Welcome back to another episode of Lost In The Farmer’s
Market, and this week we have the results of the big product trial. Bur before we look into that here is the
photo of the week.

| Peucetia viridans
– Green Lynx Spider |
I happened to see this one on the flowers of the red Globe
Amaranth just the other day. For note this is a mature female green lynx spider
and typically they’ll hang out near flowers to catch pollenating insects or in
this case she’s caught a Cicada Killer Wasp. It’s rare I have the camera near
when I spot these spiders and so this picture of one was worth posting. Now
before any of you freak out this spider isn’t venomous or aggressive towards
humans and is rarely found inside unless it came in on a plant. These spiders
perform some beneficial tasks as they become rather voracious just about when
paper wasps become aggressive in general and as you can see a wasp for them is
no challenge. This also means moths are at risk for becoming lunch too so fewer
chances for horn worms or cabbage moth caterpillars. But enough of that, onward
to the trials.
As some of you know every year LITFM performs a long-term
trial of a given horticultural product to determine if the product’s claims are
valid. Often in the process we end up learning a few new things about the
subtle interplay of environmental and biological factors versus a given
product’s usefulness. The Smart Pot trial was actually suggested by the folks
at Flow & Grow in town and we figured that it was as good as any idea to
test because the product unlike the normal things we tested didn’t make
incredible claims instead what was suggested by the packaging was reasonable
and scientifically plausible. We also
took the suggestion posed over at Flow & Grow to offset the pots because
apparently the Smart Pot #7 pot despite being larger than a 3-gallon nursery
pot was equivalent. I think the idea of offsetting may have been in the sales
information provided by the company as a means of making the watering needs of the
#7 equal to that of the 3-gallon pot. But anyway below you will find the
photographic evidence of the trial and the particulars of how it was done and
at the end is a summary and from this trial you can draw your own conclusion.
Product &
Materials Trial: #018
Concept:
A fiber-based growing container under the brand name Smart
Pot claims on their packaging to encourage superior root formation because the
fibrous walls of the pots allow superior airflow. As a result of this airflow
yields are said to be greater with overall bigger plants. Additionally these
pot due to their porous nature are said to have enhanced capillary action of
moisture between the soil in the pot and the moisture in the ground if placed
in contact with the ground.
The Trial:
A single #7 smart pot will be compared against an equivalent
standard plastic nursery pot of the same color so that thermal efficiency is
not an issue. The two plants will be placed with a facing so that each receives
no less than eight hours of full sun and will receive identical fertilizer
treatments.
The Plant Stock:
The plants selected for this trial are a pair of Yankee Bell Peppers which were picked for the
fact they were visually identical in number of leaves, height and initial
vigor.
Soil Media:
Scotts Premium Topsoil – Scotts was picked because it is not
enhanced with wetting agents, fertilizers or any other additives and is pine
bark based making it resemble the standard growing mix of most nursery
operations.
Fertilizer:
Alaska Fish Fertilizer – Used as a basic water-souluble
liquid fertilizer.
Sunleaves Seabird Guano Pellets – Used as a long-term
fertilizer and applied in pellet form to soil surface.
Black Hen Composted Poultry Manure – Added to soil when pots
where half full to act as root stimulator.
Black Magic – Home brew Fertilizer, used in the early trial
to offset transplant shock.
Duration of Trial:
The trial officially runs for 12 weeks ranging from June 13th
through August 29th 2014.
Method of
Recording:
Results will be recorded using plant height measurements
combined with a weekly photograph of the subject plant’s progress over the
course of the primary trial period. A follow up comparison of root development
and fruit yield will be performed after the primary information is collected.

Summary:
When one considers the factors of the unusually wet weather,
the lack of an August drought and the fact that at points the temperature was
for days in a row well below seasonal averages the trial paints a picture of
possible performance issues. While it is true that the pictures tell the
progress of the story the lack of hot sunny days proportionately speaking did
likely hamper the normal progress of the plants in the trial. The final three
images in the series do indicate however that the conventional nursery pot
produced a more vigorous plant. Over the course of the trial the conventional
plant had a standing lead of at least an inch of height at all times and in
some points far more. To that one could say that the smart pot plant had a more
steady growth pattern while the Conventional grew matured and set fruit sooner.
The rapid growth may have presented a new form of problem in that the
Conventional Pepper suffered a calcium deficiency whereas the Smart Pot plant
did not. This calcium issue resulted in blossom end rot on the conventional
pepper which has made fruit size comparison not possible in the time frame of
the trial. It could be that due to greater amount of soil in the Smart pot the
calcium content in the soil is not yet depleted. Due to this unofficially the
trial continues until the end of the warm season as a whole so that the
fruiting factors can be compared.
In summary it seems as though the conventional plant has won
the trial by successfully doing what one might ask of it faster and earlier
than the comparable Smart Pot plant. The additional Costs of growing a plant in
a smart pot* is a factor that cannot be ignored for the purposes of the trial.
From a production perspective there isn’t a justification for the smart pot economically
or for efficiency purposes. If Smart Pots were available in directly matching
sizes to their nursery pot competition at a price that was competitive the two
greatest factors in keeping solid-wall nursery pots in production would be
rendered null. The results of the productivity aspect of the trial is still
pending and in both plant’s cases their most developed fruit has been removed
so that two new fruit can grow side by side to see which produces the largest.
For now the smart pot isn’t the smart investment but this study will be
revisited before the end of the year.
*Smart Pots cost an
average of $10.00 to prepare for growing crops whereas nursery pots are at best
$3.00 -$5.00.
With the 2014 primary Garden trial discussed thoroughly it’s
time to talk Market! That’s right this Wednesday (2:00-6:00 pm) and Saturday
(9:00AM – 1:00 PM) I will be at the Fayetteville Farmers market selling aloes
galore for the last week of Sparklitis month. This is your last chance to lay
hands on the rare and unusual aloes before they are taken off the sale racks
for a few months. Some of the plants may return during the holiday months but I
wouldn’t bet money on that one! The
Fayetteville Farmer’s Market is located in downtown Fayetteville in the
Fayetteville Transportation Museum Property on 326 Franklin Street. Without further delay here is this week’s
plant list which polishes off this week’s LITFM post, I hope to see you at the
Market.
Southward Skies: A
northern guide to southern Gardening
This is the second
edition of my book, which was published using data compiled from several years
of test garden operations. It’s written to aid gardeners of all skill levels in
successful garden methods that are targeted for the south east but had proven
to be a valued resource for gardens across the eastern coast. It’s certainly a
good gift for that gardener you know or for yourself if you’d like to have a
reliable field guide. The book costs $25.00
and we do take checks for this item, you can even have it signed.
