nice build ! 3000k + 660 or 3500k + 660nm ?

Hi sir if I use ro water 0.0 ec, fertilize with canna coco a + b fertilization program of the official website, put calmax (grotek) up to 0.4 of ec (of 0.0), 20 ~ 30 % runoff

Hi guys. I have problems, I do not know what will happen, you have more experience, it's my first coconut. the leaves on the floor below show those symptoms always, I can not find the error Pot: 11 liters. Ph: 5.8 Total Ec: 1.3 Now 1.6 Calmag 0.4 ec (clean water) Canna coco Water temperatures 20...

Hello ! how they calculate umol/j ?

what madness with a sstx heatsink, have a homogeneous dissipation, and find out the circuit, I think that with a bigger pcb it would improve even more.

I still do not know what reds use ..... nichia? lumiled? osram? 630nm ?

impressive, HLG is doing very well, it seems that the chip luminus is very efficient, the reds are also luminus?

if I expected not to be burned, I was thinking of using a source of adjustable power (rs-15-12) again I have a doubt if I connect 2 for example would be approximately 0.22A, with this new source would it be necessary to regulate it so that they consume the necessary or simply consume the necessary?

then the driver does not work for 1 single, I'll try 2 or 4 as I go ....

Thx , I'll try two as I'm going, here's the technical data Electrical Characteristics Typical Voltage: 12V DC Current: 0.11A Start-up Voltage: 6.0V DC (@ 100% PWM) Cable Length: 400 mm

hello bros, I have not been able to make these fans work, I do not know if something is doing wrong or connecting badly, I counted the black with the red according to the scheme but still I can not get it to work. I'll be forgetting something?

would be better more points of light 8 1216 at 50w each or would be enough with those 4 1825.

it is efficient to run 4 citizen 1825 to 150 each for a 44x44

I desing pcb, deep red, royal blue and 385nm 2:1:1. 85w~90w.

I was in a difficult situation between pp 2.0 and mimosa, I went for mimosa bought it from seedvaultofca1 on instagram, I'm not from the USA I hope they arrive at the end of January and I want to see what phenotypes will come out.

Add deep red and royal blue;)

Mimosa or purple punch ?

I suppose you are understood of PCB? I buy in meiju I do not recommend it, look for another company. prepare your ass if you bought in meiju

yes mate, pessimize quality. the cables did not fit into the connectors (which were not wago).
