Feeding outdoor plants

I’m growing outdoors in 3 gallon pots with organic soil mix I just went simple since it’s my first grow ever. They’re still seedlings right now, but what do you guys feed your outdoor plants? I want to stay away from anything harmful. I will probably have too many questions. I jumped ahead in the growers bible to harvesting and am completely overwhelmed lol. I will create that topic at a later date. Appreciate you all!


Osmocote. Dirt cheap, available everywhere, feeds for months. Probably the best and easiest option.

A more complete fertilizer than almost anything else for outdoor, much better than anything else at the garden center.

I use the same nutrient solution whether I grow indoors or outdoors, if I’m growing in containers. I normally grow outdoors in the ground, but I’ve done both over the years.

Do a little research on nutrients and stay away from anything that is more than a two-part system to keep it simple for you until you get a little experience under your belt.

You will have a lot of questions, ask them and you’ll get answers. The only dumb question is the one you didn’t ask!

The Growers Bible you have has a shitload of useful information in it from cover to cover… you’re going to have to read it to understand it. Roll yourself a nice joint, find a comfortable spot, open it up to section that interests you and start reading about how to grow cannabis.


I’ve gotten through the first 1/4-1/3. Appreciate you thank you!


I will look into this thank you!


Reading makes me sleepy… unless it’s about plants.


I’m an outdoor grower. In containers I use organic soil, wait 3 weeks before first feed as there is enough in the soil. I feed mine water soluble kelp and organic fish fertilizers


In smaller pots 5 gallons or smaller I dump the contents and re amend it’s called ROLS ( recycled organic living soil … kelp, crab, alfalfa , EWC and compost I haven’t really gotten in Dolomite Lime but will try at some point I like teas never had issues with burnt plants or even seedling for that fact my recent addition had been the all purpose we talked about earlier. I don’t mix / till any raised beds the worms do that for me.


Good luck @Fluffhead420
I try to keep things simple for my outdoor , SST ( seed sprouted tea ) and compost Teas composted seaweed , Fish Hydroslate , Composted Manure – chicken manure must be well composted as fresh will burn them big time . I have used Dynamic Lifter - pelleted chicken manure in the past it’s good for slow release . blood n bone ,Epsom salts …probably doesn’t sound very simple now I read back over this lol . As mentioned above my friend , read all you can and ask lots of questions ,I strongly believe some of the best people to ask are on this site . My next adventure is into no till soil


If you are wanting to stay organic I would skip the osmocote, and use fish fertilizer. All depending on the additives. In the original soil make a tea full of beneficial organisms and use that.

The only problem with the fish fertilizers outdoors is every critter in the country will dig at it. I try to use mostly plant based feed after my plants are in. Manure will also work…i love rabbit and sheep for top dressing. Worm castings worked into to top inch of soil is one of the best things you can use.
I feed mine a shot of Megacrop when I get a chance. I am not a fan of time release fertilizers. Just never had any good results with them

That is true. I stick to living soil I’ve mixed and give it earthworm tea in my yard. The living soil still had alot of the fishy smell from the crab meal, but I keep it fenced off from my yard critters. They keep pretty much everything else out (my dogs and cats).

Here’s what I use from start to finish . !/8 tsp per gal for starts every watering after planting and well established two tbl spoons per plant every second watering . I mix in a five gal bucket flood the plant and pour in the mix 400 - 150 gal bags been doing this for years you can use more just watch your plants for nutrient burn on leaf tips . Just back off if you notice tips burning . SEA-GROW 16-16-16
