What kind of ballast is running that 1500 wt mh and how much and where would one acquire one? Also, the little round(5gal?) bucket inside the dome, is that for monitoring the solution? Man, another impressive build. Always giving me new things to consider
hey buddy! thank you!

the bucket is there for monitoring and adding,
D9 must admit looks wicked TBH really like it curious on what you used was it 1x3 hard wood possibly 2x4 for base curious really looks great
person could purchase a decent tent octagon style pretty cheap ???

I'm guessing not. Sorry for the pestering. scaling it down (allot) could work for me but, I guess, I'm jealous. Good work, thanks.
Hey D9 curious why you decided for 1500 watt MH ???
Dam that things must just pump out the heat what about efficiency on them ??? its been years since i grew with a MH that shit should be in museums lol.. i dropped MH after few grows and never looked back way that room looks not sure on size but man oh man couple
E paps inbetween DE's would kick ass

I find the use of platonic solids other than a cube quite intriguing. An octohedron may be a better way to do a 4 plant, 5 light X grow.

WOW! D9 has taken this to yet another new level, with the shape of the space being integrated into the lighting plan. VERY nice! The design goal is five plants, each producing... ?? What size is the space? I may have missed it above.
I've been wrestling with the portability problem. Instead of doing any veg in my bloom spaces, I've opted to build a series of spaces optimized for various veg stages. This helps smooth out the perpetual nature of my operation and allows for many efficiencies.
I chose RDWC became one can pull an entire plant up by the netpot and the hanging roots come right along. The water lets go like no other media can. If I were to go with a PPK as it's been discussed here, I'd have to move the base and media as well- and it's a lot bigger and heavier than the half empty 8" netpot bucket lids I'm using now.
The rest of the merits of the PPK system are so compelling that I'd really like to try it for my next build- especially if said build is in a remote location I won't be able to check every day.
The alternative is to continue using my RDWC, but throw a ton of automation at it. That's expensive and creates more failure points. While there are some advantages to RDWC- if this can match the output for less inputs then the engineer in me says it's gotta be worth a hard look.
Soooooo... I'm back to trying to figure out how to make a PPK system mobile?

Dollies exist for both muck buckets and 3.5/5/6/7 gallon buckets.
Suppose you have a lower part of the plant module on a dolly or casters.
Remove top in veg area, set into mobile unit, move, place into new lower module.

hey, doc! this first one is really overbuilt and cost more than it could have but it was still only around 1100 for an airtight, extremely reflective tent encompassing around 110 sq ft.
light will go nuts in there. in the photos above the only illumination is a 55 watt cfl. absolutely no other light. i'll try to get a pic with all the lights on at once. it's blinding anywhere you look.
the bulb itself comes with uva and uvb warnings. hps bulbs, no matter what they are, have very little to no uv and are weak on blue, even the dedicated ag bulbs.
i've just read some research that states unequivocally that uvb especially, in drug type cultivars as opposed to fiber types, increases thc but not cbd. i'll see if i can find a link.
UV-B RADIATION EFFECTS ON PHOTOSYNTHESIS,
GROWTH AND CANNABINOID PRODUCTION OF TWO
Cannabis sativa CHEMOTYPES

(Received 29 August 1986; accepted 24 February 1987)
Abstract-The effects of UV-B radiation on photosynthesis, growth and cannabinoid production of
two greenhouse-grown C. sativa chemotypes (drug and fiber) were assessed. Terminal meristems of
vegetative and reproductive tissues were irradiated for 40 days at a daily dose of 0, 6.7 or 13.4 kJ
m-* biologically effective UV-B radiation. Infrared gas analysis was used to measure the physiological
response of mature leaves, whereas gas-liquid chromatography was used to determine the concentration
of cannabinoids in leaf and floral tissue.
There were no significant physiological or morphological differences among UV-B treatments in
either drug- or fiber-type plants. The concentration of A'-tetrahydrocannabinol (A"-THC), but not of
other cannabinoids, in both leaf and floral tissues increased with UV-B dose in drug-type plants. None
of the cannabinoids in fiber-type plants were affected by UV-B radiation.
The increased levels of A'-THC in leaves after irradiation may account for the physiological and
morphological tolerance to UV-B radiation in the drug-type plants. However, fiber plants showed no
comparable change in the level of cannabidiol (a cannabinoid with UV-B absorptive characteristics
similar to A' THC). Thus the contribution of cannabinoids as selective UV-B filters in C . sutivu is equivocal
"Only the AY-THC
content in leaf and floral tissues of drug-type plants
increased significantly with UV-B radiation.
Regression analyses indicated that there was a sig-
nificant linear increase in A'-THC with UV-B dose
in these tissues (Fig. 3). The concentration of A"-
T H C in leaf tissue increased by 22% and 48% with
a total daily UV-B dose of 6.7 and 13.4 effective kJ
m-*, respectively, as compared to controls. The
same levels of UV-B radiation resulted in a 15%
and 32% increase in A'-THC, respectively, in floral
tissues."
there's more to the paper. it's easy to find, and free.
i hope the additional blue light will not only contribute significantly to basic photosynthesis but also function as a morphological shaping tool. i want short, fat, heavy plants.
i used the stromberg plates as connectors. they are $90 for a set of 11, which is enough to build one. the first you see here is 2x4's but it is way too strong for a simple reflectix tent. the second one is 2x2's. the first one i stapled to the inside of the frame. and then put a piece of 6mil visqeen over that. for the second one i won't reflectix either the floor or the ceiling. only the ten triangles around the sides. this cuts the reflectix to 4 rolls for this size and far less tape as i will staple it over the outside of the frame greatly reducing the amount of tape needed to seal it. the ceiling on the second one is a piece of 10 mil white plastic tarp. i will great stuff foam the frame to the floor creating a good seal.
after this second one i won't build any more this shape because i want more headroom over the plants for DE fixtures. i might turn these into propagation and veg rooms. it depends on the final word on recreational plant counts. we are 6 months away from submitting license applications here.
i think one also has to be aware UVB also fucks up plants cells and breaks up DNA like human cancers same shit can apply to plants some UVB is ok but to much is not good either ...
Reason i got rid of mh is i was getting same results with HPS tight nodes compact plants ..
also from doing some reading people tend to think of color spectrum as one of the most important things but truth is
that light quality is much less important than light quantity. While light quality will govern certain aspects of plant metabolism, it has a small effect on photosynthesis, which is the most important driving factor in plant development. While this goes against what many LED grow light manufacturers and the crazed spectrum growers have to say about their products and the wavelengths they put out but, the fact remains that HPS lights are still the workhorse of the indoor cannabis industry, and for good reason.

