Hydroponics Tuesday

Discoveries and Research
1/22/2008 8:04:23 AM

Many things are pending and progressing this week.  Here is the first bit of news...

We've just published a review of the book How-To Hydroponics. In short, it's a great little book.  The information is relevant and current.  It's a short book, but a good one.

Secondly, an update on the new home-made aeroponics system:  As much as I hoped to announce it's completion this week, construction has been delayed.  The original model was going to be built from 4" square PVC.  However, after much consideration, I've decided to start over using larger 5" square PVC.  This should allow more room for irrigation and roots.  I think the larger diameter is worth the effort.

For those of you considering building your own "Aeroflo-style" units, here is a bit of preliminary advice:  Home Depot only seems to stock the smaller 4" stuff.  However, Lowes stocks both the small 4" and the larger 5" stuff.  We spent quite a while cutting and fitting the smaller stuff.  Now we're going to start over with the larger stuff.

Additionally, if you're building your own aeroponic unit...

  • Make sure to buy Botanicare's brand of 3" net pots.  They are much better for aeroponics than the more cheaply-made ones from General Hydroponics.  The ones made by Botanicare have a "solid ring" around the top, which will give you a much better water-seal around the pot.

I'm not sure yet what size pump will be required.  Truthfully, I've already got a PU250 from ActiveAqua sitting around, so I'm going to see how many aero sprayers it can power before becoming overwhelmed.  I don't expect that the PU250 will be enough pump for this project, but I'd love to know exactly how many sites it can power.

Also, in unrelated news...

I've been reseaching better varieties of strawberries to grow.  Please do not take this as anything but rabid speculation.  After doing a bit of reading, I'm looking forward to experimenting with Quinault variety strawberries.  Quinault is a fairly recently developed hybrid strawberry, which is said to produce large yields.  It's everbearing and self-pollinating.  Self-pollinating is becoming increasingly interesting to me, as we garden indoors extensively, and pollination via paintbrush is quite tedious.  We'll post results when we have some.  Expect it to be about a month, as we haven't even ordered any yet.

Jessa's exotics are doing very well in the MegaGarden.

We are continually trimming back the Bambino Eggplant.  We're getting about 10 little fruits each week.  This will probably be the last time that I run eggplant and strawberries in the same reserveoir.  I'd prefer to control the solution independently next time.

As always, here's the overview photo of the week:

PlantTypeStatus
#01Alexandria Alpine StrawberriesSmall fruit and flowers are appearing regularly.  Sadly, the runner that we attempted to root did not fare well.  It is in plant-heaven at the moment.
#02Alexandria Alpine StrawberriesSmall fruit and flowers are appearing regularly.
#03Alexandria Alpine StrawberriesSmall fruit and flowers are appearing regularly.  
#04Alexandria Alpine StrawberriesSmall fruit and flowers are appearing regularly. 
#05Alexandria Alpine StrawberriesSmall fruit and flowers are appearing regularly.
#06Alexandria Alpine StrawberriesSmall fruit and flowers are appearing regularly. 
#07Alexandria Alpine StrawberriesSmall fruit and flowers are appearing regularly. 
#08Alexandria Alpine StrawberriesSmall fruit and flowers are appearing regularly.
#09Alexandria Alpine StrawberriesThis fellow has had a hard life under the canopy of the eggplant. It's not strong, but it's surviving.
#12Bambino Baby EggplantThe Bambino continually dominates the TurboGarden.  Our constant trimming is all that gives the strawberries a chance.
#18Black Beauty Eggplant
Strong sproutling.  We'll probably move him in a week.  This one will likely get the "single-site" aero all to itself.
#19Black Beauty EggplantNot as large as it's brother, but quite healthy.  About 3" tall.  This one will eventually find a home in a WaterFarm drip system.  It's nowhere near old enough yet, so it will be staying-put in the MegaGarden for the time being.
#20Alexandria Alpine StrawberriesRecently emerged as seedling.  Happily living in the MegaGarden.  Still small, but that is to be expected with strawberries.
#21Alexandria Alpine StrawberriesRecently emerged as seedling.  Happily living in the MegaGarden.  Still small, but that is to be expected with strawberries.
#22Alexandria Alpine StrawberriesRecently emerged as seedling.  Happily living in the MegaGarden.  Still small, but that is to be expected with strawberries.

I had awesome success with Strawberry Picnic from Burpee Seeds. They stay compact in baskets or planters and have short runners, which means they are perfect for indoor hydroponics.

It's interesting that you mention those... I was interested, but couldn't find very much information about that breed. It appears that they are exclusive to Burpee. Do you know if they are self-pollinating?

I've gotten quite tired of manual pollination, and I'm trying to find a self-pollinating breed for my indoor growing. Thus far, Fort Laramie and Quinault are the favorites. I'm only able to obtain those varieties as plants, which means that I won't be getting them before March at the earliest.

A strong recirculating fan will make is so you don't have to worry about hand pollination if the plants are close together. They are great little plants, but the yield isn't as much as they could be. I am looking into Ozark Beauties, but they are only available as plants, not seeds, which makes me worry about pests.

Indeed, I have concerns about pests as well. I've ordered some Fort Laramie plants. I expect that they will arrive sometime in the early spring.

I have not yet fully planned out how to "clean" them before allowing them into the growing room. I'm actually considering taking individual cuttings for clones, so I can more closely monitor them.

We do run a ran in the growing room, but perhaps we should add an additional one near the strawberries. Regardless, I'm expecting that the new variety should produce larger fruit. The current Alexandria Alpine are tasty, but not especially large.

Hey Ben,

I gave you some link love to your blog on the front page at http://red-icculus.com

Much appreciated, Red.

I'll be adding a links section in the near future. I'll be sure to include you.
