Built an expandable custom 1-4 Dutch Bucket system utilizing 5 Gal storage bins located at Lowes, a 10 gal storage bin from Walmart for the res, ecopump 396, 6" riser, 2 riser adapters with 1/4" drip outlets, 1/2" ball valve, 1/2" threaded pvc elbow, various lengths for 1/2" pvc, 1/4" drip line, 4 pvc elbows, 2 - 3/4" grommets, perlite (use chunkiest possible), hydroton on the bottom of the buckets to keep the perlite from draining down into the reservoir. I made a hose out of 1/2 vinyl tubing to attach to the ball valve to empty reservoir for changes/maint. I purchased everything from local hardware stores, nothing from the hydro store except the hydroton.
I am using Masterblend Professional dry hydroponic tomato and Vegetable formula, along with dry Calcium Nitrate, and dry Magnesium Sulfate. My listed measurements are actually grams per gallon. Trying the most economical way to grow hydroponically and for 6 gal res fill up and changes, it only cost $0.17 per reservoir change or $0.0283 per gallon. I do use RO water and I will be doing bi weekly hydroponic tea additions to the reservoir. I am not running any type of chilling equipment, I have faith in my hydrotea.
For lighting I purchased 2 x QB288 with the heatsinks straight from HLG and purchased a meanwell 320H-1750A driver capable to power a 3rd panel if I need more light for flower. For Veg I am running at 60w per panel and will bump to 110w per panel for flower. These things are seriously bright.
Day 5 moved the girls into their new home.
Day 6 added hydro tea to res
Day 7 I am a moron, in the midst of setting up, I forgot to rinse my perlite. I opened my res today and sediment everywhere and it wasnt the nutrients. It was also coating the bottom of the buckets. So I cleaned out the buckets, dumped and cleaned the res and refilled it back up. The ball valve worked like a champ to pump out the res into a 5 gal bucket. Instead of pure RO, I went with 50/50 tap and RO to make my base water 150 ppm. Upon further research, I was creating a calcium and magnesium deficiency and I do not want to have to add supplements or additional Epsom salts to keep this as KISS as possible for a hydro grow.
This is my first dutch bucket run and my reservoir pH is rising quite a bit daily. I pH down to 5.8 to 6.0 and within 24hrs it's back up to 6.6 6.7. Rinse and repeat. Is this normal or is something out of whack. I know pH will drift a little in a hydro system but this much?
@Ga4rd2en0er Thats a hard name to write , What is the ppm doing ? is it rising or falling or remaining the same ?
usually it will rise like that if the plant has taken up a heap of water thus changing the ph of the now more concentrated solution
@Grey_Wolf the ec drops slightly per day and seems to be drinking about a gallon of water per day right now. Been topping off with nutes to keep it in the 1.7 to 1.8 range.
@Grey_Wolf, last res change and it was clean as a whistle. I do 4 gal ro, 6 tbsp molasses, 2 heaping scoops of great white, and 3 to 4 handfuls of EWC in a sock and brew for 48 hours. I then add to my reservoirs at a ratio of 20 to 1. Aside from my indoor dutch bucket, I use it in my outdoor kratky tomatoes peppers herbs and lettuces and all have brilliant roots even with 80ยฐ res.
@Grey_Wolf, that's what I was thinking just the sharp rise in pH alarmed me. I inoculate bi Weekly with a tea I brew with EWC, great white powder, RO water and fed backstrap molasses.
@CRiSPrGrow I ran out of hydroguard and have been supplementing my res with hydro tea every 2 weeks to build up benies since I am not running any type of chilling for my res, So for me H2O2 would be a no go. Tea has kept roots of plants outside in kratky setups bright white and happy with res temps in the high 70f to low 80f. I'm probably being a little over critical as this is my first true hydroponic run.
