Spectral comparison of a CMH vs a HPS.
View attachment 2211508
Those Phillips Retro Whites only go to 400 watt right?

Here's a quote from another board..
"The ceramic halide conversion bulb is rated at 34,800 initial and 29,600 approx. mean lumens, but a cheap ($32.00) plain old HPS has 50,000 initial lumens and a nice Hortilux bulb designed for plants has 55,000 initial lumens. Also, the Hortilux is listed as having a color temp of 2100K, and the ceramic is 4000K, which is something to consider. Basically, the bulb is a conversion bulb for better looking lighting in warehouses, and conversion bulbs are always less efficient than dedicated bulb/ballast combos, plus metal halides are unnecessary anyway what with modern HPS bulbs being so well designed I'd say use it then sell it and get a digital ballast and a bulb designed for horticulture."

Sorry but more red = more bud is not true. Red is actually the least needed part of the spectrum. It also puts out more heat and more wasted energy. Hps vs. Cmh is like brute force vs. Pinpoint precision. People use lumens, watts per square foot, etc. Plants don't see lumens. You should measure photosynthetically active radiation, which is the light that can be used by the plant against the light that just bounces off.

But yes they currently only go up to 400 watt. And when comparing a 400 w to a 1000w there's obviously a huge difference in output. Cmh also put out uvb and operate a few degrees lower temp. I believe using both hps and mh is the best until cmh make bigger systems.

Just got on.

I dunno y I can't access the market.. Like an error pops out? Maybe it's cuz I registered but I never ordered.. I was waiting for some bodhi to drop like today lol does anyone know what dsb stand for?
Yea six was okay but 4 and 5 were, eh meh.
Wasn't too into the whole Mexican cartel shit, i think it drifted too far from WEED, WEED should be the plot of a show called weeds. Not mexican cartels and slutty moms.
Yeah I couldn't agree more lol.. Too much drama and not enough growing

pretty interesting. thanks for the info.

i ran 24/0 MH when i started out, now i run 18/4 MH, and i definitely rarely get a male anymore....just thought it was my bad luck..

just got 8 female, 2 male, and 2 no sprouts off of 24/0 mh..... with strains and breeders, there cant be a perfect way.. just my imo

yea spectrum is most definitely important when it comes to seedling stage thru the first month.. that and light schedule. 24/0 will always give ya more males, 18/6 with a MH bulb overhead, you'll have so many gals you won't know what to do with em all. i remember reading all this before and saying.."eh whatever." and then 5-6 weeks later it was like getting bitchslapped by my plants when I saw all those balls.
interesting! but doesnt genetics play a strong role? isnt a seed predetermined to be male or female?
Jorge made me buy one of these things today..lol I say Jorge made me so I can blame him later if I don't like it

I have a few of these the 10 gal are the best and anything under 5 is a pain to water they just run off or come out the wholes, but they so grow nice plants!

Let mine go ten then chopped. Grew in 3 gal buckets hydro. After the 8th week they went into a growth boost and started to turn purple here and there. Exceptional yield of frosty beautiful buds
yea they do turn purple if you let them sit, Im on week 8 now and they are yellowing if I dont feed them enough its def a heavy feeder!

great high too. Like a good stop at a light, no jerk or anything. Just a smooth come down that wasn't even noticeable at least not to me. Something I would always like to have in the yard
yes I agree an I like how it kills my appetite or doesnt cause the munchies

I always wanted to try it.. but now I realize there's no need. Bodhi's Apollo 11 f3 has an amazing pineapple smell. Big thank you to the dude that made it possible for me to have this cut.. ohh and to Bodhi too.

I'm finding it hard to keep it yellow tho thru bloom. I've given it teas, and fish emulsion.. last night I actually foliar fed her with foxfarm growbig. Anyone out there ;) have any input on her nutrient requirements? I don't wanna overdo the N or Mg. I'm only at day 34. Shes taken all the nutes I've given and I keep bumping up her feed. Damn plant likes to eat.

I find these PE start yellowing to if not fed enough I feel like im gna over feed Im using dyna grow at 2tsp a gall or 10 ml, 1.25 ml mag pro, and 2ml pro tekt and a couple plants are still showing yellow leaves

whats the best haze strain out there?
Mango haze or super silver haze from MNS I hear.
But Neville may change that ....

You need a magnetic ballast for the CMH.
But it has a cri of like 91 the best available I think.
Very close to sunlight.

My blue Hortilux hps wont even fire up unless I thump it.
The blue spectrum is provided by a mini blue bulb in a standard hps bulb an is a joke.
A MH an HPS combo is alot better IMO.

You should measure photosynthetically active radiation, which is the light that can be used by the plant against the light that just bounces off.
Photosynthesis relies principally on a large amount of energy absorbed from the high end of the visible light spectrum. In this respect, it is the most important portion of the light spectrum to plant life The red-light-wavelength energy absorbed by the plant cells combines with carbon dioxide and water to manufacture simple plants sugars in mesophyll cells that are embedded near the top and bottom surface layers of leaves and, in a few plants, the green stalks or stems as well. The more red light energy applied to the chloroplast cells the more intensely and quickly those cells carry out photosynthesis.

So in a way, more red does = more bud. As long as your light penetration is there too. It goes without saying you need bright light.

So of course light penetration is important. But spectrum easily just as important. I have gone a whole cycle on MH before. The buds midway thru the canopy were more airy and yield was less for sure. There's not a single person who can convince me MH is better for flower and if that was true so many of us would allready be doing it. The red spectrum the sun emits in late summer months is what you should be trying to produce.. like I said before tho, if you can add blue spectrum light as well, youre certainly better off.. but most will not.

Bodhi germination

Sunshine daydream 4 for 4
Dream Lotus 2 for 4 :(
A11xA13 3 for 4
Cali Yo 4 for 4

still have hope the dream lotus will crack some more only been 24hr so far

These IHF2 are ROBUST! I only have them in 3 Gallon pots and am now thinking that was a horrible choice lol, having to water damn near every day even with letting run off collect in the drip pans. Also the clones are already out growing the KegCups !?! aggressive much?

#5 is a very very big leaf slow to start lady I have probably cut the shade leafs anywhere from 2-4 times now.... no bud sight formation as of yet


#3 is a little slimmer on the leaf size and has bud site formation developing


have no clue how many times I have super cropped the tops but, it's a lot... standing tall the next morning every time...strong like bull

My GTH#8 that I was sure was going to be male is a female. This thing blew everything in my garden away on growth during veg, will see what kind of bud it produces. I would of lost a lot of money if I had bet on the sex of this thing. I literally cut it in half about 2 weeks in to keep my canopy even.
