yep

depends on the mother plant. A healthy, vigorous mum may deliver 8-10 thick stems (>5.5mm, often 10mm dia).

I have space for 10 mums, but some of them are not used for cuttings- they are young replacements which are being vegged up in anticipation of taking cuts from them in the next few weeks. There's usually 8 plants that I am actively using for my 30 cuttings every 2 weeks.

Hey Al i hope all is well in ur neck of the world lol, i was hoping you might have a look at my diary quickly and let me know what you think... im still having temp probs with the cooltube but ive managed to get it down to a constant 26celcius and im waiting on an 8 inch fan arriving tomorrow, but like an idiot i didnt transfer the plants into solid pots straight away, so the roots have grown through the bottom of the net pots and onto the flood table, meaning they are under the light.....

Im gonna transfer them tomorrow into solid pots which will sort it out but is it gonna do any lasting damage to the plants??? Also will the 10 days of 28celcius cause me big problems later???

As always Al you give the best advice which is hy i come to you, without bein an arselicker.....

AL B ROCKS

Sorry i aint got the chair but im gonna find a new one for ya.......thanks again bro

"Also, the cooltube should push air through the cooltube instead of pulling it. It is more efficient for the fan to draw in denser cool air than shift warmed air. A pusher arrangement allows the fan's motor to be cooled by the airflow instead of being heated by the waste heat from the lights, which could conceivably shorten its lifespan."

Thank you - this is very useful. I have mine hooked up backwards.

Better. Hope the 200mm blower brings the temps down. Make sure that the path for intake air is not restrictive.

Wrats. If there's not a lot of escaped roots (10mm or less outside the pots), you can trim them off, pull the plant out of the netpot and drop them into std pots- but if there's significant development of the roots outside of the pots, don't try trimming the roots off. You will give the plant a case of transplant shock, slowing it way down. Just get through this grow and use the solid wall pots next time.

The plants may show some mainstem elongation later on, but hopefully you will get the temps down to 24-26C for the remainder of the grow, which should prevent your buds from bolting or becoming 'runny,' where long strands of bud material are formed instead of tight, dense nugs.

Easy fix, just turn it around.

I think (could be wrong) but its also at a slightly higher pressure but offers more air mols to absorb heat. (but then compressing air heats it up too. Probably a wash/splitting hairs)

Hey Al, I was hoping you could stop by my thread and see my grow. I have just noticed a deficiency that I am unfamilar with. I belive I saw a photo you posted of the same sort of problem, but I cannot find it.

It would sure be appreciated.

Cheers!

Yes, true, there's more air molecules per litre in cooler air, which would indeed be able to pick up more joules of heat per litre of air.

However, an axial blower will not compress air enough to change its temp significantly. Boyle's law will tell you just how much the air temp of compressed air will rise, but since axials are designed to move large volumes without developing much pressure downline, any air temp increase measured from the output of an axial blower is more likely to be caused by heat from the fan motor.

You're shooting the pH too low at 5.3.



Needs to be 5.8. At 5.3, you are locking out N, P & Mg.

Keep in mind that deficiencies caused by an actual absence of certain elemental nutes are extremely rare when using a commercially made hydroponic nutrient. It's much more likely that a pH error is locking out certain nutes.

Now is that to say that an axial fan with a down stream restriction will stall the blades of lift before compressing the air to any degree of temp significance? (sorry, tend to think inside the box next door at times.)

But I do like the push vs pull. (as a side note: The original PC power supply's fan was an exhaust by mistake. It worked, so it stuck as de facto standard. Same holds true for the twist in the floppy drive data cables A-B. Am I dating myself here? )

On another note, I have an sealed air cooled hood almost ready to go in. Is a cooltube that much better then a hood? Its a narrow .2m D x 1.75m W x 2.5m H grow room/closet. But only plan on 6 smaller plants under it (400W) in a 2x3 config, currently under 2 150W (I like the spread of the pair)

(also in soil, so need a little more floor real estate, but in general.)

Also planing on one of these for the hood:

Soler & Palau Commercial Centrifugal, Axial, Propeller, Exhaust and Supply Fans - Soler and Palau - HVACQuick.com

The TD-150. They are claimed to be a hybrid of axial/blower. Seems a good contender. The Pano's are just too expensive for a house I don't plan on dieing in. See any downside to them? (the S&P's)

Thanks for your advice Al, im gonna get some solid pots tomorrow and see if i can still transpant them, however if i have to cut any roots ill just let them be, but any advice on what i should do with the roots, ie, cover them up somehow??

Also i dunno if you looked at my journal but the flimsy cololtube reflector jumped off the other day, and broke a fan leaf at the stem, however its still half attached, should i cut it off, also the first set leaves that grew havent grown for 10 days and are a lime green and look wilted, in my opinion dead, should i cut them off?? As a noobie im a bit anxious about cutting my babies, but i trust your advice so if you could lend an opinion would be much appreciated....

Just 1 last thing, in fact 2.....when you clean your res what do you use? Can i use a household cleaner as long as its rinsed properly, or will this be detrimental to my plants if some stays in the res???

And i saw a link a while ago for H202 in the uk as its hard to get, ive searched through loads of pages looking for it and i ust cant find it, if you have the link could you post it....

Thanks again Al, i like many others would be very worried without some of your input, and if i could make any sort of donation for your advice i would, not that you need it from the sounds of it you got things tickin over very nicely, and hopefully 1 day ill have the same success you have....keep up the good work bro
