agreed!!!!!too small for nine plants...unless ur doing them in solo cups.. i'd go with 4 or 600hps.. I would do 3 with that 250.. save the other 6 in veg take clones... by the time u have enough money to get that 400 u'll have at least 12 clones ready to flower... do a sog
Ok, i was planning to grow them in single pots and the actual area covered by the pots is something like 2.1X2.1 thus giving me 56,7W per feet, but since i was erecting the grow area i wanted to plan for future(600W hps) and a grow area of 3x5 and 24 plants.on average 30 watts per square foot is the least you would really want and you are at about 16.6 watts per square foot. Not ideal conditions to grow in but you can still grow something for your efforts if you choose your type of grow wisely. I would build or find a smaller area to grow in, to concentrate all the lumens of your 250 on a SCROG or perpetual SOG depending on your growing medium. Smaller HID's are an interesting challenge that can surprise you with a decent yield if used efficiently.
Ok, cut the space in half then, ok..... but why ?if you really want to make a wall, then make just one so you have 3 x 2.5 grow area and that in return gets you 33.3 watts per square foot and makes batter use of your lumen output.
Ok, cut the space in half then, ok..... but why ?
Is it to maximize gain from reflection ?
That´s the only gain i can see between a smaller and a bigger space using the same lamp. But like i said, im a NewBee in this and probaly something im not thinking of
Again i wonder, cut my space in half so i get a better number from the equationFrom what I've read you would ideally want at least three thousand lumens per square foot. I took a piece of 3/4" plywood cut it in half and put casters on the bottom. I then took two by fours cut them off at six feet and used the other two foot of wood for feet of the movable walls I built. I took a piece of masonite cut it in half and attached the two pieces to the six foot two by fours to make my walls. I have the front of my grow open so my window air conditioner can blow into the opening. Here are a couple of pics. I started ten plants, I'm hoping for six or more females. I also left the bottom of my movable walls open. My containers are at least a foot tall so I didn't need any reflection low, plus I wanted to leave the bottoms open for ventilation.
