its just common sence, HIDs are what the pros use, cfls are for amateurs, if u got the money get a HPS, a 250w wont make the electricity bill anymore higher than a good cfl would. and dont listen to the people sayin hps isnt good for veg, i veg under hps and it works just fine for me.
You Can. It's just not practical. You'd end up spending more cash by setting up ventilation, The initial cost of the hps, bills, and seeds than the amount of weed you'd get off the plant. You'd come out cheaper just buying weed. Remember he's only growing one plant.
If you don't have heat issues and funding issues, CFL's shouldn't have a place in the grow room other than side lighting.. I have seen what and HPS does during vegging and I have seen what CFL's do, not much of a difference imo.. You wanna go all out get a CMH for vegging ^^
Lmao thats ridiculous.. HPS won't burn down a house jesus -.-.. A huge portion of the active members here all use HPS' anyone burned down a house yet? That is what I thought.
Agreed. Complete rubbish.lol...... lol..........
I am was making a bit of a generalisation. Thats the way Australians spell it before i get the usual spelling quotes. HPS and CFLs dont create nearly the same heat. There are too many people here banging on about using HID which shits me. I have always agreed that HID perform better but also that people fucking around with HPS or MH and not knowing how to properly vent them will end up in tears. So much advice on using them with so little advice on the conditions.
I understand that heat may be an issue, so excuse me for sounding like a douche because I do realize that HPS create a high amount of heat. However, you may be right, some people may be retarded enough for such a thing to happen. But believe me I have used an HPS with NO ventilation other than an oscilating fan (still only a 150 watt HPS with that) and not had issues. Of course if you let your temps get ridiculous there is that possibility always, but not that a plant would be able to survive in those heats.
Maybe you should have stopped there as you don't need to hit me with PM's and spam this thread. I PM'd you back and told you I didn't mean anything negative to you by what I was saying. And no I realize that a lot of growers do reach dangerous temps. That comes with the territory of growing. I chimed in with the LITTLE experience I have had since starting growing and using a low wattage HPS. And yes I PM'd you a thread with a few pictures of my plant in there. I am no grow master nor do I claim to be. Just thought I would chime into this thread on what I do have knowledge on, which would be starting a first grow and getting through it. WITH AN HPS.
I never said it did it. My original question was if I had two 250w CFLs running 15,000 lumens each or just one 250w HPS running 30,000 then what would be the difference if there both using the same lumens, why should I bother investing in the HPS which will cost me hundreds more?? People are saying that a HPS would better because of light penetration but surely iof you placed the 250 CFLs close to the plant then light penetration would be exactly the same.
Because you are running 500 watts opposed to the 250 watts from the HPS. And by running 2 250 watt CFL's it wont double the lumens just the coverage. Which will still help your grow a lot obviously but google it. The science is the light penetration is better. That should help to make your decision but google and look for it if you want the actual science behind it.

Read some of this thread, might not give exact science behind it but the theory of why light penetration is important is in there: https://www.rollitup.org/grow-room-design-setup/172913-cfl-vs-hps-penetration.html
