Are these good? This thing shows me ph 7, after 2 times adding acidic water (I added citric acis to water, ph around 5-6), this thing still tells me its 7. And fertility is too little for a "good" soil I bought in local shop and added nutrients..

What is the best way to get ph down - soil grow.
For ph up - lime?
I cannot find any liquid "ph down or up" solutions where I live.

Ok so ignore the numbers like 1000w because they are nonsense numbers.

The 1000w is 180w-200w
The 252w is 140w
The 54w lights I cant tell but probably 15-25w (if you can find out more info on the page do so)

But as a guess lets assume the lowest number on those multi bulbs.

6x 15w =90w
+ 180w
+ 140w

410w total.

With lights like those you want more watts per square foot than with more efficient LEDs
I would be aiming for at least 50w per square foot
So say 8 square foot you might want to try 9 since that's a 3x3 tent.
This is a best guess based on what little I know about low efficiency Blurple LEDs
So its a very rough estimate, best thing is to try 9 square foot and be prepared to compact your grow space if buds turn out airy, or start compact and once you know they are producing dense buds expand slightly.

Like I say rough guess since we really don't know the true wattage of the smaller bulbs you have 6 of. Its very unlikle they are the wattage listed, LEDs are run low power so they last longer.

For your other two questions

No idea on height from canopy but its related to light intensity, you will have to start off maybe 24" and work down once you know they are not causing any light burn.
You might hit 1gpw if your good at managing your canopy but I couldn't say either way. If you get 400g dry your doing very well. I would opt to imagine less so your not disappointed.

Hi fellas, I have been growing cannabis for 5 years... i was grew in indoor with hps, led lights & outside... I wanna ask you something about led's.

i have these leds;

-6 x 54w (18 led x 3w)

-1 x 252w (84 led x 3w)

-1 x 1000w (100 led x 10w Double Chips)

Please check attachment image for review the leds i have.

here is the my questions...

-how many square meters (or sqf) should I use these leds in total?
-how much distance should remain between plants? (I would like you to write the required distances according to 3 different leds model)
-how many grams can I produce per watt (with all these leds)

(Sorry for my English... )

Thanks.


Peace&Love
