Help choosing an LED replacement for 1000HPS?

[a mongo frog]

Almost 5 weeks of veg from clone under LED. I even whacked off a few lower branches to pot her deeper into her final pot,also did a major trim clean up before this pic,3x3 screen.

Looks great!!!

Vegged in a 3x3 with some other clones under 50 watts to start and 150 watts of LED at the end.

both it's legal here! But the recreational shit sucks and it's overpriced

Thank you Vantucky! We still are "waiting" for 7/01 but I don't mind the short drive across the river....

tired of long cocking we all can grow to the best that we can true facts some day i will own MCCOBI JUST PERSONALLY THINK best time to jump in them are in next 2 years just to much advances going on now as there hitting there peak but like everything else we need to watch the graphs or what ever advancements as to where the graph start pointing downward no different how i invest or sell buy low sell high in this case its kinda opposite wait on reults showing peak levels ??
How else can i say this technology slows down then its ran its course and tweeking it you get bit more does that make sense

about 25% at best....

Suddenly not so attractive. HID is 20% or so, only marginally better, if at all. I looked up some company that had 47% efficient bulbs that fit a regular e-29 ? socket, but they were $59 for a 13w bulb.

Also consider that if your amortization time with a 50% efficient flowering lamp is 5 years, the amortization time of the same lamp in veg would only be 2.5 years assuming you run 24/0 light cycle. Imo, when you get toward the point of 2.5 years amortization time, the question of financial value starts leaning heavily in favor of the 50% lamps. Sure, if there was going to be another lamp released tomorrow that was 60% efficient, I could see why you may feel like you've lost out on opportunity cost, but this is a gamblers mentality. You're speculating instead of producing. I want "a lamp that can produce", now.

A lot of people want to replace their flowering lamp with leds, but then do something silly like upgrade their MH to T5 for veg. A way better choice financially would be to keep HPS for flowering, and keep MH for veg, and smash up all their T5s. If you're going to replace MH in veg, replace it with LEDs. The upgrades people have been making to T5 have frequently been downgrades.

I find T5s to produce as much heat as an equivalent HID. Their efficiency is no greater than HID. Their form factor is better for small plants, tho.

Here's a plant from 2013 that I flowered with Cree household bulbs just to see what they could do,got around .9 GPW if I remember right.

I had so much trouble doing that (High temps with high RH). Maybe my temps weren't high enough, i was just so scared to run at 85 degrees. Co2 was such a learning curve for me. Many sleepless nights. At one point i had my phone alarm set for every 3 hours to go check the room.

Mongo you know me from long time ago i have ran temps near freezing near end of flowering talking 2 degrees cold, and from my experience running temps hotter 85 - 88 degrees it just took my

Mongo you have known me from long time ago, i have ran temps near freezing near end of flowering talking 2 degrees cold,
I follow more or less what mother nature does and thats make it rain in my room litterally and from my experience running temps hotter 85 - 88 degrees increased my photosynthesis. or optimal plant growth
You ever walk into a botanic Garden / green house ??? you walk in and almost stop dead lose your breath from the heat n humidity ....
and the plants in there are fucking phenomenal and why ?? higher temps and VPD
i used to follow the norm 76 degrees and it grew but once i said fuck this going to run it like family green houses and fuck me talking 4 - 6" growth daily you can literally watch it grow in front of your eyes ..
there is allot more at work then just spectrum root zone temps everything its amazing but growing with LED ot HPS you get all the more important shit taken care of then no matter what you use for lighting ..
Its going to produce i even run foggers in room da hell with foiler spraying plants like i said
make it rain lol .. here i figure i share, just love this pic with seedlings

Right now I'm running 80 degrees 900 ppm of co2. For me and the fire og its my sweet spot. I can't re think co2 again, it'll hurt my little pee brain. Fuck that was a nightmare......

stop babying them plants and bump everything up including temps try 85 and 1300 ppm for one week are you in veg ???/ or flower

It is the Q10 effect. For every 10c you rise in temp...the metabolic rate doubles. That is why co2 enriched does so well at high temps...the plants are metabolized faster and matching the increased co2 available. As well as keeping the rest of the variable up to the metabolism.
I'm still working on CO2 myself too. I do like 85+. Darth is right...the shit just grows big and fast.

I don't have the balls.

Im in my last week of flower.

 

[a mongo frog]

Sorry guys I'm sticking to 80 degrees with 900 ppm. And let me guess you want me to use this???? 300 bucks down the drain.

When I go over 80f canopy temp I notice the flavors and frosting change in my favorite cuttings (for the worse). The SSSDH takes an extra week or two to finish with those conditions and even then not a clean finish (some mature trichs but some immature calyxs and pistils) and the buds are looser.

According the the PPFD/temp chart rate of photosynthesis increase by 20-25% by boosting your temps from 77f to 86f. But does that translate to 25% more medicine? I suspect not, especially when you factor in the slower finishing time. My 2 cents anyway..


Ace of Spades 10 weeks high temp grow, 47g


Same cutting 8 weeks mid temp grow, 53g ea

Mongo last week of flower ??? shut the c02 off already
i shut it all off 2 - 2.5 weeks before harvest and slowly lower temps and light hrs i usually start week 5 11 hrs on 13 off week 6 10 hrs on 14 off my last week 9 on 15 off same time droppin temps to final week 65 degrees in room

Its been off for 2 weeks. Hopefully soon!!!! Come help chop. Ill fly you in as long as you don't try and fuck my wife!!!!

Single ended HPS is technically out-dated now. Doesn't change the fact that it's still a solid performer.

people act like the lamp is going to stop working if it 'goes out of date' so to speak. Terrible line of thinking.

lol Mongo but i will give you deal on a room controller 350 bucks for 3 year old iponic 600 that is like brand new cloud server ready and programed and wrapped in box like the day it landed here ... let me no haha you pay or shipping its yours was mounted away from any grow room like brand new in mint shape
