I've been using ProMix HP for a while with good results. I had to add 2 tbs dolomite lime per gallon, but no perlite.

My local garden shop was out today, so I bought Sunshine Mix #4 instead. I've read good things about it as well.

Questions:

1. Do I need to add any perlite to it?

2. Do I need to add any dolomite lime to it?

Thanks.

from what i understand, its ready to go as is, i have a bag of it, not used it yet. best of luck on ur grow

our local shop has tons of that. Let me know how it goes.

Will do NoMo.

I bought 2 large bales of Sunshine Mix #4 today. They were HEAVY. They come wet, while ProMix comes completely dry (and very dusty - use a mask with it or you'll breathe a bunch of dust while working with it).

Based upon a lot of research I've done the past week, I've decided to add 20% perlite per gallon, and 2 tbs dolomite lime per gallon.

I'm transplanting tomorrow.

yes and yes if you want.

they're very similar.. but if i have a choice, it's always promix.. just seems blended better (plus i go for the hp with myco and lime already. sunshine is just peat and perlite)
sunshine is big chunky perlite, but seems not as much.

sunshine used to be the go-to here.. but now it's promix.
*don't get me wrong it'll work. but if there's an option; pro mix ;)

I liked Promix BX. Worked nice for me.

I've been using promix for the last year of growing........ I add lime to it........ I've had no ph problems........ works well for me.

I used it for a couple years now, perilite is a good idea for sure but not a must, dolomite lime is a good idea.

i added both usually, but sometimes skipped the perilite.

never got a wet bag, thats more to do withh how it is stored by the retailer. imo

Yea im not so sure they meant for it to be wet. Ive gotten wet stuff before,,but it was normally because it had rained on it somewhere during or after shipment.

I bought 2 bags of SSM#4 on Saturday. They were way heavier than the similar-sized bags of ProMix HP I've been buying. And I definitely detected a bit of moisture in the mix when I used it.

We'll see how it works. My guess is that it will serve as well as ProMix HP.

BTW, regarding SSM#4 and ProMix HP, I don't think I've ever heard anyone say (or post) that they liked one, but disliked the other.

I started out with Pro-mix HP+. Simply too costly for what i can make. $35 for a 3.5 CF bale is what i can get it for.

For $90 i can make 200 gallons of base mix. Fafard 3.5cf bale for $13, Super Compost $8/cf Black Kow Composted Manure $5/50lbs and dolomite lime is pennies on the dollar if you buy it in bulk. Ive bought it once for 3 Outdoor seasons.

Im all organic tho, not sure what direction you are going
