Thats very chilly for LED. I would expect much better growth rates / yields in the 80's BUT that could cause issues with nutrient temperatures.

Yeah I've considered adding a space heater to the tent, but without a water chiller the water temps are perfect and growth is still beating the hell out of the soil tent I haven't brought myself to that point. The Quantum boards just don't add much heat. Almost makes me want to pick up a used HPS for cheap just to warm up the tent when I go to the bigger set-up.

Those stalks are huge! That little net cup is gonna look like David Banner’s shirt when it’s all said & done!

Its already busting open. Hoping that I don't lose any hydrotons before harvest.

You can improve the canopy coverage...

1. Tight the net scrog
2. LST
3. Topping on younger plants ( right)

I have a second net going in about 4-6" above the current one during flower. I'm not sure I want to top the small plants as I'm flipping tonight. The 4 bigger plants have all been topped multiple times and got a rough supercropping last night. The next build will use pvc piping to build ultra tight scrog nets that will stack Hygro Hybrid style. This run I'm making do with cheap vivosun netting.

nice set up

The plants are in Day 3 of Flower and are happy with the new ratio of nutrients. I'll be taking clones soon.


I finished my design for the new system. It is 6 sites of 27 gallon totes and a 27 gallon Rez using uniseals and 3" PVC piping. I've kept the under current style, but I'll be adding an additional pump to supply top feed waterfalls for additional DO. The set up is similar to my last design, but I've spread out the totes in order to scrog more heavily and give myself space to work with the plants. I have a ball valve between the Rez and two others in the same drain/Rez fill off the recirculating pump as the smaller set-up.
I'll be building 2 layer pvc scrog nets to cover the totes and keeping with the 3500k +660nm quantum boards. The idea is to keep using my small set for a 2 month veg and then moving the plants to the new setup and immediately sending them into flower.

If you guys have any suggestions or pointers, I'd love more advice.

you could replace the 4 "L" s into a single one maybe

The pump might be too close to the tote when your roots grow big. A screen beforehand might help, keep it clean to keep the flow.

Hey Everyone!
The plants begin week 3 of Flower tomorrow and are looking great.

I have been defoliating like crazy for weeks, but they keep packing on the leaves. I'm just starting to see more stretch and the hints of bud formation, as these are all around 10 week flowering strains.
They've been fully on double strength week 6 GH trio mix going in at 2 gallons a day trying to keep my PPM in the 700's. They are drinking and eating like crazy with no signs of deficiencies or nutrient burn and my PH drifts up barely a tenth each week. I'm very happy with the growth although l'm itchy to see more bud formation.

I've had no issues with root clogs and I made a somewhat sloppy, but effective fix for the ripping net pot that will prevent it from falling through.

I'm really happy with how this grow is progressing and can't wait to use these buckets for a nice 8+week veg and then flower monsters in the new setup. This system will easily fill up my 4x8 Tent over the flowering period of my 8x8 tent giving me a nice harvest every 2 and a half months or so. I'm also really interested in running some of my favorite auto strains simulateously at some point.

I also revised my 27 gallon Totes design using everyones' advice and picked up most of the supplies needed for it as well. I removed several of the elbows in the piping and decided to build a little kneeling platform over the piping in my way. I also lengthened the pipe headed to the main circulation pump considerably. Considering how much water the plants are consuming at this size, I've decided to add a large external fill tank with a float valve that will sit above the control rez so it's more hands off.

I'm also considering picking up a few more lights. I built a bunch more of DIY 7 Bulb fixtures using 3000k 14watt household LED bulbs, but I'm thinking I might need a bit more power due to the lower effiency of these over the LM301B boards.


Measuring the planned grow space in CAD calls for 1236watts at 30watts/sqft. Between my 4 QBs at max and my DIY Fixtures I'll be about 1500watts. I kinda feel like it would be better to have more and run the QBs at a lower setting, but I'm not sure I want to commit to more garden expenses yet.
Thanks for following along!
