i want 1400ppm for immediately starteing flower from clone? and 5.8 ph right
yep.
ive also got the thermometer your talking about i just have to finish making the patch in wall for my ventilation into another room dont like venting out of the house
Smart move. However, if you have the possibility to dump exhaust into an attic, that's a better solution. Not always possible, I know.
im not vegging at all just cloner to flower like your set up in harvest every 2 weeks except not perpetual harvest
When I use the term 'perpetual harvest,' it's a relative term. It's a comparison to old style ops where the entire flowering area is filled with its max capacity of clones at one time and that roomful gets harvested all at once in 8 weeks when mature.
The 'perpetual harvest' concept means you are only feeding in a portion of the room's capacity at one time, waiting for some period, much shorter than the 8 weeks between harvests in the other style, then feeding in more plants, thusly spacing out the harvests.
In the system I designed, I decided (quite arbitrarily) that every 2 weeks was the desired harvesting interval. Since flowering runs for 8 weeks, it was convenient that I would have 4 flood trays, each suiting a 2-week span of flowering. Plants would be moved from tray to tray through the system in an assembly-line fashion. Clones would be fed in every 2 weeks until the line was loaded. An equal number of matured plants come out of the other end of the pipeline in 8 weeks' time.
So, 'perpetual' is a bit of a misnomer. You can't walk into my op on any given day and find a plant ready to harvest. Plants go in to flowering in waves every 2 weeks and so come out in waves on the same schedule. When I use the term 'perpetual harvest' I may more accurately mean 'regular harvest,' and in the case of my system, every 2 weeks.
so one last question for now when i move forom cloner to flower room should i be giving them a mix of grow and bloom nutes or just bloom and calmag(i put calmag either way)
Clones don't generally need any nutes until they go into the flowering room, when they can start right away on 1400ppm flowering nutes.
An exception might be if you must hold the clones in the clonebox for longer than 14 days. I have that very problem at the moment. I had some trouble at the beginning of winter getting clones to strike. Clonebox got too cold, fixed it, but not before I had about a 6 week gap in getting good batches of clones striking every 2 weeks. This meant that the plants in flower got to stay in the room a bit longer. However, if a plant is left to flower too long, problems like hermaphrodism may pop up, requiring that those plants be harvested ASAP. I left tray 4 to flower for nearly 12 weeks, tray 3 for 10 and tray 2 for 8. Then I had a lot of empty tray space to refill with cloneage. That sort of event fully stuffs up the rhythm of the op. Now there's another logjam of plants not mature enough to harvest, so clones have to spend a long time waiting in the clonebox.
Clones don't generally need any nutes before they go into the flowering area, when they are started straight away on flowering nutes at 1400ppm. They're living off nutes stored in the leaves when the clones were still attached to the mother plants. After about 14 days in the clonebox, they start to look a bit N deficient. Since they have good roots, I've given this mob a weak veg nute soln (400ppm) to keep them from getting too starved until they can go to flower. I expect some more veg growth out of these plants in wk1-4 of flowering. We'll see how we go.
sorry, on page 30 you were discussing how expensive centrif fans were and the last post on that page someone posted a link to centrif fans, over here(in the sunny UK) they're cheap as chips!
heh, I see what happened. You replied using the input box which appears at the bottom of each page. Unfortunately, your post appears at the end of the thread, not in the page you were replying on. 5 pages later, we've forgotten everything already.
I have accts at a couple of wholesale hydroponics supply houses in Aus. Axial fans, even at whoesale, are still much, MUCH cheaper than any centrif. A good 150mm axial can be had for about $50 while you could not touch a 150mm centrif for under $200. Centrifs are more expensive because they must be made to much closer tolerances thatn axials. The impeller vanes must run close to the blower's housing for them to develop any pressure, which is what they do best. They must be balanced and the impellers have to run true. Axials can wobble and rattle and still work just fine. Centrifs won't.
