grow media for seedlings ?

I been using jiffy , then transplant in a couple of weeks to final grow pot in fox farm ocean .

I use ocean forest mixed with 25% perlite or a similar mix.

Never had as strong and fast growing plants in a nutrient free mix. Have to be very careful not to overwater the young roots is all. Drainage is key.

yeah I like to keep around 1/4 perlite to soil . Do you start your seeds right off in the ocean forrest mix ?

Yes. I thought that was the point to the thread. 😉

I prefer miraclegro seedling soil over jiffy. Happy Frog with mycorrhizae works too but i think the frog is happy about the free fungus gnats i got. Imo pot size and watering are more important to start healthy seedlings.

I just had some miracle gro soil that I used. Wasn’t specifically for seedlings but doesn’t hold as much moisture as I thought it would which is good.

it is , just wasn’t sure if the little seedlings could handle starting off in nutrient based soil with perlite . got some pricey beans I’m gonna start , and I don’t want to mess it up .

There are some soils that are hotter. But as long as you don’t add any additional nutrients to it you’ll be fine , fox farm bag soils are strong! I’m growing in an organic potting mix seedling through flower and everything seems to be fine

Then start them in a light seedling mix. Its an easy decision. I tried it before. It works. And it wont hurt them.

I didnt know mg seed starter had fertilizer added. I wonder if it is as strong as ocean forest or the like just not organic?

Happen to know the starting ec?

2 to 1 perlite / vermiculite mix in 2 inch square pots in tray with 1/4 inch of water;

self-watering so no chance to overwater, also easy to start seeds this way too, use a heating mat for best results, good luck!

Tried the MG several years ago. Way too expensive. I use a standard potting mix, currently Kellogg patio plus sifted through a kids sand/beach toy.

I add about 25% composted horse manure and a tablespoon of Epson salt to a 5 gal bucket and works like a charm at a fraction of the price.

MG seedling soil is .03 .03 .03, its mainly sphagnum and perlite. At half a solo cup per seed i never considered the cost.

MIMedGrower

What do you suggest ? They don’t grow very fast in just the jiffy media .

Thats why i use ocean forest and perlite.

People usually use. Ocean forest with added perlite. Or coco coir mycorrhizae with some added things people make there own mixes and such. Maybe try the ocean forest

I didn’t have any luck till I actually microwaved a damp peat mix then put about 3” of that sterile on top the intended soil mix in coupla big solo cups . & wet with distilled water. Never took that ”sterile” is important for starting serious before . Seein is believing . i’m a believer now . Guess if you don’t have the damp off plague of my luck , might not be necessary. I also think i lost some to too hot a soil mix for ”starting” . My theory is once the root gets past the 1st 3” at the top of the cup, your germination is golden . Once they looked good I put’m in my amended soil. My 1st success at birthin babies .

Can You Grow Cannabis with Miracle-Gro Soil or Nutrients?

Miracle-Gro Slow Release Soil is Not Suited to Growing Marijuana!

Many of us have grown up seeing Miracle-Gro being used in our homes, so we know that it works for ‘regular houseplants’. Cannabis is just a tough weed, so Miracle-Gro should be great for it, right?

The biggest problem with the standard Miracle-Gro nutrient formula is that it’s one formula for the entirety of the plant’s life cycle. Even if the standard Miracle-Gro plant food is decent for the first stage of your plant’s growth, it won’t be good for the budding/flowering phase. The ratio of nutrients your plants need changes drastically between seedling and full flower. Marijuana grows best with a nutrient system that accommodates their changing nutrient needs.

Avoid Miracle-Gro Soil for Growing Weed!

Do not use “Miracle-Gro” soil or any soil that has “extended release” nutrients for growing cannabis. These types of soil will continue to release nitrogen to your plant roots for up to 6 months. This can cause deficiencies or burn your cannabis plants in the flowering/budding stage, reducing your overall yields. I have seen growers successively grow cannabis in Miracle Gro, but many of them struggled with nutrient problems in the flowering stage (like the following) even though plants were healthy throughout the vegetative stage.

What’s worse than the standard Miracle-Gro nutrients is the original Miracle-Gro soil. Standard Miracle-Gro soil has “time-released” nutrients which contain high levels of nitrogen. While this formula will work okay in the cannabis vegetative stage (the first stage of life), the nutrients will continue to be slowly released throughout the plant’s life including during the cannabis flowering stage, which is not good.

Standard Miracle Gro nutrients contain too much nitrogen and not enough of other nutrients for your cannabis flowering stage, and as a result of the time-released nutrients, you will notice that your leaves in the flowering stage will get nutrient burn and your buds just won’t grow as big as they could. Learn what you can do to make sure buds grow as big as possible!

Important: Do not use “Miracle Gro” soil or any soil that has “extended release” nutrients. These types of soil will continue to release nitrogen to your plant roots for up to 6 months. This can burn your cannabis plants in the flowering/budding stage and reduce your overall yields.

There’s nothing inherently wrong with Miracle-Gro nutrients, and if you’re willing to learn about nutrients, you can use the various different formulas and get a cannabis plant to grow. For example if you’re using regular soil, you could use the standard Miracle-Gro formula for vegetative, and their “bloom” version for the cannabis flowering stage.

Yet there are so many nutrient systems that are specifically formulated to grow a plant like cannabis. Why not choose to get better cannabis nutrients that will almost always produce better results? Some options like Dyna-Gro are priced about the same as Miracle-Gro nutrients, but you will consistently get bigger yields and more flavorful buds.

Miracle gro seed starter mix

So I bought a bag of miracle gro seed starter mix. It’s just peat moss, so I thought. I germinated 2 seed, paper towel method. when they sprouted a tap root, I put them into solo cups with a 50/50 mix of perlite and seed starter mix. Both of the seeds made it to the top of the soil then stopped before the husks came off. And they just stayed there. So, being the curious person that I am, I gently pulled the seedlings out of the medium. They came right up. No resistance at all! When I looked at the tap roots, the ends were curled up and did not look happy. Now I was really curious, so I looked at the bag of starter peat moss, and low and behold, the stuff is enriched with miracle gro food. So this just leads me to believe that the SEED starter “mix” is too hot for the seedlings. WTF. has anyone else had any experience with this stuff? I have 2 more seeds germinating now and they will be going into a 50/50 coco/perlite mix this time. I already have 2 in there that just started veg. About 3 weeks old and started the training on them last night. These two were started in used/depleted soil, basically inert soil. so there was no way they were going to burn. Now they are in miracle gro cactus, palm, citrus mix at about 70/30 soil/perlite and happy as heck! The food that is in this mix isnt the “feeds for 6 months” stuff. Just enriched with the nutients outa the bag. And the ratio is 0.6-0.2-0.4 so half of that is 0.3-0.1-0.2 which is found to be the optimum ratio for cannabis (3-1-2 or so I have read)

so far under 4 x 32.5w cfl 2700k 2600lm each and 1 x 23w (I think) 5000k just for spectrum diversity and 20/4 light schedule. I have 4 more 32.5w bulbs for flower.
