Yeh i realized that after i posted whenever i search snything relvance not recently activr brings it up

Thier are variables here dude you could have 2 high end leds and 8 plants in 5 gallon buckets of coco top feed or flood and drain or dtw on a 2 month veg but hid lighting yeh your gonna need 1500 to 2000 watts of gavita fluence or growers choice led or cobs or 1800 to 2000 watts of cmh or 3...

I been waitinf to pull the trigger no grow journal but here is a pic of them when i first put then under the lights vegged them for 10 days or so under them because my room was full upstairs and this room wasnt fully done at the time ill post as i go though

1 800 gph feed pump out of a 55 gallon food grade barrel to top feeding 9 inch rings through half inch line on 8 separate ball valves one per pot to always balance the feed out between them. The return is a 345 gph set for 1 hour the 800 gph set for 30 mins valve shut a quarter way

Im running two.roi 720s 720 boost to.800 watt coco top feed 2x a day recirc. Gh supps advanced connie base what do you guys think 5 gallon pales 70/30 coco/hydroton. 2 month veg lmao hoping for 6 to 8 lbs these lights are AMAZING better then most cob arrays efficacy wise nothing compares but the...

Is that with Co2 and hydro??? Curious

That studies old news dude 11 years old lmfao YouTube Bruce bugsby and get your notepad out professor of horticulture science

That's not running a single light that would be in a pattern formation work over lap accounted for I haven't done it I'm currently pulling about 1 to 1.2 gram a watt in a cmh/hps over lap perpetual in coco recirculating flood and drain and other half dtw . I'm referring to what I know and have...

Co2 makes 2000 ppfd plus possible according to studies going on now where exactly the diminishing returns exist are above where led can produce without bleaching because of how close you have to be with em. If.im running 1700 ppm of co2 in a room where my canopy temp is 82 degrees exactly with...

Really dude listen photosynthetic photon flux is measured as a whole photosynthetic photon flux density is measured in a particular spot at a particular distance away from the light source hense the added word thier density is how dense is the photo activity going on in that one particular spot...

I don't have an accurate number because I'm running perpetuals it's a 315 cmh 600 super hps for one 5 by 5 a 630 nanolux dual bulb 630 and a 1000 hps for 5 by 10 I have two rows of 4 in the 5 by 10 and 4 In a 2 rows of 2 under the 315 and 600 my last pull was 18 zips and I didnt have the 315...

Not necessarily and ppfd is to general that's only good for a par map and setting readings with a quantum sensor. The correct term here would be ppf or umols/j efficiency. Co2 could easily make a better Gpw because the plants can handle more intense light up to 2000 ppf if co2 is in the 12 to...

And after all that bullshit I just typed the point was now that I have more experience I feel it's my obligation to chime in for the newcomers or info seekers.

And also now I have 10 or so pulls under my belt first one was about 1 zip a plant last one being 5 to 6ish running 3 batches of 4 to 5 in a 10 by 10 under 1600 watts of hps and 945 watts of cmh with a led quantum rail for supplement. Basically 3 5 by 5s in a 10 by 10 room

Yeh man I been reading this thread for 4 or 5 years just got growing Last june jumped right In with perpetuals not knowing a fucking thing months of head scratching and dialing buying one little thing at a time went from a t5 to one cmh then another 315 then a nano 630 then realized I needed red...

Not true at all I'm running at 12 to 16 inches away with leaf temps in mid 70s

I know this is old but do you mean better as in like the present day open hood setups.

Also most quantum sensors dont detect past the 700 or 750 nm range so with that being said thiers alot of light that does affect the growth that due to recent studies is actually photo reactive far red is referred to as the forgotten photon because people never really knew much about it until...

Its designed for the far red which horticulture studies have shown by professor Bruce bugsby that far red tricks cannabis into thinking it's in the shade which inevitably produces more biomass to avoid the "shade" and absorb more sunlight increasing photosynthesis it's better if combined with a...
