Indoor ALL ABOARD, the Atrain 420 EXPRESS!!!

Glad to find your thread, attrain, everything is looking great and seems everybody has been helping you out, see that you're using pro mix with added vermicompost,. You should search thru Google as that's how I found it to be easiest , Google ,muddy pro mix autoflower, and click bottom link where it says more results from autoflower.net. Should bring up a ton of results, where muddy who is a amazing grower on this forums. Has written stickies such as the life of a autoflower. Read thru the threads, he explains what the ph needed for that soil is. And what to add to it. I.e aluminum sulfate I believe he recommends to keep the ph stable. Other than that everything is looking great, start the girls at 50 percent power for the first week and increase. As you don't want all of that light shining on them in the beginning
He also has a great soil recipe using pro mix, with added things such as blood meal, bone meal, earthworm casings

Not sure on the Aluminium Sulphate...looking for more info... @Waira is trying to get some info off Muddy re AlS... apparently not good for MJ per Muddy's opinion... ?? as I say waiting to hear. It is certainly water soluble and INSTANTLY reduces PH BUT it does creep back up over time and has a toxicity effect on some plants. I have a batch of compost which is quite high. It's been sitting on some weed mat for a few months. On the edges of the pile where earthworms have infiltrated, comes in about 7.5, about 9-10 in other areas of the pile. I can either treat it with AlS, or load it into the ground with worms & activated tea's and let nature stabilize the PH over the next four months. I am leaning towards the latter, if it's still high a couple of weeks before planting out, I'll use the AlS as an absolute last resort.

Yeah I went with the dolomite lime from ESPOMA at 1 tbs/gal.... couldn't find enough on the sulfate to feel comfortable and after chatting with trap he uses the same lime on his so I feel better after talking with someone with hands on experience with the medium and admendments

I know, I searched the web hard for AlS info , could not even get a definative answer as to whether or not it was considered an organic or not, albeit Aluminium is 11% of the earths crust, but there was a bit about toxicity and use for blue colouring in flowers. Now my first go at auto's was not real good but I can't put that down directly to AlS, I had very bad weather among other issues. It certainly does instantly reduce PH though.

I use the same lime as well atrian. Its been doing my plants good.

Guys I told y'all exactly what to search on Google -_- yes, lime is great on soils. But promix is soilless. It also includes lime in It, and if I remember correctly both type of limes, the problem isn't keeping it at 7.0 what lime does, but as muddy has found thru his grows more in the lower 6.0s that's why he adds a certain amount like I said, y'all can search it and read thru his stuff. And read what he also comments on stuff. Which is why I suggested searching thru Google. Again like I had stated this is just info I have read from muddy, and since his grows and his info, such as the stickies like, the life of a autoflower, and such are so well received. Then I thought I would share this bit of info I read from him, regarding pro mix. But I guess everybody is a pro mix guru

 

[Vas Deferens]

Um, Dolomite raises PH I thought ?

 

[MisterHarpy]

Exactly

 

[A-Train]

It does... from the other sites and folks I have talked to that have actually used this mix in there own setups..... added the dolomite and it does raise the ph and they said it was added bc after the first month of watering the small amount of stuff added to the soiless mix (pro mix) is gone and they experienced low ph problems not low like 6.2 (Ideal for soiless) like low 5s.

Well give it a shot and mange as best as possible if it works out that's great if not now we all will have greater knowledge on the subject.... and if I do remember correctly folks said time release miracle grow soil will not grow cannabis effectively(not just luck, the knowledge and skill of the growers here made that happen).... I think anything will grow cannabis with all of the knowledge together on this site that can make it happen I'm sure.

Deder, he's in ProMix BX not straight ProMix...the BX has peat IIRC.

 

[MisterHarpy]

Sorry I'm not to knowledgeable with acronyms, what is iirc? I know pro mix is peat based which is why it's soilless, as peat isn't soil.
