thanks! is the 80-144V something written on the spec sheet that i will have to check each time, and i would have to math it out on my own by adding the V ratings from my strips together and making sure it doesnt exceed my driver? the issue with your example is 4.4 cobs will fit there but a max...

i did actually! thanks. i just wasnt sure why he goes 120~W for a 2x2 and uses a certain strip in his F series build. i take it most F ones are just great and can be swapped?

can you explain this further? i thought more power gave more light unless you mean lm/w is sometihng i can control somehow?

how did your yield change going from 120 to 90w? were you burning them?

with 30-40w/swft, total of 120 (maybe 100?) - 150W total in a 2x2. What i dont get is how to find out what driver is suitable for these needs. any ideas?

Curious what people go with using lm561c diode strips or similar. i recall seeing 30-40w/sqft so 120-150w? ive only found 1ft 50w strips so id be stuck using only 2 or 3.

what is the vpd stuff you mentioned?

for ridding it entirely? do you have a general suggestion on what things need to be done to remove it?

what are the best ranges to be in to stop pm and what ranges are bad to be in?

Did a large amount of plants per 4x4 (~30) and combatted PM for multiple grows and they keep resurfacing. What's the way to get rid of this? Already do sulfur and inspections each day. dont have a dehu though, any suggestions would be great

sorry to bring up an old thread but pretty much only small grows would try to do some "emerson effect" right? normal/larger grows wont care, and thus CRI 80 will suffice and CRI90 wont help (the larger/big light grows)

sweet results, how long was the flower time after the 10 week of clone/veg? how do you like the QB's so far compared to the strips? i figure you cant tell yet for quality/yield but its probably easer and nicer to set up compared to strips and is cheaper?

nice set up! how much do those heat sinks cost? and any reason for deciding a qb vs an led strip? i went for led strip out of convenienceand threw them on u channels as a poverty heat sink which seems to work fine, though metal was a lot more expensive than i though..., always curious about...

4lb is insane! nice! how long veg and flower did that need and do you remember that strain specifically?

0.7 - 0.8 seems high. got a quote from hlg indicating their 550v2 model runs at 480w and replaces a 1000w se gavita, and the 600w version replaces the 1000w de gavita. any reason for 0.7-0.8 .... is it assuming a lower quality led? furthermore, is there any other adv to led aside from...

nice, those mid scale were like 10 4x4s i presume? scrog seems the way to go for personal since it seems much less work to manage. does flower time defintiely take longer though compared to a sog?

thanks. when plants are close together, PM and bugs and budrot become more common? why is that? any tips on combating them? not going for 9, just was wondering in terms of proper sogging and min/maxing stuff out of curiosity

got clarification, the 2.5 still needed about a week to cure, the 2.8 was full dry

what do you consider sufficient and not 'too much' light for a 4x4? i only brought up 4x4 since people either use 4x4 tables or tents most commonly and the current simple LED solution of HLG covers a 4x4 footprint ideally. greater yield with same power in a 5x5, is this due to penetration? got...

can you shed light on how you made those LED's? looks sick!
