it all comes down to cost, I'd love to run two 6's as opposed to one 1K but then I would have to buy two more ballasts as well as another hood and two bulbs ( which is around 400$!!) Now that dual ballast is sweet, but it only runs on 240v, yet another cost....
better spread because the shape im lighting is a 7foot long aeroflo2 system not a square tray, the edges always suffer because the plants in the center stretch more further blocking lights from the 8 or so plants on the ends.
500watts is what I heard, wouldl it then extend the life of the 600w bulb since its not being run at full power? Wouldnt you be able to get more llight this way since you could get the two 500w lights closer to the canopy as oposed to the 1000w? Arent two points of light better than one since...
*when i said check the top, I mean on your water heater there should be a lil wide cone shaped flange connected to a vent which then is cemented to your chimney.
I did this, it was tricky though! You can but what you must remember is that you now pressurize the chimney by adding your ventilation. What happened to me was my water heater gas was coming back out of the top, you can check the opening with a lighter to see if air is being sucked in or blowing...
So who has used a splitter to convert their 1k hps ballast to power two 600w mh. They sell splitters at the grow shop, buy mh bulbs that have a differnt ignition (pulse start I think they said) add another hood and you have just spread your lumens over two points instead of one, right?
stay away from grow shops when buying soil, you pay too much and get too little. Instead go to a nursery of a landscaping center, buy peat based soil ( which what most of the shit they sell you at a hydro store is ) and amend it with a dry fertilizer of your choice, i would use happy frog, good...
