I've heard, and was told when I purchased them, to have 1mm of distance from bottom of reflector per 1watt of power for the gavita de.
So mine at 750w should have around 750mm of distance from canopy.
2ft distance from the 1000w de is realllllly pushing it, IMO. The leaves may not even be able to handle that amount/intensity of heat/light...

You might be surprised how low the number is, especially once you factor in how many watts it took to achieve it.
I'm pretty much ready to shitcan the remainder of my HPS flowering lights.

ok, how bout the ppfd of a 600 watt hps or mh with say a plantmax bulb? i only ask cause up till now thats what ive been using. had 2 600 watt hps and 1 400 watt mh over my flower area.. iv done well in terms of yield, but finding a good producing strain with an equally good high has been a problem..ive run over 20 strains in the last year and i really want to settle on 1 or 2 rather than keeping so many dif moms all the time.. as of now my best 3 have to be dynamite and island sweet skunk by next gen and 2 bubblegums by th, but i still have 2 dif skunk#1's a sensi and a seedsman original. 3 different nl strains,2 different criticle mass, lemon kush, og kush, and shit moms.. i think im getting rid of the shit,lemon kush,og kush, and 1 of the bubblegum moms..but still need to cull more to get to the 2 or 3 best..
my room will be finished soon, took down the hps/mh put up 2 cdl's but plan to put up 3, pulled out 4x6 dwc/undercurrent table and put in a 4x6ft flood n drain table..still have a bit more to do before i can start new journal with cdl's but i have plants under the cdl's that are 1 week in, already i see a huge difference as plants are not stretching like they did under hps/mh lights..oh and the color of the leaves under the cdl's is really cool, they almost look like different plants as under the hps/mh they look green but under cdl's the leaves almost look purple as they are a very deep green color.. but i know its just the spectrum going from a majority of an orange room to a very white light room.
anyways please let me know the ppfd of a 600 watt hps 2 ft from bulb so i can know the difference..
also any recomendations on a strain that yields are high as well as potency, and finishes in 8 weeks or less, indica dom is preferred with a 1 week veg from rooted clone to end up around 3ft tall after stretch.. i have over 100 different strains so i cant list them all but hope 1 of them are a winner.. have blue dream, blue power, blue mystic,blue dynamite, 2 different blueberrys bcbd and spliff, 5 different bubblegums th,serious,female,nirvana and white lable. i have lots of land races and just about every stabilized hybrid or true breeding strain available from seed co's. anyways give me a few different choices and hopefully ill have 1.. my wife wants me to try papaya,sage n sour, ultra sour or berry bomb and she loves the th bubblegum and the island sweet skunks hubba bubba smell.
sorry bout the off subject ramblings,lots on my mind wright now..

Hey no prob....Watch the Berry Bomb if you grow it.....Root temp sensitive.....More so in hydro!
I would like to suggest you try BLACK RUSSIAN from Delicious Seeds......Good yields, easy grower and packs a real good punch! (One patient calls it "stupid gas" and that's a good nick name for it!)
You might take a look at the Iranian strain family of plants at Dr Geenthumb!! Chem x Iranian and x Diesel and x OG and xG13 I've run.....They all are good with Iranian X OG having some abso - fucking - lutely FLY phenos !!
Don't be put off if any of them are sold out.....During the fall and winter, everything he offers comes back on line....BTW, his prices drop during the winter too.....(he has big springtime volume and sell out strains every year then)...

I believ the reaso they don't smell is because you have no daily terpenes when you test them. Most evaporate above 75F and almost all above 90f which is about what your canopy temp is at. I've tested and proved this by running many different canopy temps and it's what determines smell.
You can actually run higher temps for greatest strength and yield and the just lower canopy to a max of 75 for the last week and all your terpenes will be there for harvest

they didn't smell because of the specific terpene profile that particular strain had, some strains just have little terpene ratios because of genetics hence the little to no "smell"... "no daily terpenes?"-- even if the prior exuded terps evaporated due to "high temps", new terps are exuded 24/7 to replace those lost due to the plant's "transpiration" mechanism
----"almost all above 90f" , really? then how do outdoor grows with canopy temps exceeding 90f get harvested and tested with the same (or higher) amounts of terpenes in-regards to air-conditioned indoor grows?? hhhmm, weird

well acording to rm3 and his site GOOD cannabis dosnt have a smell at all, unless you touch or make them throw off scents.Or.

I' am just simply providing another angle concerning what was stated, I also subscribe to what RM3 has stated on his personal site, would love to get a copy of his book to add to my cannabis library-- since most info online is really anecdotal based, all we can do is experiment/test things out for ourselves-- and go on sites like these and share our results.. Until cannabis is in full legal standing, being examined-probed-lab'd-peer reviewed by actual academics/scientist/botanist/Phds-etc etc day in and day out "in-regards to all grow data concerning this plant".. All we got to go on is the opinions, personal anecdotal info, experiments done by hard working & dedicated cannabis growers.. hope that garbled nonsense made sense hahaha

I did, after reading and exploring spectrums, lamps, PAR to death. So a challenge to all - has any one ever grown cannabis from start to finish with a regular HPS?
I have...... My avatar is one such example of "extreme success".
Glad my plants can't read.
