    Will this light work?

    If you can easily cool your flowering area than go for it - those lights are going to give you a loooot of heat (ballast plus light right above your plants) - but in most grow situations these would be too hot.

    Thoughts Comments and Advice Wanted - Nirvana Blackjacks 5 weeks flower - first grow

    Look for a small light source entering (or worse inside) the grow space from the closest side to your slower plant.

    I HATE running out of bud.

    check out riddleme's balls to wall grow and other threads and maybe you could grow your nut of weed with a 400 watt ceramic metal halide.

    First Time Grower 3 1/2 weeks W/pics, Let me know what you think!

    You want cfl's to be two to three inches from the plants at all times - meaning you have to move them every day to keep them at the right distance. Try to have a bulb for each cola during flowering if you want them turn out well. Edit - other than light distance causing a little stretching you...

    Balls to the Wall grow, Riddleme Gets Serious

    Here's the arcane info, unverified but sounds logical, as to why hps par watts deliver more useable light than an equivalent number of mh par watts: . Again, it's just info that would support your infrared theory even if the growth is just equal to a 600 watt hps.

    Thats a wild watt/par watt ratio - is the cmh particularly cool in temp?

    Newbie ? - why grow?

    If you have a medical card and money is not an issue, then it's a simple question of whether it's the type of hobby you'd enjoy. Never thought I would as in attempts to grow other things I had a brown thumb, but the lure of producing superior smoke and the sense of accomplishment when achieved...

    Balls to the Wall grow, Riddleme Gets Serious

    Ah, the light bulb has finally come on, so to speak. FYI - based on limited data, in my research in lighting for cutting edge wavelength specific info a 600 watt hps puts out something like 200 PAR watts while a 400 watt mh(no cmh but reason to believe it has similar PAR watts) has about 150...

    Balls to the Wall grow, Riddleme Gets Serious

    Wouldnt you expect a 600 watt hps light to out perform a broad spectrum 400 watt light in flowering, all other things equal? Even if the cmh was better on a per watt basis it's probably not going to overcome a 33% deficit in power, no?

    simple temperature question

    You want the thermometer Under the light at the top of the plant canopy, but shaded from direct light. If you let the light hit the thermometer you will be measuring the combination of radiant heat and air temp, and the air temperature guidelines are for air temp only. To get the right radiant...

    Myth busters - the real truth on CO2 in indoor grows

    Just an update on the experiment - between house guests and an empty vegging room the experiment is on hold until mid august/September. When I start back up I'm going to be using home brewer's suggestion of safe ale yeast to see if it can save some money compared to baker's yeast.

    simple temperature question

    FYI - you measure air temp with thermometer shaded from direct light, so your temps are probably actually lower than 79

    my medical grow room

    One warning - dual hose air conditioners take some room air and send it through the exhaust - I have no idea why - so you need to be concerned about possible smell issues.

    You just can't do that - as little as a minute of light can disturb the flowering process.

    I guess I'll just take this as fact and proceed accordingly. Troll.
