just got rid of led light bc it was weak, another member here suggested i go with CMH lights and thats what im going to do, 2x 315 cmh's and i heard there are remote pieces i can get for the CMH to keep heat out, im not sure what im really talking about but swear i saw something on that.Hello. It looks like a nice set up you are planning.
35 sq ft is a big area to light. You will want 40-60 true watts per square foot. Some 260w LEDs advertise as 1000w replacements. What kind of light do you have exactly?
I would suggest reading into VPD, knowing your ranges can let you compensate for temp by adjusting humidity.
Minor things that stand out, putting those rooted cubes into expanded clay-filled net pots might be better than 4-inch Rockwool cubes. Keeping those at the right wetness is a pain while waiting for roots. Ymmv
If you are cutting holes then don't skip on quality hole cutting drills. A roll of plumbers tape is helpful there. Leaks suck.
Reservoirs outside are great if able to plumb it. Might want a bit bigger size in case you want to be able to leave it for a bit.
All my advice is from a noob perspective. So take whatever is useful.
Good luck!

What is VPD?
okay ihavent gotten all this yet but was planning on it this week, so ill get clay instead, is there certain types that are more quality?
the rooted clones are coming in 1.5 inch starter cube if this makes a difference but they are fairly good sized clones.
My unc is an engineer and built his own legit ass system and hes coming out to help so going to let him do all the holes and plumbing lol, hes a little more detailed than me. but thanks for the tape idea.
i think i can i place the res right outside the room, but your saying get a bigger res to change the water less?
May I suggest hydroton instead of 4" Rockwool cubes... I have a feeling they will end up a soggy mess for you.
Also suggest slip bulkhead fittings for buckets and PVC not ABS for plumbing.
I find the 4x2" airstones work well. 1 per site and can do 1 in the res. They require about 10 lpm so about a 1000gph air pump would be needed.
What kind of environment will the system be in? Water temp may need to be looked at
i dont think my water is good so i was hoping maybe 50/50 with filtered water from those water dispensers, I really dont wanna have to get or build a chiller unless a killer deal.Chiller and RO unit unless you have golden water
Keep the res outside the room and you may get away without a chiller. If it's in the basement right on the concrete. I know ppl say don't do it but IMO a $50 aquarium heater is a shitload cheaper than a chillerjust got rid of led light bc it was weak, another member here suggested i go with CMH lights and thats what im going to do, 2x 315 cmh's and i heard there are remote pieces i can get for the CMH to keep heat out, im not sure what im really talking about but swear i saw something on that.

Use bubble wrap insulation for buckets.. much better than mylar. Can find it at most hardware stores.i am completely opened to anything haha! but what's the diff between hydroton and clay?
Noted, how do i figure out sizes for piping and air hoses?
What do you mean environment? like what state am i in or where is the system growing specifically? Socal, walk-in closet ( one door/no window / no ventilation )
4x2, are those rectangles or discs? I was under the impression that disc air stones are better than the other shapes.
For water temp, i was hoping with remote res and remote CMH light equipment ( if possible saw something about this on some forum ) outside and adding a small ac unit would keep my temps under control, I am also wrapping the buckets and any water with mylar.
The ground is cheap vinyl on concrete with thin floor padding its usually cold.Keep the res outside the room and you may get away without a chiller. If it's in the basement right on the concrete. I know ppl say don't do it but IMO a $50 aquarium heater is a shitload cheaper than a chiller

okay ill use bub wrap on the plants and water but my walls im using mylar.Use bubble wrap insulation for buckets.. much better than mylar. Can find it at most hardware stores.

You either need ventilation or you will have to add a dehuy, AC, temp and humidity controllers and CO2 supplementation. Ventilation is much cheaper.
okay, i was looking at those spider farms but aquaman suggested CMH lights at the end of the day they might come out to the same price or close to it. i have another thread on lights i was looking at, see here mate: https://www.thcfarmer.com/threads/need-help-lighting-5x7-room-with-6-plant-rdwc.113691/#post-2431552The most important thing is light.
A remove CMH involves putting the ballast (metal ppwer box thing) outside room. But those bulbs are still very hot and would need its owm dedicated enclosed hood with 4 inch vent hose on either side cooling it.
I would heavily suggest you go with Quantum boards for this situation.
You need efficiency to reduce heat. And the newer QB leds are the sweet spot right now. Use the 40-60 watt per sq foot as a guide to know how many you need. Can be multiple seperate lights, that is better for spreading out light distribution. Look at a Spider Farmer 2000 on amazon to get an idea, then there are lot of diy options or chinese stores to get same thing cheaper.
The light situation is definitely the most important to sort out and the second and related would be the ventilation. The good thing is you can start with just the under door thing you suggested because the clone won't need full power light at first and you can add more ventilation options or go with cutting a hole in the door if you need to later on after you do some testing.
I think hydroton is just a name brand or way to describe the generic term which is expanded clay pellets.
I've never heard of there being any sort of quality difference between different sources if it looks like hydroton clay then it's good.
Aquaman really knows his stuff so I would certainly take his advice
Hope my noob perspective is helpful
okay wow i thought colder water was better, is there a guide on water temps for RDWC throughout the cycle?Heater is there because cold water is deadly and the floor on a chilly day it might cool it too much. Hot water is only a problem for microbial and a lack of oxygen which can be made up for with more oxygenation to a point and cleaning out your Reservoir occasionally.
I could be way off on that one though
thanks for the insight, i knew i needed at least two 315's. How do you cool them then or you dont you just cool the rest of the room? Its almost loolking going cmh will be more or the same as LEDs with all the necessary equip but i may be wrongI wouldnt go the aircooled route with CMH. The hoods specifically for that that are indirect airflow will usually run you more with a fan then a small A/C unit. You shouldn't directly aircool them or they end up shortening bulb life and using more power. The ramp the wattage trying to keep the bulb in an operating temp range. This is true for DE systems and from what I understand the same for CMH. You would also need 2 of them for that area. 315's = 3x3 max really.
I don't know what that ends up being price wise for you and can't comment on boards, since i've never run them, but 315's and 630's are the truth.
how many liters or lbs of clay pebbles i need for 6X 6" net pots? curious can they be reused?May I suggest hydroton instead of 4" rockwool cubes... I have a feeling they will end up a soggy mess for you.
