Hello 3.456 chips Spain @Rocket Soul @coreywebster

qkwin 240w tent 2x2 - only 60% of power

If I am from Spain, I know these cobs are somewhat old and are not the most suitable, but I bought them to carry out tests and comparisons, at cannabiscafe we have done many tests with spectra and clones. You find few differences in the production, but in the flowering time and it can be...

I have some citicen 2 cobs of 2700k cri 97 and a pink PRB, I have noticed faster flowering, the maturation ends sooner. 54 days of flower since seed, now I have grown the same variety from clone again and with another 5000k+3000k and 660nm panel and the flowering is getting longer.

The measurements are not always at the same height and it is something to consider. So the efficiencies are somewhat distorted, there is a reason why it puts an asterisk in the measurements.

Of course, I don't I only applied it in the first weeks when I detected that deficiency, during flowering I don't like to use foliar applications but I had no other choice. Thanks for the clarification of the deficiency.

Hello Day 31 at 12h. It seems that the problems never arose after the foliar applications of epson. and new baby crossing the Atlantic for the garden pure michigan to Galicia ❤️❤️

WTF

Where do you see claw leaves? because I don't see any Thank you for your comment trying to help

foliar treatments with epson salts.

@Rocket Soul , If you put the circadian cycle of plants into Google, you should get a lot of articles. I am Spanish, so if I put it in Spanish I get many articles, I wouldn't know how to tell you in English. But I leave you some links to those articles in which I learn about these studies...

It is a very widespread myth. The use of far red 10 min. before the day/night photoperiod change has no influence. This is regulated by the circadian cycle of plants. There are many studies on that and they did not depend on distant reds to know when it was time for sunrise or sunset.

It seems that they are recovering, the new shoots have a good color and the leaves with spots are not getting worse. I did some foliar applications of Epson salts.

thanks bro we will see how they evolve

Hello, the new leaves are losing their color on top. what do you think of magnesium/sulfur or other nutrient deficiency? Or too much light?? i use supersoil and 3 gallon pots Max 24 / Min 19 grados Celsius Max 71% / min 43% the space is 60x60 cm 190w panel distance 55 cm 500/600 ppfd with...

The spectrum is not a different topic, you can put 1800 PPFD of a green spectrum and that study would not tell me anything, the same as that study that uses purple LEDs with blue/red and without using the other bands of the spectrum, especially green/yellow and infrared that affect the leaves more.

Do you think the spectrum used in this study is a good one?

The real power will be +/- 660w and the other +/- 60w remaining will be the losses generated by the ballast.

Con HPS, las plantas pueden aceptar una mayor densidad de fotones que con LED sin mostrar deficiencias ni signos de estrés en las hojas. Para mí el problema está en el espectro LED (especialmente la falta de IR) y la relación de los colores entre sí. Los científicos utilizan el NDVI para...
