Which would produce more DO in a DWC?

    I was wondering this last night as I was in each tote last night to pull out roots that were traveling and looped them around the main mass to help keep it there. I remembered your post about it so perfect timing!

    So the verdict is directly under? I was looking at one of the totes and I thought maybe the airstone was acting up cause it was so low, picked up the plant and it was boiling again. So in my head no surface agitation = less DO but your experiment has proved the opposite?

    I haven't done any extensive testing, but from the little I've seen, I'd say directly under the netpots/root ball is better. When you think about it, getting DO to the center of the roots is the challenge. So spreading the roots out, from the force of bubbles, seems like it solves the issue. I'd imagine that a powerful pump is needed, to create the massive amount of bubbles necessary, to force the center of the roots to spread out, and ultimately grow like that.

    I was also theorizing that the spread of the roots may be determining how wide the leaves and branches grow. From what I understand, the perimeter of the branches, of many plants and trees, is the same as the roots. So if the roots are spread out more, then maybe that's the way the plants are responding. The roots for the WW in front (the smaller one), were hanging straight down. Once I put the stone back, and the roots spread way out, the plant grew wider. Now, it could also be that providing more bubbles to the roots is resulting in the sudden increase in width, and not the spread of the roots.

    Stepping up my game...

    I've decided to upgrade to a 1000w ballast and lights. I'm not getting enough spread with the 600w. The footprint for a 600w is really 3x3, and with my netpots being in a static position, I'm not able to bring plants closer to the center. I'm much more interested in potency than yield. I've got plenty of room left on my fans, and I have to check my temps to make sure they haven't dropped into the low 70's.

    The ballast I got on ebay was only $73, and was one of the most popular ballasts. I also got an iPower MH and HPS. I was contemplating sticking with the 600w, and getting Eye Hortilux lamps, to provide more intensity. But I realized that the best 600w bulb doesn't come close to a basic 1k. In total, it was only $120. I did some computer work yesterday, which covered it, so it was basically free :)

    I'm still keeping my 600w ballast in place, because I can swap plugs with the 1000w ballast, which will be mounted next to the 600w, during early veg when I don't need as much light. This is better than dimming. FWIU, dimming lessens the life of the lamp.

    This is why tonight I will be working on somehow attaching wood dowels or something to each corner of each lid and then getting a trellis net over each so I can train each one towards the centre which has been largely underutilized until the last few days as they stretch a bit more now. My first 3 are monsters and 17 inches, hoping to cut it down to 12 with net. Having on each bucket gives me more flexibility.

    Having shade around the sides, and especially in the corners, has really been bugging me. Last grow I was supplimenting the lights, with CFLs in the corners, and it was a mess, with all the cords. It worked pretty good, but was only a temporary solution. They added heat to my tent, and raised the temps 5 degrees.

    I think my White Widow are using performance enhancing drugs!

    I had forgotten that the White Widows rooted at least a week before the others. It was really quick, and their roots exploded. So, the others are catching up, but it'll be interesting to see if they get to the same size as the WW.

    I got my 1kw ballast set up today! Huge difference! I've got great coverage now! Believe it or not, the temps barely budged! This is the advantage of keeping your reflector hood air isolated from the grow area. I've only got my 6" fan for the hood, and the 4" fan for the tent exhaust, at between low and medium. Last summer I grew indoors, and my house AC didn't run any more than usual. Of course, not everyone wants to cut a six-inch hole in their subfloor LOL! That's only for the brave...and those who know how to reverse it back to normal :) I probably wouldn't have moved up to the 1000 watt if I didn't have the hood isolated. I'd hate to be sucking out all the conditioned air in my house trying to keep it cool!

    My new, unimpressive ballast next to my old, unimpressive ballast. They seem to grow the weed, so I'm fine with them. The way I have them makes it easy to switch back over to the 600w, for early veg when less light is needed, or as a backup.

    After adding the 1000w, the huge fan leaves grew by inches, in just a few hours!

    I had to spread them out:

    That WW is pumping some weight! You've probably answered it, does WW just grow this fast? Or are these autos?

    If you like that for your next upgrade try de .

    My 750 gavita replaced 1430 w so far .

    But you need high ceilings 8ft at the bare min .

    Still awaiting the final results though:)

    I am going to swap out the tent and probably rebuild the room its in right now to a grow space in the summer, I would be just under 8ft, I would still get good light/sq ft? whats the footprint? can it be run in a sealed hood or tube?

    If you wanted max light id say 4x6 is the foot print.

    But mine doesnt have a problem lighting up a 8x8 (7.5x7.5)

    And my canopy is 7.5x6ish lol

    Ill have to double check my bulb height tomorrow but i guess its 7.5 to 8 ft up and my net is 3ft off the ground

    I'm not sure if the WW just grows like that, but I imagine the strain has something to do with the size. I don't grow autos.

    I'm going to be trimming some of those fans back today. They're blocking a lot of the older growth.

    DE lights are meant to be run in the open. They work better when they're hot, from what I understand. I've been wanting a Gativa, but don't have the headroom.

    On the money JSBB

    De bulbs need to hit a certain tempuratures or else they dont preform (weird right).

    But this doesnt mean they run super hot or anything.

    As in i dont notice my fan coming on more with this light then my old light.

    But i grew in a 5x5x5 box for many years
    And loved my 1k digi in an aircooled hood :)

    Like adding nos to a car lol


    But you do need headroom
    I havent gotten too brave about lowering my light as close as i can lol dont wana bleach them bitches :)

    Yeah, I think I'd want a Gorilla with both extensions, making it 9' tall. Or, just doing an open grow. But that presents its own problems to work around.

    For sure .

    I was a pro when i moved out of the basment. Having it dialed in for many years

    Went back to noob status when i went above ground lol

    Like total opposite problems ha ha.

    But its so nice to have a room i dont have to be hunched over in lol my back has never felt better :) its funny i think

    My room still isnt the way i want it but its getting closer

    Your stuff is always good jsbb i wish i knew about weed forums when i first started but it was still illegal 15 years ago lol

    Haircut day! These are so bushy that the circulation is lacking in the center. Also some condensation on some leaves that were laying on top of others. Trimming was overdue, but they were so bushy that I didn't know where I was going to start, so I kept putting it off LOL!

    Topped and trimmed. They look kind of ugly now, but they'll fill out again fairly soon. I don't know if I'm going to top again, or just supercrop.
