Are these cobs dimmable?

 

All LEDs require a minimum voltage to fire. Therefore no LEDs can be dimmed like incandescent bulbs.

That said, COB LEDs can be dimmed to some degree. down to 30%? Not sure.

Not necessarily. It depends on the driver. I can dim my Fluence light down to 10% or maybe lower (I haven't tried less than 10%).

 

ETA: LEDs brightness is actually dependent on the current flowing through it, not the voltage across it.  The voltage drop across the LED is pretty constant (and you're right, there is a minimum voltage below which it won't turn on), but the driver varies the brightness by shoving different amounts of current through it, not varying the voltage across it.

Isn't it also true that the amount of current that can go thru a device will also be dependent on the R value, as well as voltage? You can take a 12v LED (or any light bulb for that matter) and hook it up to a 1000 amp 12v battery without burning out the LED. Yes, you can in fact vary the brightness of any bulb type by varying the currant at constant voltage using a PWM circuit design. That's one of the reasons why many LEDs flicker.

LEDs have a series resistance, but it's usually pretty negligible compared with other resistances in the circuit. You can find the internal resistance of an LED on the spec sheet.  You control how much current you drive through the LED by using an external resistor sized appropriately for the voltage applied across the series combination.  A 1000Ah battery just says what the battery is capable of delivering - but it is the load that determines how much current is drawn at any given moment.  If you put a 1 megaohm resistor across a 12V car battery, you will only draw .012 mA, but put a short across the terminals, you will draw so much current that it can weld the short to the terminals.  That's why you can safely touch both the + and - terminals of a car battery safely - body resistance is about 300ohms, so the most you would draw is 40mA which is not perceptible. So, LED drivers are basically a constant current source varying voltage across a resistance in series with the LED.  Varying the voltage across the series resistor varies the current that will flow through the LED.

 

Yes, you can dim an LED using PWM - but you shouldn't really notice any flicker as long as the switching frequency is high enough.  Most high quality LED drivers do much more than put a PWM voltage across the LED though, they are a constant current source.

If I wanted to safely sanitize the soil capsules for my Click & Grow, is there a way to do it?

 

I would use a solution of pure H2O2 as I described in a post above, or use a solution of a product called UC roots, which is hypochlorous acid derived from calcium hypochlorite.  But, I don't know if you really want to do that.  One of the reasons growing in soil works is because of beneficial bacteria and fungi living in the soil.  Sanitizing your soil will kill anything bad growing in it, but will also get rid of all the good, and will make it more difficult for future plants to use that soil, unless you add some compost (which is full of beneficial bacteria and fungi).

 

It might be better to use a product called Hygrozyme (or one of a bunch of similar products) which is an enzyme that breaks down cellulose.  So, a soak in that solution will do a good job of breaking down any remaining dead roots in the soil, and turn them into products that are good for future plants - plus the spaces left by the roots add aeration to the soil.  Then let it dry out which will get rid of anything anaerobic that could still be hanging around.

While I was enjoying my evening shower I had a thought:  what about baking the soil capsules?  Or as Click & Grow calls them, Experimental Plant Pods?  There are no dead roots.  This is something close to synthetic soil formed to a frustrated cone.

 

What time/temperature destroys fungi responsible for damping off of seedlings?  Note we are talking about only a couple cubic inches of "soil".  My most recent pea seedlings were overwhelmed and destroyed by a white fungus.  As far as I can tell the pea plants turning brown was a different problem, which I believe was heat.

I am still having to endure the ugly visuals of frost damage. The recent rains have prompted lots of new growth. The citrus (orange, kuquat and tangerine) are going nuts. Walking to the mailbox is almost overwhelmingly scented The herbs are showing off. I thank Lucy

General tip and FWIW,

If you're doing some sifting of soil, peat, compost or whatever for making your own mixes or whatever.

I strongly recommend the gold classifying sifters with stainless steel mesh...they come in various mesh sizes (sets are available) and fit in the top of a 5 gallon pail.

1/4 inch being the most useful size, IMO.

SE GP2-14 Patented Stackable 13-1/4" Sifting Pan, 1/4" Mesh Screen

These are a MUCH better option than the ubiquitous bonsai sifters.

I planted 21 red potatoes and 300 onion sets yesterday.  

 

300 onion sets don't sound like a lot when you're sitting in your kitchen in January ordering.  

 

It's different on April 8th when you're actually planting them. 😂

At that quantity, it's almost worth looking into a vacuum or vibrating seeding machine!

Nifty notion. I'd seen a couple of his seed-saving articles on the Mother Earth News website, but didn't put the pieces together until I'd Googled him.

It's also easy to plant 40 feet of bush beans in the spring, but then dealing with the resulting quantity of beans is something else. One's enthusiasm and optimism are endless but one's energy is not. I don't think I've learned that particular lesson yet.

 

I am still guilty (see above) of buying a lot of strawberries or mangos to make jam, but when I'm confronted by the task my zeal is much reduced.  In the case of mangos, they require some days to fully ripen on the counter so there's a little time to get used to the idea. But strawberries wait for no man (or woman).

Managed to pot up the bullhorn pepper I planted this year and move it, the summer before's bullhorn and my curry tree under protection right before our first frost of the winter. Hope I got enough roots for the bullhorn to survive. It will be interesting to see if the one that's a year older makes it through a second winter - it's quite a tree.

 

I'll probably try some winter crops like broccoli and garlic but my luck in previous winters has been poor.

Aurora peppers are about 4 inches from seed

 

Poblano the same

 

Oddly enough, NONE of the pepper seeds we saved on our own (Padron, Shisito) sprouted...

Were the fruits they were harvested from fully ripe?

Full ripeness is a requirement for viable chile pepper seed.
