I recently found this "200 watt CFL grow light system" for very cheap but i emailed the owner and he said that the thatlight consumes 42 watts but puts out an equivelant of a 200 watt bulb. Would it be worth it to buy this light. is it 42 watts or 200? it was 54$ american before tax and shipping. thanks.
I could be mistaken but I'm pretty sure thats just another way of calling it a 42 watt CFL. The cfl only takes 42 watts but it puts out the same amount of light as a normal 200 watt bulb. The rule of thumb I go by is at least 75 watts per Sqaure foot. So for example if you had a sqaure foot of grow area you would need two of those lights. You would have 84 total watts. The watts their equal to doesn't matter. And I just bought a 42 watt CFL the other day, myself, and I only payed $9.95 for it.
Not worth it. It's just like a 11W CFL that says it's a 60W equivilant. When using CFLs, you measure using the actual wattage, not the equivilant. And since 28W CFLs are only $5, you could spend $10 and get just as much light.
Yea thats what i thought, it comes with a power cord and reflector. alright. ANd one more question. would four 30 watt tube flourecents and one 70 watt hps grow one or two plants.
4x30 + 70 = 190W You could grow a couple plants with that. But if I were you, I'd just bump it up to a 250W HPS and forget the flouros.
