I want a PICTURE OF YOUR PLANT WITHIN 6 INCHES OF A BULB WITHOUT HEAT STRESS AS YOU CLAIM OVER AND OVER AGAIN BUT YOU CANNOT PROVE I WILL FOLLOW YOU AND TROLL YOU OFF THIS FUCKING SITE DUDE

OOOPS DIDNT ANSWER ME QUICK ENOUGH YOUR scared now. looking up answers on google! looking up plants you mean?

Looking for a picture of a nug next to a hps without serrations lifted up because its PERSPIRING TOO HARD CAUSE YOU SUCK.

So, is there anyone in here like me who actually uses the heat from the bulbs as a supplemental heat source?

I have a tiny veg cabinet with a 250W MH that stays on 24/7 and when it gets really cold I add a heat mat under the plants to keep them happy.

Of course I live in a fairly cold climate, and my cabinets are located in outbuildings on my property. I like the idea of running LED's but I've got this system dialed in over the past 12yrs or so and I'm scared I'd have to add more heat sources to the mix.

I added a 85 watt 5000K CFL and a shop light for heat....almost summer and 90 degrees outside yet with room closed off and vent from central air closed still have hard time getting to 85. I n winter I used 2 shop lights and added 102 watt 2700K cfl. Was able to take one shop light out (initially took both out but since put one back). My main lights are Rapid Led, Blurple, Kind flower bar (half price now).

looked into heaters but wattage would be about the same as the added lights. Like my temps between 85-90

Its not hard to rip pics of a 1000watt hps grows that will make those thirty look like royal dwarf strains. As said many times the king is the 1000w De, if peeps want to say cmh is better thats there bag but as to leds, pull the other one, most pics are of small fluffy buds that have very little depth.

Id rather be called a dumbass by led growers than back down to their stupidity, seven years and every year they have been wrong and had to change somthing because their yeilds didnt match those far out claims, idiots that just ruin it for the rest...!

Well, I don't have a horse in this fight but I can tell you that yield right there is the same as my last run with 2.2kw hps. So half the wattage, same yield (3lbs), I'm happy. Additionally I did not have the ceiling height for DE. Things to consider.

So I turned my air filter off and stress tested my room for 2 hours. humidity is slowly dropping but you get the point @Kingrow1, why would I put a HPS bulb in here , why would i try to argue that it would be good to put one in here? dont you think saving 400W in lighting to have it do better and 1200W of less AC running all summer? I'm saving 100 bucks a month. buying 2 complete 1000W double ended HPS all in one kits will run you 600 bucks + and extra 150 a month in electricity from ac and the lights compared to me. I paid 400 for my 8 100w qb boards and an extra 400 in drivers and aluminum and hardware. so I paid 200 dollars more than your newest HPS setup you can buy. and what . its gonna be paid back to me. in. like. A MONTH!??!


SO MUCH ENERGY SAVED THIS RUN IM LAUGHING ALL THE WAY TO THE BANK @Kingrow1

I'm sure he's just some troll shareholder in apollo horticulture or something. but I think that would be giving him too much credit.

Im merely average but one easily noticed thing is the better ive got theceasier it is to run hps cause use to be a point where it fried everything but now plants love it :-)

This is one of the pics he posted. If I had to be honest the buds look fluffed up because the ambient temps are too warm. Not saying they are ''airy'' but they look fluffed at-least to me.

Canopy temp partly. I'm in Autumn and my canopy temp is about 20C at this height, if I went higher my canopy temp would probably be less ideal.

I think the "blocks light distribution" is a moot point if we are in a reflective tent. I have pulled a pound from a single 600HPS in a 3.5 x 4 ft Scrog and as we know Scogs are all about the tops. I'm no expert and this was my first indoor run in like 25 or so years.

These are great pics to compare for you king. These buds look more healthy and dense because his ambient temp is likely in a more suitable range (all be it a little too cold). However you can see some actual heat stress on the upper leaves due to having the lights so close. If he had your ambiants and kept the lights that close I would not want to see the result, certainly would not smoke it even for free. Yes maybe their is some time between the two cycles but even with that in mind that's how the two growers results look to me.

Not that those buds are bad Lucky, they look very nice and dense considering your battle with temps.

Since king has not provided any evidence to advocate using hps within inches of plants I feel the need to warn new growers and yourself to never do it when you have your ambient temps in the correct zone. No good grower I have ever read up on keeps lights that close and except for extreme circumstances like luckys.. you will not like the results, trust me.

Root level temps in soil/coco are good at around 68-70F, slightly more or less is no need for concern. You ''can'' for the most part ignore canopy temps at that point becuase the lights when placed at the correct height will do the rest in terms of canopy temp. If you have good climate control you should be able to mostly sustain those root zone temps and mostly ignore canopy temps is what I mean. Instead you then read the plants leaves for heat curling.. move lights up accordingly.

Root temps >> Monitor leaves >> adjust height.

With 600W lighting 18inches is very good height.. resist being greedy thinking closer is better.

I can't say for sure on 400W but I'd personally start it at 14 and see how it goes.

On cmh 315w around 15-16inch is good, they are stronger than you might think. In a small 2x2 or so you may be able to push it closer but I'd be very careful of central heat stress. Those center leaves will yellow out and die off at around week 6/7.. to me that's not a good thing since it is truly avoidable stress. I would not personally want to smoke those surrounding buds.. but I'd definitely smoke the mid level buds directly below them ;p.

So unless king coughs up the proof links ignore him, it's very bad info till then.

That's why my flower light is a HPS. If I went LED for it id have to run a heater.
Its a juggle keeping the tent under 45C in summer but its manageable. My little veg tent is in the same room as the flower and cloning area so in summer I go from a 130w CFL to approx. 90w of LED (I think that's to much and will drop that down a strip for next summer so approx. 75 W. LED runs noticble cooler than the CFL. (lets W and not heating a gas)

Thank you mate, I grow in an uninsulated outbuilding (shed). So I just have to make do with what I have. Its not a large enough grow to consider AC. I'm in an illegal country.
They were grown over summer, so they had the odd 40c flowering temps.

Working with constant high temps under hps is doable but I've only ever seen it truly stand out once. It was a guy on these forums and he was getting high yield. He noted that his area had an unusually high co2 count and I personally assume that was one of the lucky factors for him. Most other people by all accounts would run into trouble with the summer temps he had (into the 90's if I recall).

90f is only 32c. I see hotter (as does most of Australia) in summer.

Funny how people from different climates acclimatize and find others extreme.

To me 30's C isn't swimming temps (unless the water is a nice mid 20's C)
Gets down to 12C and I'm freezing and not leaving the fire.

For my cold climate.
Even running hps @ $0.37kw/hr, is still cheaper than led. Just in heating cost alone.
This debate is so subjective.
