No flowering is counted from the first day you put your plants on the 12/12 cycle. You should start seeing sex around day 12-14 depending on strain.

Invest in HID. You can grow with the T12 flouro but your not going to get the type of yield that you will get using metal halide and HPS. Its simple science. Look at your PAR ratings for your lights and compare. PAR is the amount of correct light/radiation that your plants get in the...

also if your box is wooden &doesnt have to be stealthy consider having a hole cut to fit the size of the lite so that it sits on top. that will give you back the height of the light because its not taking up space inside the cab.

okay let me give u the easiest answers. for lighting spend 10 bucks and go to home depot and pick up the basic wiring manual. the easiest explanation is take a bathroom fixture, the kind that has severa bulbs that goes over the top of a mirror and take an extension cord (2 prong) cut the female...

i would go with a dwc system. no pumps or nozzles to have to tinker with. can ga large or small. easy to maintain. you can youtube dwc for videos.

it really all comes down to how much you wanna spend. i ran cfls as a newbie i got good smoke but, again, nothing compares to the chunky buds u get with hps. an hps 400w will give you about 55000 lumens. you would need 35 - 23w cfls to equal the light output. thats 805 watts. Hps will always...

looks good, but dude, you have 388 watts of lights and your probably pulling what maybe 18000 lumens from these you should invest in an hps an pick up a 400 hps and get 50k in lumens and big chunky buds at the end. its worth it man. i went both ways with cfls and watching the buds fill out at...

yeah lower lights change water once every 7-10 days. next time use cfl or normal floro for seedlings. superthrive will help build your network of roots quickly and then they will take off. I never put them under hid until they have a good root system going. Also they are right should always...

pretty. I think you shoulda scrogged them tho. That plant looks perfect for it.

The correct answers would be to have a seperate room for flower and veg so you can run ur C02 when and where you want . Also keep the pump near the cool air spot or it willraise the temps in your res. Stop overthinking it use ur C02 and experiment with it. Do some research on the internet for...

The lighting delay timer is a good idea, albeit check at an online or local grow store you can get them pretty cheap there. If you've got 130.00 to spare invest in a UPS backup. Since your outages are short you should have no problem supplying up to 500 watts of power for a while and then you...

1st of all is that 1000 parts per mil.? You need to up that to about 3000 ppm if you want to see real growth. Normal air supplies 1500ppm so you are actually supplying less than the air around them. also what type of c02 are you using i.e natural or bottled.

looks like a light / nute combo prob. The leaves are turning up and brown which could be heat or nutes. Need to know the strength of the nutrients and the water schedule. When they start turning in like that could be not enough h20 but the browning on the edges suggest nute burn. more info...

ok dude here is the old school of thought. you need a minimum of 3ooo lumens per square foot. so if your growing in a 2'x3' boxthats 6 square feet you need 18000 lumens. That doesnt even begin to get scientific with the PAR of your lights and what have you. go with the 3000 lumens (or a...

I ran cfl during my first grows. Used the 42 watters that kick out 2800 lumens. They were good. 6 plants 2.5 oz. Now I run a 400 w hps setup 4 plants 6-8 oz. I was running 10 42 watt cfls thats 420 watts and and only 28,000 lumens. With my 400 hps i get 50K lumens and 130 PAR. Hid is just...

i dont understand, why dont you just switch to a lower wattage hps or MH instead of the flouro. Flouro dont give you as much light penetration as your HID light plus is it 2 4ft flouros with 4 tubes or 2 tubes?

okay a couple of things for those who want to give more lite during flower you can go to a longer day period as long as you still have a night over 12 your fine. It doew give certain strains a noticeable difference. I did a 16 on 16 off and i did see marked improvement in how she filled out...

i have and lemme tell ya it sux. i learned to be very strict with the light regimen. dont stress your flowering plants bud.

its doable but understand that the bottom of your mom will not really be getting any light penetration with t12 fixtures. What you can do since its a perpetual vegging mom i assum is crop her down to 2 or 2 1/2 feet and put her under your other flouro until u can get some more lights. She wont...

ppms only 350? Running a little lite you think?
