The garden of a lazy we occasionally.

[olivier75]

Hi,
The green bin is used to hold the pots, it is pierced, the soil falls into it which is not annoying on the contrary, the roots continue. I also used it without the pots, which becomes a classic mini greenhouse. We can actually return the greenhouse but I found large planter saucers for 4 pots, very useful when I abandon them for 3 weeks. Photo of the saucer on April 7, 17.

Photo of my DIY this evening, hoping that it will be enough and that the wavelengths are the right ones. it's RGB.

Ok thank you for the illustrated answer!

I think to buy me the model of the site which you gave the link. But as a saucer, I will use the transparent cover lined with a cm of clay balls with a little water at the bottom to keep moisture at the bottom of the cups ...

Plants need a lot of light - finally, to express themselves correctly, plants are adapted to intense sunlight.

I found this, which seems coherent, on this site: http://guide-de-culture.com/lumiere.php

What light power to use?
-The light output (expressed in lumens) depends on the surface to be lit:
150watt (15000 lumens) -> 0.3m2
hps 150 watt very low light penetration about 50cm high
250watt (33000 lumens) -> 0.5m2 ideal culture 0.5 m2
400watt (55000 lumens) -> 1m2
600watt (90000 lumens) -> 1.5m2
1000watt (120000 lumens) -> 2m2
-For flowering, plants require a minimum of 10000 lumens.

Didier,

I will try to measure my LEDs by Saturday, the photo corrects but they are quite powerful, the green is connected too, even if it is only very little useful.
This evening, the 2-day salads, develop their cotyledons and do not seem to spin. The first tomato which has developed its aerial part also begins to open its cotyledons to about 1,5 cm.
Anyway, I'm pretty confident, I will take blue and red LEDs for tests and prepare well for next year.
Even if it means losing comparisons out of season.

From my memories of youth, HPS (sodium) lamps are not recommended for the growth of plants whose names are not said, because they have an orange spectrum. For growth it is better to have a blue spectrum with MH (mercury) lamps ......
After the years have passed and they are now making light bulbs mixing spectra and even energy saving bulbs but for which you have to drastically reduce the distance bulb <-> plant

In any case, I can say that a HPS lamp of 600 watts .... well it fucks the eyes and it heats a lot too!

[Did67]

Yes, we must forget that.

I cited this article, precisely because it gives "lumens" - therefore a luminous intensity. Data which is gradually spreading in the labeling of ampoules ...

I don't even know if the old HPS lamps are still selling - it was, during the incandescence, which had the best performance ... Then there are the compact fluorescents (special greenhouses or aquarium) and then the LEDs (predominantly red and blue / purple in greenhouses) ...

I only retain, in this table, the orders of magnitude light intensity in lumen. The rest is ancient history.

Hi,

Small follow-up; the LEDs seem to be enough, the cotyledons are dark green, the stem is straight in the center and turned inward for the sides. Next step the real leaves ...

Hello,

The led system works well, they are now white, classic and "corrected" with an additional red led.

It is necessary to inform me a little more about the first needs of the seedlings, among others on the UV, nonexistent on these LEDs.
The shoots this Tuesday April 3.

Olivier.

In the vegetable garden, visited this weekend, the season is off to a good start. the autumn spices have not suffered any losses, those of spring are more or less starting to come out, there was a last series of red onions yesterday.

Some Maches start to rise, peas, beans and spinach rise, despite the gels, -4 again at the end of last week.

The hay laid in the fall has melted well, much more than last year, proof that the soil is getting quicker? It will be recharged this summer with the first mows, in the meantime, the straw completes the gaps.
The potatoes have just been planted in the hay with the dibber, with an addition of straw on top.
