question for bobbong

[stinkyattic]

Wait to transplant them out of the small nursery pots until they have 2-3 sets of adult leaves. By that time, they are probably getting close to rootbound, and you want to time transplants by the condition of the roots.

Bob may have been busy with other sections of the boards, or didn't feel that this was his particular area of expertise- I think for some reason that he knows hydro better? Not sure. Anyway don't worry, that's why we are all here, to pool our collective knowledge!

thanks stinky just wondering those little nursery six packs are those the little things that come with the humidity domes, just hard to judge the size from the pic for me

[stinkyattic]

Well, in this case... 9-pax

[michaelpeg]

thanks stinky, no more questions:thumbsup: except what kind of soil bob used for his cfl grow

[BobBong]

Sorry MP
wasn't ignoring you just had a rough night so i'm kinda hurting today.

ProMix Bx is what i've been using, i'll be trying CocoGro bricks from botanicare next.

[michaelpeg]

thats no prob bob, ok i can get promix bx do you add anything to it or use it as is? thanks thats last Q (for a while) i promise!
thanks alot

[stinkyattic]

I'm not Bob but I use ProMix for plants that I am moving along quickly through my grow, and don't add anything to it. However, I am considering playing with mycorrhizal fungi (MycoStim is the brand I get locally) to improve the conditions in the rhizosphere.

[michaelpeg]

yeah i just read up a tiny bit on the mycorrhizal fungi and it sounds like the plants would love it, how would you go about applying such a thing? i think i actually read somewhere that promix bx has some kind of fungi in there but that could be totally false. by the way at the moment i cant afford a digital pH tester until income tax so could you tell me the pH of the promix bx im sure you got the fancy tools lol

[stinkyattic]

The promix comes from the factory pH stabilized already. You still need to check that your water isn't going to be a problem. CRAP where is that thing I posted on the shit.

Here!

Sez my main chica FoxySox: heh heh heh

I've been using ProMix BX lately and the trick to avoiding pH problems is this:

Promix is stabilized at the packaging plant by addition of lime, a pH buffer (CaCO3). The pH of peat, the major component, is naturally around 5ish. The lime keeps the pH up above 6 UNTIL IT IS USED UP. This occurs because when you add water, you are allowing a chemical reaction (neutralization of the acids in the peat by the lime) to take place. Over time, the amount of lime left will drop, and this neutralization stops taking place.

Your job as the soilless ProMix grower is to keep ahead of the pH!

Typically you will start to see problems after about 8 weeks of the plant being in the same pot. This is because the lime is used up and the peat is breaking down into a sludgy peaty acidic swampy mess. pH will plummet.

So how do you avoid this? Simple!

Pot up into a pot that is JUST big enough for your plants. Time your grow so you are potting up into the next size pot, with fresh ProMix, every 5-6 weeks so that new root growth is ALWAYS going into nice fresh soil.

Staying on schedule, you should rarely if ever have to flush to keep your mix at the desireable soilless range which is about 0.4 pH points below the range for soil.

Good luck.

The fungi comes as a powder and you just mix a little into the soil and it grows and spreads around on its own.

excellent so the key is to keep potting up and pH will be A okay gotcha thanks again and i will be sure to buy some of this miraculous fungi and my 20 manitoba poison seeds are due to arrive today or mon or tues if i get a successful grow out of this it will be strictly due to the information provided by you and bob if you guys lived around here you would get half of my yield.
