They can use lower wattage because you leave the lights on for 20-24 hours, so the amount of photons striking the canopy on a given day ends up being the same, just spread out over a longer period of time, if that makes sense. It's called the DLI or Daily Light Integral, and what the plant...

150W won't replace 400W of hps, but is a more appropriate size for 5-6 sq ft. If you are seriously concerned about summer heat, you could try running autoflowers during summer. You'd only need 75-100W for that space.

I've built two cob lights, and done a DIY kit from HLG. The HLG kit takes about 10 minutes, the cob lights take a day or two. You need to build a frame, drill holes, figure out your fasteners, it's a whole thing, and much more involved. I'd do a QB kit in a heartbeat if I were in your shoes...

LEDs are taking over every segment of the lighting market, and continue to get more efficient with every update cycle. Everything else is the walking dead at this point.

The only "fan boys" around here are the people jumping into every thread in the LED section trolling people with their bullshit about other lighting tech. Meanwhile LEDs have already won the war, but some people's brains are too fossilized to ever admit it. Boring wet blankets, insulting...

The best part about autos indoors is the ability run much lower wattages, which means cheaper more efficient lighting that runs cooler. Let's say you normally need 150W to cover an area, now you only need ~90W if you are running a 20/4 cycle. Talking about grams per watt is sillier than usual...

Again, one good reason is DLI. Photos can't take a 20-24 hour day, which means lights running at half the wattage to get the same amount of photons down on the canopy. Autos can be grown with like 60W of LED a plant and still hit 3-4oz per in 60-80 days. That's completely nuts. With a photo...

If you can afford better, get better. There are some CFL die-hards around here, but being real every other light source is better, and in a space that small it's not very expensive to step up to something more suitable. Three plants is a lot in a 2x2 area, and unless they are autos you won't be...

Well solution #1 is to flip now, not a week from now. And I'm not trying to be a jerk, but 4 plants will not work in there at that size, trellis or not, lighting change or not. Which is what everybody keeps trying to tell you. They are going to explode. If it was me I'd keep 2, do a real...

Because you should have been flipping topped or well-tied plants a couple weeks ago. Those have outgrown the box. Honestly even 12/12 straight out of the gate would have been too much with that many plants...have any room outdoors?

You said 157W per square foot is good for early veg, and then told him to double it? High or joking, I still can't tell. Anywho.

Dude you have like -2 weeks left in veg.

Can't tell if you are joking or doing math while high. I'm OK with that.

The act of forcing another person to fund somebody else's ideas is called living in a society. As a matter of fact "funds" themselves and the means to transact in them is paid for by, you guessed it, tax dollars. So enjoy bartering, I guess. And only traveling on roads you built with your own...

The problem isn't taxes, although that's apparently your pet issue, it's how they are spent. The US spends more tax dollars per person on healthcare than any country in the world. That's a fact. Do we have the best universal healthcare in the world? No, we have sick and dying people who can't...

Wow how did you find a 7 year old thread to resurrect...impressive!

What is "the other day", and what did you transplant them into? Some of that looks like nutrient issues, some of it like nutrient burn, which sounds like a hot soil and PH problems. Most deficiencies are not deficiencies.

So far nobody has named a better seedbank than Seedsman. True North is over priced and their shipping is $lol on top of it. My last order with Seedsman I ordered 10 seeds and got 20 freebies. All 10 popped. They also got to me in 4-5 days in the US from UK. Now I sound like a shill. Oh well...

You know, I ignored autos for many years, got some free dinafem genetics in a seed order, threw them outside and holy shit. Autos are potent, high yielding, and stable, at least from the right breeders. People underestimate how quickly humans can shape plants over a few quick generations. They...

Sour hounds are small and dense in every grow I've seen online. I have a couple freebies I was thinking of making seeds from, and doing a SOG. I think they would be perfect for a dense, even canopy.
