I switched from a 4ft 4bulb, much better for me. I switched early tho so they were only a few weeks old, but much easier to deal with space, and its actually cooler being I have much more room for airflow.
Dont have to worry about only having 3" of effective light, also if you have good airflow and cooling they can get pretty close to a 250W bulb, mine have been as close as 4" at times without burning.
With a fan blowing between the bulb and canopy I have my 250w 4-7 inches from my canopy. Thats with avg air temps 93+ in my grow box. I know people say to take temp at the canopy but I find cannabis can handle much higher radiant heat from the bulbs so my gauge is at canopy height shaded from the direct light. Just have lots of ventilation and air movement and push the limits of how close you can get.

I go by overall temps inside the box too.

If I stick my thermometer under the light it will hit 88 - 90, anywhere else inside its 77/82.
From what I read they stop, or slow growth after 85, so I dont see that happening. My temps have not changed, and if they are slowed in growing thats a good thing, cause I'd be out of room lol...

The two pics I posted were taken 21 days apart from what my folders show..

my new 250w hps setup that i upgraded from a T5 2 footer so im expecting good things this harvest. Any tips from grower vets are much appreciated!View attachment 2266048View attachment 2266049
I would turn that fan horizontal and drop your hood down some. Start at 9 inches or so from the canopy, have that fan blow between the hood and canopy and monitor the plants frequently till you find that "goldilocks" zone. I have my light about 5 inches from my canopy with no bleaching or other issues. Had I not had so many overall temperature issues I would have run my cfls too.

Thanks for the speedy reply! I made the adjustments as per your recommendations and the temp actually went down a little bit so thanks for the help =)

cbt, how do you always have so many plants going all the time? You hit us up with a non-stop assault of pictures of wonderful flowers and I love to see them, but assuming your growing with a 250w light, how the hell do you do it? The pic 15 willie nelson plant looks like it is 2 feet tall and 2 feet wide. That's half a 250's foot print all on it's own.

haha i was just thinking about that.my boy has same 250w as me and i get 2-3X as many harvest.well training has some to do w it. my grow footprint is about 40"x 22".and i just started a new idea i leave my 250w on 17hrs a day and use 2 30w cfl for other 7hrs.then have 2 sets of flowering plants.a little extra work but yeild nice and often.i dont even know if that made any sense im blown right now.

Perfect.

Let me know what you think of the results, I will probably pick up a bottle of the liquid.
I used liquid koolbloom but not the floralicious with just the regular flora line of gh nutes. I did use florablend off of a recommendation from a friend whos swears by it for hempys. I think the koolbloom had a noticeable effect on the fullness and density of the buds. I also flushed with clearex every 7-10 days which helped alot compared to not using a flushing agent on my 1st grow.

I think that's it. my sis does cell and fiber installs, I have quite a few rolls of the stuff
Hell ya dude! We never call it string, the old timers wouldn't have any of that, always cord. Have her get you a pair of the bad ass datacom scissors, you can't really trim with them but you'll be hard pressed to find a better pair for any of your needs.

My father is always hitting me up for lacing cord, I had to show him how to 'sew' a little bit with it as well, starting stitch to finish....

Idk what it's called, but i use it for fishing and crabbing.
If it's covered in wax then it's lacing cord, it's probably 9 ply if it is. It used to be 12 ply, hence the outdated name of '12 cord'. It's used to 'sew' cables down to cable racking and down the sides of equipment. There's various stitches one can use, like a running stitch or chicago stitch. When sewing fiber optic cable some telco standards define you to use paper over the fiber cable as to not damage the glass. This cord is strong and will cut open your hand if you sew for long enough.

Kushberry update and more crappy pics :sad: I really need a new camera.
11 weeks from seed, 8 weeks flowering, just started flushing with distilled water a few days ago.

The buds just keep climbing, as you can see the largest tops are getting dangerously close to the light but I think it will be fine for 1 more week. That's the great thing about 250w lights, the tops can get pretty damn close without doing any damage to the plants.

1-1.5 weeks and I think they will be ready, what do you think?

Post a pic of the scissors.. I'm in the process of stacking all of her left-overs from jobs in a corner and she has 4-5 tool bags.

I personally like the extended handle for what I do, makes it a bit quicker. I use my normal handled pair around the house, my wife loves 'em too.
