DIY 1200watt Under Current with DJ Short Bluberry, Sweet Island Skunk, Sour Diesel

Here is my DIY under current system using mostly home depot parts.

Each system consists of:
2x 600w Galaxy Digital Ballasts (Had from previous grow)
5x 5gallon buckets w/ lids
4x 2gallon buckets no lids
6ft 2" pvc
4x 2" pvc elbows
2" pvc T
2" x 3/4" pvc bushing
3x 3/4"x 3/4" pvc barbed hose attachment
3x 3/4" barbed elbows
495gph inline pump
7' 3/4" flexible hosing
Silicon aquarium glue
Reflectix
2" Uniseals (only part I couldn't get at home depot)

Here's what the room looks like during the leak test stage. You can see what
the system looks like when not recovered in reflectix. If anyone has any details
on how to construct feel free to PM me, but it's super easy.

Nice setup dude! Do you have 2 chillers in there? or is one an A/C

2 Chillers, and an AC.

Left system is a blueberry strain which should take around 9 weeks.
The right system is sour D (up to 13 weeks) and a Sweet Island
Skunk (up to 12 weeks). I want to be able to flush my buds for finish
so I am running the systems individually. I can scale the system to be
as big or small as I wanted as long as all the plants in the system
are finishing around the same time.

Dam you have a nice set up ...2 chillers and a AC nice.. On the AC is it a 2 duct exhaust or one duct .. Mine is a 9,000 BTU single exhaust . How do you vent it ?

The ac is a single duct exhaust. I run the exhaust line into the next
room. Other than that the room is sealed. Leaves me with 78* while
lights are on and about 70 when lights are off. Well see how winter
changes those things though.

I have a similar set up its a sealed room too. I run mine outside I came up with a DIY trick to rid of odors . I just basically filled a nylon full off activated carbon and shoved it in the duct.

I'd love to exhaust/intake air from outside, especially with the Colorado weather.
The neighborhood here is just very tight knit and they're all developing families
with 2/3 young kids each. The houses are all about 15 feet or so apart and with
kids constantly running around outside I'd really have to be on top of my smell game.
We already stand out as the 26 year old couple with no kids in the 4 bedroom house,
and I'd rather not have the HOA down our asses about a medical grow in their
neighborhood.

Ha I'm about the same age just a couple years older and I live in a Suburban neighborhood too real family orientated but I'm a single bachelor .. +Rep to you dude nice set up.

Thanks!

Going to try something new this grow, gonna try some Greenleaf Nutrients to see
how they do. I have usually been using advanced with good results and came
across these nutes for about half the price.

Tonight is day number 35 and I will flush them overnight with some florakleen and
switch the lights/nutes tomorrow. Should hopefully be some nice and frosty trees
for xmas. I have also turned the chiller temp down to 61*, I have heard 58 was
a good place to be, but I'm nervous to go that low and don't wanna spend extra
electricity powering chillers to constantly be putting out sub 60* temps. So far
the girls seem to be loving it. Also added some great white to the mix.

I wish there was more to post, but this system is just so simple the only problem
I have right now is lack of calcium/magnesium due to using RO water, but that will
be fixed tomorrow.

Starting up flowering today and gave the girls their flowering
food consisting of:

Advanced Sensi A/B
DM Zone/Silica
Greenleaf Bloom Blood/Bud Explosion/Cal Mag Bloom/Sweet Candy
Great White
Hygrozyme

Day 1 Flower (Day 37):
PH - 5.8 PPM - 700 Res Temp - 61*F
RH - 30% Ambient temp - 78*

Looks like a sick setup. I'm interested in getting a real UC but I'd like to check your results. Chillers a must with these water systems huh?

I don't think the chillers are a must at all, I just wanted to use
them for the extra DO since my air pumps are a little sub par.

I think if you were able to brew some beneficials you could get
away without using a chiller, but they're not gonna help you with
the DO levels.

I'm really loving it so far, it's super easy. I find myself getting bored
that there isn't more I can do. I'm very optimistic for flowering and
have additional lighting on standby if things get too out of hand for
the two 600s.
