The mums will be in the same resevoir as a DWC. I need fast growth as I want 100 clones every 5 weeks from the mothers. I'm thinking of keeping 2 mothers in the resevoir to get 50 clones off each

I am trying to reduce the number of reservoirs I have to monitor constantly At the moment I have a flower res, veg res, cloner res, mother plants res. I've noticed if I give my mother a low feed of nuts it's fine it doesn't need over 600 ppm. I'm curious as to whether other people manage to...

Good to know, so how many rotations do you aim for per hour to avoid air stones?

Ah right I get you. Do you use air pumps in yours or do you have enough DO from the flow?

Yes I meant 14500 lph. The system contains around 400-500l of water though so the rotation depends on the total volume. Do you have any example of a multi outlet manifold? I don't understand what you mean. I have a control bucket where the pump dumps water from the return line. I'm hoping...

Got plants in at the moment with an air pump so I'll have to wait 8 weeks or so so I can drain and modify

Yeah those are the ones I mentioned above where people talk about it being possible but don't really give the amount of circulations per hour etc needed to know at what point it becomes possible. I'll upgrade my pump to 145000 lph the biggest I can get and see how to goes from there. Might have...

I guess I'm gonna have to, thought someone might of already attempted this

I can't really implement anything like yours when I have 30 DWC buckets I need aeration all through the day as the roots are directly in the solution. If circulation does the job it would be the easiest solution for me

If it drops into my tank and takes a whole hour to circulate around and come back though that oxygen is going to deminish before it gets to the last pot. So I'm trying to find out how fast I need it to circulate as I don't know how fast my 2 inch bulkheads will allow water to drain to next...

I already have a chiller and water temp kept at 18c water pump is not submerged so heat not an issue. Just trying to establish what flow rate would oxygenate the water enough

I'd need like 30 of those pumps tho for the DWC system I've just setup so I'd rather go with a system that recirculates so fast it stays oxygenated without any air pumps at all. I've seen posts by some people saying they do it and call it high flow RDWC but I can't find any mention of the flow...

I've seen some people mention that circulation alone is enough to aerate the water: I'm just wondering at what point can I get away with no air pumps? If I have a 300l RDWC system and a 4000 lph pump circulating the water that makes the water do a complete rotation 13.3 times an hour or every...

Great cheers I'll get building

What about for the mothers? Do you reckon 17w per square foot would get enough growth on mothers for 50 decent clones in 5 weeks of growth topped several times and kept short?

im building a separate clone / mother room I plan to keep the clones in the room for a few weeks but they will be only 4 inches tall and just topped with 4 tops ready to go into my veg room. Would I be able to get away with 1 cob per sq foot running at 17w each, total 34 cobs On a hlg-600h...

I'll stick to the AC units only then however, In total in the room I have 7200w of cob leds. It's in a confined space due to being a vertical setup. In total including water pumps its more like 8000w then the AC units use 3000w so that's a total of 11000w in the room x 3.8 = 41800 BTU PLUS the...

I'm trying to get my head around something. I can't work out if the evap cooler will actually reduce the temperature in my room in my situation. I have 5000w in a room and I'm getting a 36000 BTU AC to make sure I have enough. It will be a sealed room I'm concerned 36000 will not be enough as...

My seedlings are in a 4 inch netpot in grow stones, those stones are impossible to tell if they are wet or dry. How do people do flood and drain with rock wool cubes only? Rockwool must be always soaked?

ive had many successful grows however I start from seed very rarely. I started new seeds 2 and a half weeks ago and they are barely in second true leaf due to massively overwatering. I have them in a a small rapid rooter and then in a 4 inch net pot filled with grow stones. It's absolutely...
