Mars-Hydro LED Grow Light Discussion

[Mars Hydro]

Thank you so much my teacher
I have faith that when growing cannabis is legal in China, I can grow some good plants hahaha

6.2-6.3 in soil. Lime to keep it there.
Hydro 5.5 to 5.8 but a lot of growers start at 5.2 when they swap water to allow for the fluctuation that will eventually land it in the sweet spot

Hydro does good at 5.5 to 6.5. i start mine at 6.0 as my pictures show she does just fine.

I heard that PH is 6-6.5 is great in soil, no sure the what PH is perfect for hydroponic.
PH 8.5 really high, but the plants don't have any issue, that's the point

Here is a PH chart for hydro and soil. Hope it helps someone.

sara will you be brining out more cob leds ?

 

[Skullman420]

what is Mn? (orange line) I see you won't get any of it with pH 5.8 in hydro. Interesting

Here is a PH chart for hydro and soil. Hope it helps someone.

 

[Skullman420]

I figured it out. It's Manganese. A pH higher than 6.0 across all substrates will render manganese unavailable to the roots. Manganese is essential to chlorophyll production and photosynthesis.

So hydro lower than soil?

Hmmm, now we haven't any plan to produce more COB, once the 100 pcs sold out, we might don't sell COB

 

[Mars Hydro]

Yup

Thank u for confirming, I feel like I'm a little closer to become a real grower hahaha

I'm still a little confused, I googled Mn is mobile nutrient, the plants can move it from older/lower leaves to newer leaves, when the PH over 5.8, the roots cannot absorb Mn, the older leaves will send the Mn to newer leaves, if that the older/lower leaves will Mn deficiency, Is that OK?

Here is the most recent photos of a Blue Mystic auto and a Northern Light. Notice what light they are thriving under.
