Just build your own custom setup, dont use a pre-fab commercial product You can build it to suit your needs and space perfectly, and save a heap of money

good information with reference links, well presented nice

do most strains stop stretching when they hit 2 weeks into flower?

I dont think a light mover is what you need for your situation, I think you need to focus on cooling with upgrading your ventilation setup I dont think you have the level of engineering skill to build your own light mover from scrap parts... its not an easy task Personally I just move the...

I have a lot of extension cords running between balasts and timers and fans, all neatly secured to the rails on the roof that also support the lights I have a small desk that holds all the power boards and timers and each power lead is labeled so i know where it goes Everything is tied up with...

I have a 400W MH for veg, and ill put seedlings under it as well, but keep them further from the light until they get established If you have them too close it can roast em

gas tanker is correct again... and as far as bringing low wattage lights closer to the plants and thinking it will give them as much light as a 1000W, your dreamin the 1000 would shine right thru many layers of leaves, feeding them all more photons than they can lap up, the lower wattage has...

LST it! Tie that bitch down or scrog it...

as legal flying said... you suck air in from your bedroom thru a duct - light 1 - thru a duct - light 2 - thru a duct - outside thats your lights cooled now you need a completly seperate ventilation system for your actually grow room, put the CF inside the flower room, suck air into the CF -...

mirrors are a bad idea for grow rooms... they reflect all the heat, and focus it in to hot spots look at the best professionally built reflectors, they always have dimpled shapes to disperse the light read up on it, theres plenty of info on the net about reflectivity of light and heat...

It dosnt matter if its solid dirt, ground water will seep in if its more than a couple feet down To make it worth while, the hole in the ground would need to be big enough that you could walk into it, so your not just taking the lid off a hole in the ground and trying to reach down 4 feet to...

take 12 clones, and keep the best 8 for veg I always make the mistake of growing too many plants and once they are bigger they are choking each other out fighting for space and light, and restricting airflow as well as making a nice environment for pests and mold less plants dosnt always =...

why dosnt anyone use those proper light hangers, you just lift the light or lower it and it holds it at that height automatically chains are a pain in the ass to adjust all the time ofcourse this idea would still work with those light hangers if you wanted to move the light around, which you...

so when his 16 clones are ready to veg... theres only room for 8 of them in the veg area does he just pick the best 8 and cull the rest?

as long as the gaps dont create light leaks, they should help with air flow, as long as you have good ventilation setup they will be passive air intakes make sure you disinfect that mofo and line it with plastic sheeting inside make sure your electrical circuit can handle all them 1000Ws...

the hole in the ground would cave in, as well as fill with water if its too deep you would have to build all the walls out of concrete or brick bit sus your neighbours see you lifting a trap door in your garden to access it, and as you open it all this bright ass light beams out of the hole...

difference between cfls and mh is the node spacing under cfls they stretch up trying to get more light i would get a cool tube for your mh tho in a tight area

I disagree with the 'try it for yourself and work out what works for you' approach... there are hunderds of people with a much deeper knowledge on these things than us, and we should learn from their experiences and advice. Other wise every new grower has to start from the beginning again and...

more watts = more growth getting a lower wattage MH is not going to speed up your veg, MH of the same wattage will shorten node spacing making shorter bushier plants If you wanted to speed growth up you would run the 400HPS AND a 400MH at the same time more watts = more growth

Its more important that you have warm air getting removed from the room, than that you have fresh air comming in... dont dump the warm air from your lights back in your room I would try to have a passive intake to another room in the house if you can, not from the freezing cold outside...
