ProMix... Is it considered hydroponics or soil gardening?

    And if your promix wont absorb water too well you could always add a few drops of liquid dish soap to act as a wetting agent

    i've used pro mix for a while, and if you stay at 5.8 it's going to be too low, you need to center around 6.3, dropping down to 6.0 occasionally, rising to 6.5 occasionally, but always returning to 6.3

    its hard to find anything but the basic pro-mix here, so i buy it and chunky perlite and mix it myself. i like to put about a 4 inch layer of pure perlite in the bottom of my hempy totes anyway, before i load em with the mix

    I started using Pro mix recently but its hard to get here and expensive. I noticed that Premier peat moss is made by the same company as Pro mix and is cheap and readily available. I get perlite for 10 bucks a 4 cu ft bag so I wanna make my own. The promix bag says about 75 to 85 percent peat and the other is maybe split between perlite and vermiculite. My question is how much lime should I add, and is Dawn dishwasing soap a good wetting agent?

    Not sure how much lime to add, but be careful with soap. Yucca would be a better option.

    Id go coco

    Yucca is a great natural wetting agent

    Dont know about the lime crap but

    I would at least mix it 70 pro 30 perlite :)

    i wouldn't use vermiculite, it retains moisture, and the whole purpose of mixing in anything is to get better drainage.
    70-30 is a good ratio, for either coco or pro-mix.
    here's the thing about lime. it's not that great for plants in pots, it tends to hang out for a while, and interfere with absorption of sulfur.
    you'd be better off a small bag of calcium nitrate, a bottle of cal-mag, or a foliar spray like yield booster. the chelation they use on fertilizer is supposed to keep the sulfur and calcium from reacting and precipitating, but i don't trust it, i've seen dust in the bottom of my fert buckets when mixing them., so i use a foliar now. a good spray every two weeks and no worries

    i've never used a wetting agent. never needed one. peat can develop hydrophobic pockets, IF you allow it. water it regularly, slowly, over the whole surface of the pot, and you won't get dry pockets

    I was gonna put the lime in cuz that's what in Promix for Ph, I have a 25lb bag of calcium nitrate, how much to add? I'm using Jack's Hydro 321, so wouldn't that be enough calnit?

    don't add it to the peat, just water with it, add it about the strength you would add cal mag, just remember it has N in it as well.

    I thought lime was only used to sweeten acidic soils anyway like ph raiser why do you guys use it?

    i use it in my garden outside, to do exactly that, but it's a good source of calcium, especially if you buy dolomite lime, which contains magnesium, as well.

    ok so what ph do you guys that use promix ph your nutrient solution to? I had to take a 3 year break from gardening and ran into a yellowing issue in early to mid bloom.. Dont wanna run into this issue again.. Ive been ph'ing my solution to 6.5 after i tested my solution and found out i had fed at least 8-10 with fucked up ph nutrient solution... ps.... advanced nutrients ph perfect is not ph perfect, takes my nutrient solution down to 4.5... Ive quickly learned not to become to comfortable because when you do, you forget stuff and that can ruin a whole crop. I was to comfortable and totally forgot to test my ph, easy mistake that i completely overlooked
