re: 250w CMH vs 250w HID

I'm very curious about that one too. Running both horizontally without glass. I wouldn't have to deal with the exposure as much as running a vertical comparison, but it would still tell us which bulb performs better, which should translate into which bulb performs better vertically also, I'd think, unless it doesn't ;).

Never thought about one light pushing out more trichomes than another... but Gator did! Might have to compare hash production too...

how about I keep the trim from each group separate and do two separate runs of bubble hash?

where the hell is that gaff? ;)

Actually, apical dominance is beneficial in terms of pollen capture and seed dispersal. Bending [or breaking] the primary tip allows for more vigorous 2ndary growth, and in my opinion, and more even distribution of the 2ndary bud heights, but this is a stress response and, in a natural environment, would result in a slight reduction of yield. In an artificial growspace however, we are constrained by the inverse square law and putting as much of our budsites in the sweetspot of illumination is more productive than letting the plants christmas tree naturally. I prefer LST to tip pinching or supercropping because I believe that the recovery period is eliminated [my plants straighten themselves out in a few hours and the lateral growth acceleration is noticeable by the next day]. It's actually a business 'decision' [let's not get teleological here] made in terms of evolutionary cost/benefit decisions that have been 'made' over the millenia, plant has it's own back, having 'learned' the hard way over time.

What do you think about the timing? I see LST as controlling the plant's energy into a shape that works for me, but is it a push to tie them down early in veg vs late in veg before the flip?

The downside to bending them over late is that you can break them if you're heavy-handed, but outside of that, do you see any significant benefits to one method vs the other?


I am supervising and coordinating two grows for a small medical collective but I don't have the option of growing at the SurfShak right now. Transportation and computer access are temporarily an issue, but I expect to live in the grow [or have it live with me] within a few months. I may do a journal when I have total access and control over the grow and easy access to a computer [my laptop finally died], but it wouldn't be very informative given my minimalistic technique.

SS i have a feeling this is going to be ur best grow yet from the way things are looking already. :bravo: those girls are packing on the resin, the best part is ur not adding any additives or special bloom nutes.
Click to expand...

I'm going to start using some hygrozyme, but at this point, I see no need for any bloom enhancers or any other supplements. The DM purple/OC+ combo is rockin', and the coco issues seem all sorted out, although I'm going to continue to give them a good flush every third watering or so.

I agree, this is looking like my best grow ever. I couldn't be happier with how things are going right now.


also you still do need ventilation with leds or any light, ur plants need the ventilation and fresh air. you just dont need as much because the goal isn't all about cooling down the lights like HID
Click to expand...

thank you for pointing that out Irish. You can't have a good environment without good ventilation, especially if you don't run CO2, which most of us don't, but the ventilation requirements for LED lights are lower, and you can use them in hotter weather than HID lights.


Yes, the LED costs more up front, but if I can get an extra grow or two in during the year, how much is that worth?


i agree i would pick the led tent if i had to choose also. dont get me wrong i would pick them all but i would prefer the led tent at this point and time
Click to expand...

it's going to be real interesting to watch things play out the next few weeks, and I'm hoping this grow helps answer a lot of our questions.

I feel good about the environments being as equal as I can get them, so it's all about the lights now.

Not till my last grow, which was a trial run with the GLH Spectra 360. That plant went 3.2oz, and I think these PPP ladies have a chance of matching that, even though they're more crowded. I only had two plants in that grow, and that one above on the scale was the bigger one.

Really good growers can consistently pull 4oz per plant indoors with the right strain and things dialed in.

I'm just a clown with half a clue ;).

Sounds good to me! I'd love to see what the difference would be between the two lights, and I'd imagine it'd translate just fine to vertical.
 
Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID

I topped some Sunset Kush and PPP clones, and I thought the difference in how they responded was interesting, and explains the radical lateral growth in my PPP ladies after LST. These two clones were topped at the same time.

The lack of vertical stretch in this grow in general seems mostly strain-related, so while the LED tent showed significantly less stretch, this may have been better demonstrated with a different strain.

