Thanks! You gotta stay on top of them. Daily res checks has saved me 2-3 times this grow.Still looking pretty good despite the mishap mate.
Sounds like it was vapor locked. Id suggest way more fertigations, they love it in rockwool; right up to continuous feed during lights on.Opened the tent for daily check ups and droopy leaves right in the face. Not sure how many feeds she missed but the valve was stuck. Pump was turning on but nothing coming out of the 1/4" tube. Opened the drain valve on the 3/4" tubing and pump was working. I closed and reopened the feed valve and there's feed coming out the 1/4" tubes again. I'll have to look into those valves. Can't have that happen again.

I've never considered continuous feed but quickly realized you basically can't overwater rockwool. I run 24hrs on with these autos. Do you think feeding and lights 24/7 would be too much for the plants?Sounds like it was vapor locked.

Right now my mothers are in 4x4x4 cubes and get 3 min on/30 min off on low ppm feed, to keep them somewhat manageable.
The 4x8 flowering tent is 15 minutes on/15 min off during lights on. This is my first grow using other than constant feed during lights on; feeders are off when dark.
Rockwool works so good bc fresh air is being pulled into it as the water runs down through it (similar to NFT), more h2o draining through = more fresh o2 and nutes being pulled in = faster growth and bigger buds. This is the decades old secret that I use to grow so fast and so big. Back in the day it was closely guarded. Other growers that were using the same system, were using spaghetti lines that had a tendency to clog. I was the 1st one in my orbit back then to go to straight 1/4", open tubes. It worked a charm and others soon followed.
I came to this site to pass this system on and nobody's interested. It's cool seeing you growing very similarly...![]()
Nope, not too much; they love it. Feed pump on whenever lights are on; it just keeps the roots awash in freshly oxygenated, full strength, nutrient solution; without drowning them. With the pods I ran, there were 11 slabs with three plants per 4x6x36" rw slab, under 4k watts, hps; when they got guzzling good, a plant would start wilting within an hour or 2 of it's feeder stopping up; this is why I went to the straight 1/4" feeders.I've never considered continuous feed but quickly realized you basically can't overwater rockwool.

It's ashame there aren't more rockwool growers. I haven't grown all the different ways yet but rockwool seems hard to beat for plant development.
The guy/thread I learned this from runs the same 5 feeds every 24hrs and says some plants will drink 5+ gallons a day. Drying out if they miss 1 or 2 feeds. My question now is how much and fast will plants like these drink if I go continuous? My res totes are 14gal and 17gal so I could only get 10gal of nutes in them.a plant would start wilting within an hour or 2 of it's feeder stopping up; this is why I went to the straight 1/4" feeders.
They will drink as much as they want is all I can say. He wasn't lying about some drinking 5+ gal per day. The last big mamma I flowered out, was a 4" cube on a 9.5x8x4" uni-slab on a 27 gallon tote (with a hole in the lid that a solid 5 gallon bucket size root ball fit through). You can grow some monsters on the uni-slabs if you give the roots room to run, either into the res, or onto the ebb and flow table.The guy/thread I learned this from runs the same 5 feeds every 24hrs and says some plants will drink 5+ gallons a day.

The thread is from 2023 so hes not as active but he pops in once in a while. He also does big full grow type updates so less frequent. Seems to me he monitors the thread and replies when hes actually needed. Ive posted some important questions at important times and gotten quick replies. Hes been so amazing about helping everyone over the years that most of the info is already there. I dont mind sharing the link here for everyone. I want to see everyone killing it.Hey, the guy/thread you learned from: are you able to chat with him and ask questions etc? If so, that's awesome; he really seems to know his shite and is obviously a good teacher. You were lucky to find him. If possible, drop me a link in a dm; I'd like to read his thread...
Nice. Thank you for this. I do have air stones and my res is slightly angled towards pump and tray return so it mixes close to pump.I forgot to add in the vapor lock reply, that rather than dead ending it, I loop my 1/2" main line back into my reservoir as a return line, with a valve just prior to where it re-enters. This valve can then be opened or closed to help 'trim' the pressure on the pump and system; with the added benefits of helping to keep the res circulating and oxygenated. (moving surface water imparts more dissolved O2 than air stones)
I mix 5gal at a time and only fully change res when switching from veg to bloom. Since Im only mixing 5gals Im topping with new nutes every week keeping things fresh. I check my res ec and ph daily and make adjustments based off that.Always been curious about recirculating systems. I know the runoff ph should be close to the input ph as long as the volume of feed and total fertigations are plenty. In my head I think the plants drink what they want after each feeding and you basically flush out what's leftover back into the rez each fertigation. That doesn't throw the fertilizer mix out of balance eventually? EC doesn't rise in the rez eventually from the concentrated salts being flushed back in? How often do you guys empty and reset your rez with all fresh feed, or are you guys just constantly topping it off with fresh mix the whole grow? Seems similar to dwc, but I can't wrap my head around that either
This part is correct it is technically a guessing game as to what nutes have been used. The small batches keeps things fresh for me.In my head I think the plants drink what they want after each feeding and you basically flush out what's leftover back into the rez each fertigation.
I was checking in and had the thought to add a general rule of thumb for VPD. Why is it that I cant edit posts after 30 minutes? Not a fan of that feature.And what I do with my lights.
I push as much DLI as the plant will take but 40-47 is my range. Mainly relying on the plant to tell me it's too much then back the lights off a percent or two.
VPD targets
seedling .6-.7
veg .9-1.1
flower 1.2-1.4
Nice! What a noticeable difference! The roots won't dry out and air prune now; they'll follow the drain water back into the res.Noticeable growth in roughly 24hrs of continuous fertigation.
Yesterday before switching the pump.

After canopy maintenance and tucking the main branches.

You are probably aware of apical dominance. You can see how the main branches around the perimeter have their tops horizontal under the net or wire. Thats the secret sauce. Its what makes this method work. It forces the smallest growth to turn into main tops. All that growth that gets lollipoped with normal scrog gets turned into colas.Nice!
