    Diy FOTOP grow board 280x900x2.0mm (L29.52"xW9.18")

    And what about you keep both light in the tent? Half the new led run a little smoother than 600watt maybe 480 driver..(i do like the 4 board options and put your kingplus in the other half? This way you’ll get full light accross the whole tent? Also you mentionned with the sucking your tent...

    The Chinese Quantum Board Knock Off Builds

    I have 2x 240 driver in a 4x4 running at 520w.. i feel I could use a little more power especially on the sides of the tent so 4.5x4.5 might be a little stretch if youre planning to fill your space wall to wall with plants. If its not too late id aim for a 600 driver instead assuming your boards...

    Going to try LED lighting again... Recommendations?

    Aim for 30-50w of efficient white led per sq.ft. Probably a little more 40-50w since youve been using 2 DE in 8x4 Which mean about 1200w-1600w you could build something with 8 cobs like you could use 32 of them for a gain in efficiency... do you have a budget? There is a tons of option.. but...

    Industrial Lights ? Help

    If your question is will it grow ? answer is yes Is it efficient ? Most likely not probably in the 100lm/w similar to blurple If you got them for free and could use the extra light in your grow space yeah sure just use it.. there is better more efficient options available but it will still grow...

    Do i need a potentiometer?

    If you buy B type model and dont have a potentiometer it will run at 100% capacity.. so you dont need one unless you want the capability to dim your light

    First grow - 4x4 tent with 4x 304 LED boards

    Update : I took out the right girl about 8 days ago and chopped the left one yesterday.. The first one has dried and put into jar for curing.. ended with 9oz of good buds and some larf but not a lot so my scrogging was a little better than the last grow. The second plant is looking...

    About to bin my 3 month old plant!

    The issue is clearly due to your medium.. doesnt look at all like temps, rh or light issue so by elimination thats the problem.. but what exactly within that hard to tell.. root rot? When you transplanted did you look at your root were they brownish or more white? Otherwise it could be relating...

    About to bin my 3 month old plant!

    Damn man must be one of the worst looking plant ive seen in quite some time not too sure how you ended up getting to this point.. have you tested your ph? Your soil is maybe not in a good range creating locking of nuts.. there is probably better way to test it but water your plan when its dry...

    g/Watt by Lamp?

    General rule of thumb is Hps and blurple light =0,5-1g/w Efficient white led (quantum, sammy strips, cob, etc) should yield between 1-2g/w.. but as mentionned in the previous post there is so many other factors to consider, temps, rh, feeding, strains/pheno,c02, etc....

    lighting for a 2x4 closet grow

    Nah 3 at 300-320 would be best and 2 at 260 will be fine but not to the point to have perfect coverage all over the space.. because I currently have 4 boards in my 4x4 running at 130w each and I feel id benefit from a little more power.. so half that in a 2x4 (260w) will do but with 3 boards at...

    lighting for a 2x4 closet grow

    Get yourself about 300w of qb like light like strips,cob, qb, etc..whatever you prefer, fits your budget or else.. and you will blow 6-8oz easy in your 2x4/2x5 space Since you already have a QB get yourself another one and youll be set, best would be 3 ran with smaller current each but up to you

    5×CXB3590 3500K LED @1400mA

    On my second run of WW.. depends what hot means but I can say its a strain that can take a beat up and jump back from it everytime.. very newby friendly (or forgiving lol).. and I personnally really like the high from this hybrid strain

    Cobs and leaf tacoing at the top

    Picture would help but if you left them at 12 inch for the last 40 days i would put it back at 12 inch for the remainder.. it may be on the high side of light for them but they managed to deal with it for so many weeks not sure why you would want to change that at this point..
