I think the most important part of growing your own is to keep it only for you nobody has to know about it or you will be in trouble, even with friends, friends tell other friends and so on, it has to be top secret.
Good joke 40 thats the best grow op i ever seen on the second pic the guy that made that set up is a genius unfourtunally they got busted, it was an impresive underground cave in tennessee what a shame.
If it wouldnt be so damn hot in my grow room i would get the 400 watt too, im having high temperature problems sometimes 94 degrees so the 400 would be the dead.
Im thinking to buy the same ballast pretty soon i guess it would the job i have a scrog with 3 clones under a bubbler sys and they are almost ready to put them under the hps. how many plants do you have if less than 6 you will be fine.
Mine has 4 spots and a 5 gallon res, i cant afford a tri meter so i change the res solution every 2 weeks so far works fine but the hot temperatures are starting to mess everything i guess i should get a water chiller, you got a great deal on your sys. so enjoy.
This technique is very easy and worked for me: buy some rockwool cubes and root hormone to make some clones put them in a clear plastic cover, drill some holes on it, to keep the humidity as high as possible spray the cover and clones with water several times a day for 2 or 3 weeks then there...
I think you should invest in better nutes from other companies such as advance nutrients i have been using both vegetative and bloom the final product wasnt that bad but i think you should check this video YouTube - Nutrient Challenge it makes change my mind about general hydroponic i hope this...
