called "pepper leaf".