Nirvana's PPP is a *great* indoor sativa strain!
 
Re: 420 Cannasumer Reports Competition - GrowLEDHydro 300w LED vs. 400w HID

I think you have a much better pheno of PPP than I do - my leaves look almost identical to my Strawberry Cough, where your's seems to have a bit more indica in there.

It did grow very quickly like yours is, but didn't fill in nearly as well.

Damn!

You're a gifted grower SS. They just look amazing! I'm always here lurking. This is a thread where I just shut up and learn. Not much for me to say.

Keep up the good work. Also, I really like the early frosting on some of those buds! Maybe someday I'll find a way to grow that strain!

re: the proper orientation for a rectangular hood.


It has to do with the shape of the beam. If you have a rectangular grow space and a rectangular hood, you want the long sides of the hood perpendicular to the long sides of the grow space, not parallel or aligned with them.

The light beam spread out wider in that axis, so your rectangular area would have better coverage if you have enough room to orient the hood in that direction.

Doesn't seem the intuitive way to set it up, but it works better that way.

How would you accomplish that with a Sunlight Supply Magnum XXXL in a Growlab GL80L?

sounds good.
its good that the OC+ helped out, might be a great mix for the colder temps, but not too sure in the hotter months? but seeing ur buds swell in real time is a good thing:bong: ive yet to see that, but if i smoke more i think i can.lol. ill trough some OC+ in my plants right now!

i am glade ur grow is working out good, ur plants look great and i think this will be ur best work yet!

i am going to mess around with the DM red a little bit on this grow to find a good combo to mix with it to add all the cal it needs and stuff. i have a few organic options i am thinking of, i am having a very hard time thinking of not using the DM red because the buds are so fat for me and very frosty. i dont think ill mess with OC+ this grow unless i need it to fix something. one thing that worries me is that the DM might not work as good in the lower temps as the OC+? maybe its best in high temps and OC+ is best in lower temps. i also wonder how the OC+ would do mixed with the DM red?

if you ever figure out the pond stuff make sure to let me know? i want to use it but way to chicken shit to test my math.lol. the hydro stuff ive heard great things about but it coast allot.
Click to expand...

I'm currently using the DM red supplemented with a bit of OC+. It's hard to tell yet how well they do together being my 3rd week in veg, and battling deficiencies for the last couple..but I have faith!

Just threw on some modular scrogs so hopefully can flip the 12/12 switch here soon and get a better idea how the DM red and OC+ do.

I'm real interested to find out a good combo for trfs/crfs that can just be watered and left to be..currently supplementing cal/mag, hygrozyme, and silica to my ladies.

Thanks for this link - very helpful. It looks like there have been some improvements on the How the Grow FAQ page - this link should be added to the list. Just a thought.

Again, thanks.

Do you know what the source of your PPP seeds was?

I'm keeping a couple of PPP moms with the same genetics as the ones in this grow, so if it's a unique pheno, I'll be in good shape.


Apparently, there is a more sativa-leaning pheno and a more indica-leaning pheno, so mine's most probably the latter.

I've got 8 fem seeds left, so I'll have to sprout a few more and see what turns up.

Are these techniques mutually exclusive?
Click to expand...

I guess not, I just haven't thought of all the options. It was a trip to see how easily and naturally these PPP took to the LST, but after topping the clones, it was obvious why they do well with it.


Here's what we do with the extra clones [the box I told you about] after the Autumnal Equinox, [mama nature's free flip],

That's just like what I was envisioning for a small multipurpose greenhouse. Thanks for posting the pic.

Was that Vicky next to the PPP clone?
Click to expand...

yep, that's Vicky. I'm replacing the original flowering clone moms with two new ones that I'll keep more bonsai-style, hopefully.

Vicky's future is secure for now.

It took me 11 World of Seeds Afgan Kush to find the pheno I wound up keeping. Since you are dealing with a 'stabilized hybrid', it probably won't be as easy to spot as the difference I found in a supposed landrace strain. Good luck. Been busy the last couple of months. Obviously you have too. Keep up the good work.