@CRiSPrGrow, thanks Nova, I inoculate with great white myco powder and earthworm castings fed with backstrap molasses. I can see being myself being over critical, it's one of the reasons I smoke ๐. Thanks again growmie!
@Ga4rd2en0er, yes to everything you said let me just add it might be a good thing to add bennies to the tea just to assure it's got that chelation power, but yeah most of it is probably being strict on yourself growmie ๐ ๐
You look to be of to a nice start with our Auto Original Amnesia ๐
Happy and healthy just what we want to see at this stage of growth mate ๐ค
Good luck with the grow ahead my friend ๐
I'll be along for the ride and watching with interest ๐
All the best โ๏ธ
Mark..
@Wicked_Stix, unfortunately I tried that and the buckets are far to wide mouthed compared to the 5 gal bucket. I'm setting up an outdoor Dutch bucket with reg 5 gal buckets and will definitely be using the strainers.
I love how you've named both plant's my friend, very cool ๐ค
Lloyds time is nearly up with Harry coming down a week later ๐
Both plants look absolutely stunning mate ๐ค
Well played ๐
All the best โ๏ธ
Mark..
Things look to be going into overdrive mode now ๐ค
Big fat buds dripping in trichomes, what's not to love ๐
Looking good in here ๐
All the best โ๏ธ
Mark..
They are looking great!! There is definitely something is your feed that is messing your ph up. The maxigro and maxibloom are the most stable nutrients I have found. My ph will hold stable for 2 weeks without adjustments.
Ph goes up because sheโs drinking all the nutes our the water.
Try running beneficials instead of H2O2 Hydroguard is good example.
Best is to brew a liquid tea using compost molasses and strains of bacteria and fungi. You will have the pinnacle of health and flavour smell will be increased
Rather than nuking your way to root rot then bud rot, try the natural approach XD
Read your comments after I posted this... lmao
@Ga4rd2en0er, unless youโre adding beneficial to every feed youโve got chance of brown slime especially in res temps over 18c.
Wipe the side of your res with paper towel. If a load of brown slime on the side/bottom of res.
I would go ahead and do a H2o2 bath in your res, get some new air stones and see if that makes a difference.
As your in flower you can use phosphoric acid instead of nitric acid which is more common.
1 more thing this might help
If you dump the water in cold then put nutrients in, the PH will change as the water warms up...
Good luck, let me know how you get onโ๏ธ
@PharmaZ, I've used straight ro, I've used straight tap, I've used 50/50 mix. I mix all my nutes for a while in a 5 gal bucket to ensure no precipitation of the suspended nutes and have a small pump circulating the water within the res along with 2 large airstones powered by a 10 w pump. First thing I do when I open the tent daily is check ph then adjust and work on plants (lst, defoil, etc) and check ph again when done. Not sure if maybe the tnb down is crap, first time using it as I ran out of trusty old GH ph down. I think after this run I'm going to build a platform to put my tent on and use a larger res outside the tent. My res is only 7 gal due to holes in the latching handles on the tote. Thanks for the input and keep the ideas coming!
So many massive colas on this beauty. Nice work. 15 weeks is an old auto on here, but I think many people harvest too early. Yours surely shows the Benifits of patience. Congrats. Keep doing what your doing and best of luck with the rest the grow.
@Denzul, they definitely tried my patience this run. But with the bad pH down I was using, they had a rough first couple weeks of flower so I think it elongated the flowering window. Fingers crossed this weekend and the last one will be done.
Hell friggin ya buddy. What a harvest! Holy crap! DOTM contender for sure. Congratulations man. This is serious quality and a serious yeild. Unbelievable ๐ฎ.
Great work, well deserved. Happy smoke my friend!๐๐โบ๏ธ
Holy crap this is nice. Look at that frosting! You're in for one hell of a treat and you've done these genetics proud. Very happy to see you nearing the finish line. I'm genuinely excited for you, it just all looks so good.๐
Cheers and continued success my friend. Bring her home!โ๐
