all my last grows were flushed at least 3 watering before chop, so can my soil be considered as flushed ? (I know many people here don't flush before harvest, but it's not the point here ;-)) also on the BlueCheese the very new leaves grow in thin shiny blue blades, just genetic or P excess ?

Hi guys, Im quiet new at this game and this time everything is going wrong :wall: so I really need your help I have a c99 vegging for 20 days and a blue cheese for a bit more than a month So the blue cheese: with the white balance of the camera seems like she's hungry, but my eyes see her...

Beatiful grow man, your glue is looking extremely dank :clap: do I understand it right, that you've noticed faster maturing/senescence, using 730nm at late flower ? and if so, were you using them during daylight ? and hyroot: your panel is so classy, love it :cool: maybe a little reflector...

Hey man, don't worry you can run it, your effeciency might be a little bit higher than on 230V

Thanks a lot for all these info, would take a moment to process bongsmilie I've also heard about Uv helping to produce thicker stems and protecting against deseases and genetic shifts during veg stage your article says the opposite about morphological differences, so I may be wrong ... Also...

okay we're on the same page here, I've played with 660nm in my flowering room during these last year, tried some weirdo time schedule ... finally can't tell a difference in final bud aspest, g/w ... except for the morphological part, if you have stretch issue, they are the solution just made a...

Yes of course I know that, but I m speaking about reducing current by dimming, so both voltage are equal. 285*0.5 = 142W, 285*0.7 = 200W maybe we could transpose it on the load curve, as power proportional to current in the datasheet case. so running this driver at 500mA is equel to run it at...

Soooorry man, makes sense now and I'm speaking about losses created by dimming the current, like I said a 185h-c700 ran at 500mA are thoses losses negligibles ?

are you referring to the fact that the extra volt from the driver would be "converted" to an increase in current ? like when you're exceeding the voltage output of a driver, its current output may decrease I'm running right now a poorly chosen driver/cob combo (LPC-60-1400/ V18 ) and I can...

and why is it so important to have a high Pfr ratio in flowering ? instinctively I would tend to do the opposite with 730nm, since the stretch is over I believe a 680nm led, while having a similar photosynthetic effeciency than a 660nm and not acting on phytochrome state, would make plenty of...

Hey guys, is there a curve "Effeciency vs Out_Current" for the hlg185h-c anywhere ? I feel a bit like that question has been asked several times, but can't find the info. by the way, can't see why you're saying that this driver would be pulling 2A through the 3590, everything seems fine to me...

Very true, 4 little epistar @700mA in a 2*2sq and it will stretch like hell :fire: by using them at nightfall I gain more or less 4 days on each grow, the stretch phase finish way faster and while I've been thinking about the phytochrome action on germination I got lost at one point ... the...

thanks a lot, I was wondering about it for a long time :wall::weed: edit: and while you're here I have a kinda dumb question, I was planning to dim throught a vdc signal clockwisely (rising slowly, then a sinus and decrease ) and make that signal pass throught a 0-100k to increase intensity...

so you mean there's something (a RC maybe) that is converting the pwm signal to a 1-10V, at the "dim input" ... am I getting this right ? so that means that a pwm dimming won't make led flickering ? (I don't mean for our eyes, but on an oscilloscope for exemple)

thank you for your reply, unfortunately I don't understand what you're saying :eyesmoke: no dimmers are already installed, the triac (which should be added) take off some power (the absent area on the waveform) from the input of the driver, which results in a decrease of the output power ... My...

I've found this one http://www.mouser.fr/ProductDetail/Mean-Well/PCD-60-700B/?qs=sGAEpiMZZMvV8Y9YugmIguAUY71TS/YqbNBkecjAchclw5YviBbDRw== not perfect, but it matches ... but its dimming is done by a triac on the AC side, basically like the dimmer on halogen lamps ... seems a bit weird to me, any...

Hello guys, I'm searching for a driver able to drive 2 vero18 + 3 luxeon 660nm (65V) at 700ma with dimming option so a 45~50W driver @700ma, any ideas ?

Very interresting build, I would love to see some data about the 470nm effect on bio-morphology, that's kinda low in all cxa/vero ... if I remember well, there's something about transpiration and cytokin cycle here. I'll follow your grow closely, good luck

Hey guys, I'll power a 250m3/h Torin, throught a multi output transformer (80, 110, 160, 200, 230V), with its outputs linked to a selectror, one of the position would be the off one ... My question is, should the off position, be next to the 80V or the 230V one ? Nothing seems wrong with...
