i really don't think the turn on time (and off time) for a hps light is going to affect your crop and certainly adding 5 minutes of dark isnt going to rectify any problem. You have to remember that these are plants, not machines. Machines expect certain peramiters to be fulfilled on time and...

i think the reference you just read was in reference to electronic(digital) ballasts. perhaps wikipedia? "Electronic ballasts alter the flow of electricity in the light bulb by using a series of induction coils that are separated from one another. In contrast, magnetic ballast uses 1 induction...

almost all digis do. the An Baddass ballast is a low freq digital. Magnetic ballasts are all (to my knowledge all) low frequency. and ps, your sig. I just looked at some different purchases from a dispencary. Know what i found? all clear as glass trichs, maybe one or two cloudy, and a lot of...

What lights do you have? Make sure your ph is good and you don't overwater, looks good though, some are just late and slow.

Thanks for the fan find. Can the speed be reduced with a standard speed controller?

A old tech 400w magnetic will pull about 500 watts to power that 400 bulb. They are pretty inefficient. Keep in mind magnetic ballasts are designed to output their power at a very low frequency, and most bulbs designed today are still designed for a low frequency arc. Digital ballasts send out a...

Don't kid about the seeds. Some people get touchy. Plant choice will be important as your room is your limiting factor. How big is the case? I would add one or two more cfls in there, more the better. Just watch the heat though. Get a thermometer that records your high temps, most important...

Wow that's something I have never seen. How many seeds has this worked on?

UnLess, like stated, bad breeder/genetics. Too much destabilization in the bloodline

It's not a bad learning step.. You can get some expience for later when you have more room and better genetics. Lots of people grow some great bud in pcs. Only an ounce or so though. Have you considered a speaker box? Not entirely out of place if you have a computer.

i have a 3x4 (12sq ft) area and 4 bushes (not even that big) would take up more than their fair share. i would go about 3-4 bushes and lst them for some good yields. would take a bit added veg time, but not a lot. thats one more benefit of small single cola plants, you get to clone and 12/12...

it really comes down to coverage. If you have enough t5 lights on top and sides you can get the equivalent of hps penetration. but once you add all those lights together the heat and electricity can surpass a ventilated hps system. don't be afraid of the heat a hps system puts off. 400w and...

Gonna be a good rig. Kinda scares me. That size op is intimidating. How hard is that insulation foam stuff to cut and trim? i need to insulate my basement but the opening is only about 3x3 and i cant fit a 4 ft wide sheet of plywood at an angle, so i need to trim.

Thanks for the good words. i got home yesterday which put it at about 5 days since watering. two of the plants were dry as were their water globes. the last was dry and the water was still in the globe hah, that particular plant has some real crap soil, so it probably clogged upon insertion...

i was thinking a simple expansion chamber would be sufficient considering the lower volume actually going through, but you don't want to risk the valve freezing open, that could be bad. Some tanks can be opened and the siphon tube removed, unless its a welded top. some tanks also have the...

t5s can produce so can cfls. its just how much you have if you add up all the watts it takes a whole lot to get hps level of lumens. the reason the glh lights are somewhat expensive is because they work. if you go through all the off brand chinese led units your going to be very disappointed...

haha nice :P

the correct answer is not soon enough :p

well there seems to be some confusion here. an ac unit should only be treating the sealed air, it shouldnt remove any air at all. you need to rig it so the room side of the ac is inside your tent and the window side is on the outside. Depending on your regions relative humidity the part outside...

wow what a self inflating douche haha. "mine is better and im pro status, look i got my name on my head, sooo pro" seriously grow up. Its not the system that makes the grow, its the person behind it. My first grow with a rainforest 66("professional" system, aero, $$, etc) was total and complete...
