Safe to switch to supersoil?

Just wondering if the hivemind thought it would be a good or bad idea to take plants that have grown in FFOF up til now (around 50 days in veg) and transplant them into supersoil for their final pots in a couple/few weeks.

Had a ton of issues over the past month with the FFOF and pH but I think I am finally on the other side of that and growth is really taking off now. I wish I had known about supersoil before I got going. Definitely next grow. But do you think it would be okay to transplant them into a super mix for their next and final leg through the summer/fall?

I dont want to shock the system, though I cant imagine it would be a bad move for them considering the issues ive had in FFOF.

just a bit of extra info:
I have been keeping the plants on 18/6 by moving them in at night until the temps get a little higher overnight here in the PNW per @MattyBear advice. Currently I have preflowers showing on 6 of them, all female.

heres my support ticket so you have an idea of the particulars.
Strain; Type, Bag seed, ** 10 plants - Seed - Egmont Outdoor (70/30 sat dom)**

Soil in pots, Hydroponic, or Coco? FFOF/Perlite (60/40) in 5gal pots

PH of runoff or solution in reservoir? 6.3-6.8

What is strength of nutrient mix? 1200ish (FF trio)

Indoor or Outdoor: Outdoor

Temps; Day, Night: day: 65F- 85F @ 35-70%hum / night: 40-60ish @ 60%hum

@garrigan62 @AAA @Skydiver - I dont know who the supersoilers are here so tag em if you got em

You can use Kind Soil when you pot up to larger containers. Are they in 5 gallon now? If so what size will you be using. You’ll want 1LB Kind Soil per gallon pot size…all directions are on their web site. Check them out…and if you have questions shout out.
Just don’t put transplant directly on top of Kind soil
Use some FFOF as a buffer layer


I don’t really have any feedback on the super soil. But if you decide to go that route, just transplant before you’re expecting the plants to start transitioning to flower.

@Skydiver - yep, in 5gal pots right now. Considering potting up to 10gal - if I do that, kind soil is on the radar now. thanks! gonna have a read about it. problem may be that we have chloramine treated water here, so I’d have to figure out neutralization (via acidification or chemical additive) or filtration (cost prohibitive) - or another source. Course, I could always let it evaporate off - but that takes a couple months :slight_smile:

@dbrn32 - yessir. I suspect this will happen around mid to late june, if i do it. these 5 gal pots are going to be filled up soon I believe, so it could be good timing to put them in their forever home and transition to outdoor only.

this would be the 3rd transplant, which i expect is frowned upon by some. the first 2 transplants, though, went off without a hitch. I dont want to stress them anymore than i already have with all the pH nonsense - so i am on the fence with potting up at all.

Here I am. I do super soil and make my own. If you do decide to transplant make sure that your soil is for flower only and you should be fine.

If you are in fabric pots you can cut the pot away and probably avoid any shock when potting up.

I transplanted from 3 gallon happy frog/ocean forest mix to direct supersoil mix into 10 gallon fabric pots with no buffer layer and no issues, in fact they took off.

Based on the size of my plants, if I had more room I should have potted up to 15 gallon. It all depends on how big you want to let your plants get.

I don’t PH. I just use this on my garden hose for watering and tea brewing:

Here are the plants I’m speaking of:


Nice looking plants!

I would go larger than #10, personally. They are a long way from being finished outdoors and are going to be MONSTERS.

If it were me (and it’s not), I would use #45 smarties filled with re-usable soil (lots of options here… but is sure minimizes the cost of purchasing new soil every.single.grow.)

Best of luck!

#45 are pretty much stationary at that weight. I’m scared to pick up these #10 pots after water as it feels like the handles will rip off.

But as a general rule, if you want big plants use big pots.

i did tear the handles off a #20 a week or so ago. Such fun.

Ouch. I’m trying to control the size of these but as mentioned they still got a long way to go!

I’ll probably prune them back to 4 major colas and use the rest for clones.

My indoor plants go from rooter tray to solo cup, then to 1 gallon, and sometimes 3 gallon depending on what I’m doing. As long as you’re not stunting them in flower shouldn’t be a big deal.

Well AAA first things first. Do your transplant first. and as stated above the best way would to cut the bags and slide them into there new home and make sure you water the hole your putting them into first then place them in and water again and you’ll be fine. Wait a couple of weeks before doing any pruning. a couple of weeks should be long enough for them to get over any shock… And you should be ood to go my friend…


H2o2 a good idea for post transplant right? At what ratio?

I never heard of that.

Another @garrigan62 tip I picked up along the way for root health. Unless I’m mistaken

@AAA - side question - whered you get those canvas colored smartpots?
(i ended up painting my 5gal pots white and theres a definite difference. not gonna go so far as to credit the paint for my plants perking up, but in conjunction with all the other adjustments, im certain it helped - thanks!)

cheers. figured those were the ones but wanted to be sure.

@garrigan62, can you clarify this a bit? do you mean to leave out components (such as blood meal) to make it a soil for flower only?

1/2 Recipe
4 large bags of a high-quality organic potting soil with coco fiber and mycorrhizae (i.e., your base soil)
12.5 to 25 lbs of organic worm castings

2.5lbs blood meal
1.5lbs rock phosphate
3/8 cup or 6 tablespoons Epsom Salts