hey! i ran a perpetual with the flower room in 12/12 fulltime. a few feet away i had an eight foot foam hexagon with six sites for vegging. i would simply pick up the top container and walk into the flowering room and set it in place. that's it.
but a 7gal tub with 5 gal of wet turface is about 70 lbs so now that i have lumbar stenosis i will either have help or use a dolly. also using a wave pulse you can use other, lighter materials. i know i can grow big plants with perlite perhaps amended with a little coco fiber, like 5% or so. pumice has 1/2 the bulk density of turface, and you can grow completely in coco. i have grown some nice plants in straight coco.
i hope to get 2 each from this setup, maybe a little more, we'll see.
this one is approx 110 sq ft.
but if you need to transport in a vehicle between your vegging and flowering areas just get some of these same totes with holes in the lids. like sockets. i can put six 3 ft diameter plants in a standard full size van.
i'm hoping i won't be in the "fucked up" zone. i totally agree on using hps for "throw weight". but this particular mh bulb is a 4000k with a strong spike at 600nm so i think it's going to grow well as well as shape the plant better. there is a lot to be said for "brute force" and nothing delivers that yet like hps bulbs (for the money). i will have 5 very efficient ones (600's) in there as well as the mh with the same approx whole array luminous efficiency as 5 1k horti's at a higher electrical efficiency.
these new de bulbs are too good to ignore but can only be used horizontally. but i think that's just for the bulb. so what if we took a fixture and attached it to the wall or something with the fixture turned sideways but only rotating the bulb around it's horizontal axis thus maintaining it horizontally but projecting fully to the sides. considering the footprint of the de fixtures even though the bulb is off axis in relation to the plant it would still bomb it.
or the de's above and mh's dropped between the plants for large vertical plants
if you look at gavitas literature they state that the hps fixtures, if used without sunlight, as in indoors, should be supplemented with their lep fixture to accomplish a full spectrum. i think they are correct but damn that thing is overpriced. i looked at it's spectral output and it pretty much matches a good mh or cmh bulb. or the right leds or flo's.
so what i think i'm getting to is the combination of de's and mh's for commercial use.
if they remove plant count restrictions growing large vertical plants will become economically non feasible because of the veg requirements.
then i think we are going to see a lot of 25 plants to a 5x5 with a de over it and some supplemental blue of some type with uvb. low to no veg time, root em and flip em.
When you guys say a 3.5 in a 5 or a 2 in a 3.5 do you mean that they fit into each other and still have enough room for air gap or is there a lid on the bottom one and then you just put the smaller bucket on top?
I'm looking for something either 1 gallon or 2 gallon top and running 4 plants in a 2x4 area. I'm planning on vegging for about a month or maybe less.

There is a lid on the bottom one. For ex. a 3.5 gallon bucket with recessed lid sits right at 10.5", so if u built a 6" drain on the top bucket, would give u 4.5" from drain to bottom of the bottom bucket. So if u set the water level at 6.5" in the bottom bucket, u would have a 4" air gap between the water level n bottom of top bucket.
we are saying bucket on a bucket, not bucket in a bucket.

I am playing around with ideas for changing up my vegging sites. Currently it is 6 1qt containers on top of one of those 27gal black totes w/ yellow lid. I was using fabric wick, but I am finding that I am having issues with the media not draining well, and the fabric wicks get pretty nasty looking. I am considering trying out a 3/4" media wick somehow. My current idea is to use grommets in the bottom of the 1qt containers, then slide in 3/4" PVC and perforate it quite a bit, both below and above where it enters the 1qt container. I will try a prototype tonight and post some pics, but was wondering if anyone else is doing or has seen miniature PPKs with media wicks. thanks
