Thanks bro
Defo give the DWC a go, its easy as all hell
tbh id grow all mine in DWC's if I had the space
Really the size of the res doesn't matter at all, depends on how often you want to be checking in and adjusting, Larger res means the nutrient solution will be a lot more stable in ph fluctuations and strength, smaller reservoirs will fluctuate a lot more, plants will only take the elements they need from the solution or may only drink the water so may start seeing deficiencies if they are not replaced as needed whereas a larger res will have a lot more on hand when its needed, if the plant is only drinking water and leaving nutrients then if you keep topping it up with more nutes its going to get hot real quick and burn the shit out of your plants
I run 8L reservoirs in veg and 20L in flower, veg I hardly ever need to do a thing, sometimes in that same solution for up to a month just adjusting PH, its only when I start seeing deficiencies or res gets a bit murky I change it lol. 20L flower res gets changed out once a week but only gets topped up with water during the week maybe once or twice, only time I check PH is when I mix up the res and it stays within the ph range all week
The amount they drink will depend on how big they are, the size of the res will depend on how much they drink, you basically want it so you don't need to touch it for the week
Not sure if you remember or not but I ran a plastic tub DWC in my pollen tent for the Sour Diesel crosses with 8 plants in the one tub
Everything went very successful for me, I would recommend if running different strains though to try find strains within the same flowering period, you don't want to try working out a feeding schedule for a 8 week and a 16 week in the same container, its impossible
One thing I did learn from that is 8 plants is way too much if you want any kind of decent yield, you will need to space them out as much as possible to allow as much airflow through the lower canopies
One thing I will recommend to anyone running a DWC is to run a root zone conditioner, they will help keep the res clean and free from algae, diseases and bacteria and will also stop the ph from fluctuating so much in addition to boosting the root zone, there are a few out there and are pretty cheap, I use Rock Supercharge right now which seems to work great, I was using Dutch Master Zone but they don't stock it at my hydro shop anymore lol. Another big thing in DWC is making sure you have enough air pumping through the roots, if running multiple plants id recommend having multiple air stones, at least one under each plant
