are my 2 40 watt fluorescent cool white tubes gonna be enough to just barely make it through the whole cycle? lol I know I'm a cheap skate. the space is like 3 feet deep by about 7 feet wide and about 7 feet tall...good enough?

HydroSan

aim for 50w psf of HID lighing. a wide spectrum HPS like the Son T+ would be best.

your 80w of flouros will make a great cloning light, but a very poor growing light and will be completely inadequate for growing in that space.

but would it help if I added another 80w of the same thing I already have? and do they even make hps or hid bulbs for the fixture I already have? I doubt it but even so the people in here said fluoros would work for growing anyways

yeah, fluros will work but you will need more of them. your best bet is to do like hydroSan said and go for an HPS. you can get a 150 watter at lowes for under 100 bucks or you can buy off ebay and find a great deal ( i just picked up a 250 hps for 80 shipped)
again though, you can use fluros. harvest will suffer in quality and quantity but you can stil have a harvest. I use the CF's with better results then the tubes though and you can get more of them in a tight spot

lowes has an hps?? damn..I hope that it comes with a ballast lol but for now, you know, I am going to use a fluoro and save up my money for my second grow and get an hps system, but they're so damn bright!!! lol

newbie777

would I need two more 40 watt fluoros then?

justawannabe

how do you mean- do they even make hps or hid bulbs for the fixture I already have?
do you have an HID fixture already? if so then yeah. If not and you just wanna put it in a normal socket then no
will the extra 80 watts help? sure it will help. may even be enough light for one plant to go into flower but wouldnt try it on 2

newbie777

well I think I will get the other fluoro lights for an extra 80 w...hell they're only 20 bucks for the whole thing lol and then I'll start saving for an hps, but for right now fluoro is the way to go for me

hey man a good thing to do is maybe buy a few 4 foot long bulbs like 8 thats what im doin 2 on each fixture for 4 fixtures you can use this all the way till flowering and about the 40 days later you should buy a hps they work really good for flowering how all goes well happy growin

You know the saying it takes money to make money? Well it takes money to make bud. Basically your pissing in the wind with the flour's. I tried it years ago with 8 48" fixtures fitted with two grow lights each (not cool white) and about all it produced was some tall, spindly, mostly male plants with a few females with a few flowers here and there with no bud to speak of! You would be better off with a couple $30 envirolights or a cheap HPS from HD or lowes.
