gah, the wat/lumen thing is kinda confusing to me.

Are those sites safe to buy from? and have them difrectly shipped to my house? Or will it be intercepted or w.e
like i've been reading about seeds/mj


would i be good with these?

for everything

http://www.1000bulbs.com/150-Watt-Me...t-Bulbs/34139/ - 1 of these

http://www.1000bulbs.com/70-Watt-HPS/999/ - 1 of these

http://www.1000bulbs.com/3-Way-CFL/1559/ - 2 of these


with all of these bulbs i'll be using a reflector.


thanks in advance

yes they are safe, your just buying lightbulbs, thats not illegal. & no those bulbs wont work, b/c metal halide & high pressure soduim bulbs need ballast to power them, they dont work in a regular bulb fixture. each bulb has a wattage, lumen output, & color (kelvins). since your growing steath id stay away from the hid lights, but just in case heres a good one http://www.htgsupply.com/viewproduct...roductID=48631, & this is what youll need if useing cfl http://www.1000bulbs.com/2-to-200-Wa...n-Light-Bulbs/ any of these that arev 26w+. or look into some t5ho flouros http://www.htgsupply.com/growlightty...categoryID=107, when u do get bulbs youll need 6500k for veg, & 2700k for flower. read this http://forum.grasscity.com/general-i...cfl-guide.html

I know ventatation fans run 24/7 but is there any time like during lights off when reg. circ. fans should be turned to a lower speed or off other than during the day w/CO2?

Hey, got another quick question about humidity. For vegging the humidity should be 60%+, what are the bad effects if it isn't that high? My plant has been out of the mud for almost 2 weeks and I've never had the proper humidity, 90% of the time my meter says low so its under 20%. After watering it will rise to 35% for a very brief time. I have a bowl of water in the box with a fan on it, another bowl of water with perlite in it and I can mist but it doesn't seem to do anything.

I'm wondering if I should continue to fight to rise the RH or if the plant will do ok with 20% RH?

unless your temps are high, turn them off, i do, b/c mj plants dont & cant use co2 in dark.

yes, i used a 26w 10.0 uvb bulb last grow, & i noticed a difference, & i had mine on only during flowering for 12hrs, but play w/ the hrs on, to see the best results, some say 5-6hrs, & the strain will play a role too. just go to a pet store to get some.

looks as though it was flowering, u need to put it back on 24/0 light to reveg her, & it should grow to a nice plant.

Do they do anything with the o2 when they sleep?

green plants give off o2 & take in co2, part of the process of photosynthesis.

thanks alot. i think im getting it now. all i'll need is a ballast + bulbs with the right wattage/lumens and i'll be good to go correct?

http://www.htgsupply.com/growlightty...categoryID=107
can i just get this and be good to go? i mean i'll be using these for vegg and flowering. so i can just switch them out.

correct me if i'm wrong but there are 3 stages: germination, vegetiation, and Flowering


CFL's work in regular bulb fixture?


Oh yeah, and one of my seeds have a crack in them now. so that is a good sign =)
