250w HPS Club And Help Guide

LST seems to be going well enough. I cracked a branch, but put it right back in place and I expect it to heal (and form a nice knuckle) within a few days.


I've considered another change to my grow box. Now that I have two fans installed, it has crossed my mind that I could upgrade to a higher wattage bulb if I connect my four inch fan to my hood, which has been designed to receive a four inch flange on any face.

This would leave my more than capable six inch fan to circulate air while the 4 inch fan is pulling directly from the hood.

One thing I wonder, however, is whether my space is too small to justify a larger light, be it a 400w or 600w. Will a more powerful bulb produce a sufficiently positive marginal rate of return relative to the increased cost of purchasing and operating that bulb?

Put another way, given my small cabinet size, will buying a larger bulb make the price I pay per unit for marijuana go up?

Damn dude you got almost every auxin routing technique in your grow lol.

A 400 will bump the heat up substantially as well as cost more in electricity so..... yes it will make it cost more per unit/gram. Also get those cords off the ground, that's just asking for trouble.

If you're going to upgrade, make sure to get dryer ducting and duct/vent the air through your hood. So inside the cab it should go like this Carbon filter>ducting>hood>ducting>fan>exhaust. This will dedicate cooling/venting of your biggest heat source, which is your light. If you choose you can add more ventilation to the cab solely but you will need another carbon filter. This is a passive intake system.

Joos you should ask Racerboy my journal partner, he went from 250 to 400. You can post in our journal, my invite went out to everyone in the 250 club and even if people aren't from the 250 club I don't care. Everyone's welcome =]. I know Racer has to keep his AC (window) on 24/7, I leave mine on 24/7 but the cooling turns on and off. Not sure if his is on cool 24/7 or what, you'd have to ask him. He's a great person, and one of my closest friends these days on and off the forums.

Just figured I'd add a link to my Journal here.. first Journal attempt. This is my 4th Grow and I have 2 plants in the Journal. One is a Nirvana Blue Mystic (fem) and the other I am calling Mystical Mutant is from my last grow of Blue Mystic that I took to seed.
I think I know now why the last grow went to seed, I had a huge heat problem and didn't know any better.. I let the cab get into the mid to upper 90's when I was 6 weeks into flower. This will not happen again..

Lol yeah even with all the knowledge/experience I have, I still stumble on something new here and there still. It's an art and art is not very easily mastered, if even achievable.

Glad you worked that out Grazz, and always feel free to hit me up with a question or for more clarification buddy =].

Posted these in the Journal and figured some of the 250 Club might like..

Welcome to the club Strange.

CFL's you have to change out every grow to get best results, they go quick. Feel free to ask any questions and share your pics, can't wait to see what you got growing =].

Just noticed an aroma escaping the room. Huh, 5 weeks into Veg and I had to turn on the CF, just when I got the temps perfect..lol.

Lol Grazz I feel your pain, I was planning on switching to bloom but.... I need to switch out the old carbon with some new carbon. My gals are in veg too and whooo man they're stiiiiinky already. Came back home yesterday and yeah smelled all the way down the hallway lol. Sucks because they're so ready to switch, going to get the clone tent set up tonight. 2 tents, 1 closet man it's gonna be cramped lol.

Doob,
My plants have been growing terrifically, and I am still at less than 1/2 strength nutes,(I took some pics but left the camera in the room, I'll post them later) I may be looking at them too much but when I noticed the tips on some of the older leaves with just a tiny bit of browning I didn't want to bump the nutes at all. I figure if they are still growing like they are they must be happy.
I will be switching to bloom in the next few days also, just trying to be sure I have the light from my cloning/mother area blocked off. That was a question I had for you.. Does it really need to be absolutely dark?

Oh yeah, I "think" temps won't be as much of an issue when I switch over to the 250 HPS from the 400 MH. Of course when I get some "New" CFL's for fill-in I will surely have to fiddle with it again.

10 and a half weeks flowering. She close to the chop?

GPC,
How do the tricomes look? Can't really tell from the pics but if your not flushing you might want to start soon.

Grazz

Cracked and hanging by a thread, now healing toward a full recovery.

Its hard to tell. My jewelers loupe is tiny. Ill try and get a good look at the trichomes when i turn the lights on, And I started flushing early, thinking the grow would finish sooner then it did. Ive been flushing for about 2-3 weeks now. Think theyll be ready for the chop this weekend?

Kinda quiet Doob..

I personally keep it dark dark dark, but if you do have a little light like around moonlight output then you should be fine.

Temps will hermie a plant because of the high stress it puts on the plant. Glad you worked that out though Grazz.

Very close to chop, look how much prettier she looks now!! Look at your trichs when the plant is not under the HPS. The HPS will give out false ambers sometimes. That'll tell you best, but personally she looks good to be chopped at 11 or 12. 12 would be better, your pistils are more receded in the calyxes now. Great job GPC!!

Figured you were working on the CF and getting set up.. got the plants under HPS starting today. Temps with the 250 HPS have settled at about 76-77*F..
Dark: Was thinking of maybe picking up some Panda film but then I remembered that I had some old window shades (the roll-up kind from back in my school days) that I had snagged when they put aluminium blinds in at work. They are real thick and I checked last night after lights out in the cab and it's absolutely dark..
Posted some pics on my Journal..

Sweet dude, like what roman style shades?

Even older, the kind that was on the spring loaded wooden roller.. back in my school days they would pull the blinds and turn off the lights when it was too hot.
AC? We don' need no stinkin'AC!!
