Starting Inside - Finishing Outside

Hi Folks!

We plan to do an outdoor grow with about 2000 plants. Normally i would put them in 5 or 7 gal pots but I don’t have space in the greenhouse…I plan to veg them in 1 gal pots for 4 or 5 more weeks at which point they will most likely be root bound… I don’t think this will be a problem as long as I water them frequently with the drip system. What do you think ? Will they be OK after I replant them in large pots?

Thanks in advance for your feedback!

They should be fine - still young enough that they won’t suffer irreparable damage. When you transplant them out just gently massage the root ball apart a bit to stimulate the roots to break out - and then hit with with a fish emulsion or tea to stimulate growth.

I have also found that square pots are preferable to the round, with the round pots the roots will circle and create more of a ball, whereas when the roots hit a 90 degree corner they seem to generally go down into the pot rather than balling up as much.

I think your plants will be fine if they don’t get up potted. If you do find that they are terribly rootbound just be sure and break up the roots quite a bit with you transplant them outside and really saturate the soil after you plant them. If they get too crowded while you are waiting to transplant them, I would defol a little bit in order to create better airflow thru the plants and ultimately encourage new growth.

Starting inside is the best way to start a healthy crop. Every year I start seeding in side inter t5 lights, Before I throw them outside. But the long term stay in a small pot is a little bit of a bummer. But like you said watering often will help keep them in good shape. Be sure to inoculate the soil for transplant and everything will be ok. Next year pick a cloth pot or a root making pot to keep from being as root bound. Best of luck and happy growing.

Also the defoliate idea is definitely good. Just remember that some/most strains will stretch if trimmed at the bottom.

Thanks for the advice… It was my opinion as well but I have a couple of friends that were suggesting that the plants would be “shocked” and “stunted” Which just doesn’t make sense to me. especially if I continue to water in the same manor once they are outside.

I’ve helped do this on a smaller scale, and yes slightly root bound. But , we placed them directly in the ground after veg , and they thrived! Sunlight is the best! A little shocked at first but within a week or so they took off.

If they are going from inside, or a greenhouse to outside - it can help if you harden them off for a week before hand. Put them outside for a few hours a day - increasing the time as you go. This will allow them to toughen up to the more intense environment of outdoors (sun, wind etc) and reduces transplant shock.

Just curious, what soil are you using?
