BooMer's 5000w Medical Hydro Cannabis Laboratory w/ C02 Generator & ScrOG

As far as Ive been reading only about 1 percent of the oxygen your roots uptake is from the water and the rest is from the air. So having lower dissolved oxygen isnt posing a prob cause there is still plenty of oxygen in the water to give the plants this small 1 percent. Dont quote me on this info Im no botonist. This is info gathered on the web. I think if your running sealed containers with bubbles[aero, bubbleponics, dwc] the oxygen in the water is more important, but for basic hydro systems Im not sure how necessary all the oxygen really is. The roots intake their oxygen at night from the air in the medium mostly. Im not saying Id remove my air pump, but Im thinking the higher temps will be ok. Anyway Im gonna try it out with higher temps in my current grow and we'll see how it works out. Ill set my heater at 70F and Im sure after that and my room being 85F it will quickly rise to room temp. If nothing else we will have a good experiment to learn from.

from my research and other large grows ive seen, a chiller is the way to go (where have I heard that before) <rolls eyes> supposedly roots uptake better at lower temps and lower temps scare off pest fungus mold etc. (you are partly right. The main reason for lower res temps is to increase the dissolved O2 for your roots. The main reason you have all those bubblers is to raise the O2 levels. If the water is warmer you loose all that O2 and root preformance) mite not be completely correct about that part but another part is the last two weeks of flower if u have a rez is to lower ur temps to like 50 and trip out the plants colors. mainly turn purps purple.

anyways a 1hp chiller is around $1300 and a pretty penny so depends on ur budget i guess. my grow seems to be fine with water temps at 75. so idk for sure yet

Wait until this summer when the outdoor temp is highter. Check into the DYI iceboxes for cooling ligh hood exhaust (https://www.rollitup.org/do-yourself/234834-diy-icebox.html). No need for AC then.

Grow is looking good. pH will be easier to keep stabilized with constant temps. PPM will fluctuate mainly from nute uptake from hungry plants. Buds are starting to fill in. Now the good part begins.[/QUOTE]

ill prob end up buying two chillers after this crop out for my next setup anyways so ill use one of them for this coming summer to cool my rez down.
i researched ice boxes and not into them anymore. just more work to run hosing to the lights and all that. i have a 2ton AC in the room already so that controls my temps

nice setup you have there so hows your power bill with a setup like that

not bad at all actually since my doctor signed off on edision to have my power bill in a lower tier
-thanks raiderfan

I have seen old window ac units turned into chillers, I wouldn't have a clue how to do it myself but i have seen a couple DIY threads on it on other sites so you may want to look into that if you dont want to shell out the 1300$ for a chiller. Just a thought.

DIY is cool but im way too busy for DIY projects right now. id rather reinvest my funds and get new equip at the wholesale warehouse and make sure if it breaks they can replace/fix it

but thats good info for others on a budget

I like your style boomskeet.
I know your not interested an AC probably has a 1/10 HP chiller, nothing like the ones your are looking at.........

WHen you said you had your doctor sign off on edison to lower your power bill or be put in a lower tier? can you explain this a little more for me please sir. THank you

I wish you luck my friend. With your res temps @ around 85 degrees and low or no O2 in your water, your system will be ripe for root rot amonst other things. THe intent in keeping the res temps lower is to prevent the root rot and enhance the capacity of the H2O to carry O2. That is why everyone uses bubblers in their res; to put O2 into the water. To put it simply, if the water temps are high the carring capacity of the water is very low. Low O2 to the roots = not optimal root health. Your plant will grow without nutes too but not very well.

Sorry Boomer didnt mean to thread jack.

If you do get a chiller, look into you res capacities; a 1 hp chiller can reduce the temp for a given res capacity by 10 degrees. A 1/3 hp chiller is good for a 10 degree drop in 150-200 gal res. Also look into cooling diffusers (copper or aluminum coils) which go in the res. Some chillers have an operating range (i.e., 55-65 degrees or 65-75 degrees, etc.) too.

sofa king nice plants.

theres a form on edisons website to fill out and have ur specialist doctor sign off saying u need special power needs at home. he did it and edison approved it so it gives me a .16 allowance per kw/hr

no worries GT. a little insight to o2 in h2o2 is always good info.

ill be doin 1 HP chillers (each for the under current rez)

glad u could swing by brotha things are gettin legit now

WHat size res are you going to use? That is a big ass chiller for anything undet 500 gal. Like I said the 1/3 hp is good up to about 200 gal for a 10 degree drop. Plus if you use cooling diffusers it is even more efficient

the under current dwc system uses 13gallon bucket sites with a similar sized rez connected at the end. using a recirculating system with mass pumps and air. so its 13gallx36 sites and i want to cool my temps down as low as possible in the event id like to change colors in the last two weeks of flower.

i will also have a 200gall rez to mix my nutes in and top off my rez via float valve on the main rez bucket.

just to put things in perspective heres jackmayoffers grow that im workin with chasing that white rabbit...


fyi his system was the first setup using only 8gallon bucket sites. the 13gallon are expected to produce even more.

"Caution; do not try this at home..." lol

I have no words for that!

just breath taking!!!very very nice set up

Better bring your A game to that setup. Very nice.

That setup is SICK! But yes I am also guilty of lurking.

got bored after cleanin up the room decided to mess with the new DSLR and found the daylight white setting along with tungsten and white flouro settings

anyways its nice to get sum quality pix workin for me. figured id share.
so enjoy sum bud porn. kinda like bee sting sized for now but theyll be ready for motorboating soon








tables on wheels makes for nice easy inspections
























heres a challenge for u guys. diagnois these fan leafs. lol

room looks great even with lights off, loving that green light!!

Great find on the other grow thanks for sharing
