Container question first grow... Help

I have a two gallon container my box is from dealzer cash crop 4.0. Now I have 4 pk's two are doing great and the roots are huge I was wondering will they stop growing or is it enough for the plants to continue growing ? Or should I get a bigger container ?

I think you meant a 10 gallon container? I can't tell if there are 3 or 4 plants in the container but either way they need to be split up. They look like they are positioned too close together which probably isn't an issue right now but when they start flowering you will have trouble getting light everywhere. I would separate them sooner rather than later because those roots are going to get so twisted that you wont be able to get the plants apart without cutting some roots off. I grow in 5 gallon buckets and I once had a plant who started to pack the bucket pretty good. The only drawback I experienced letting it do this was that the amount my rez held was diminished enough that I had to keep a close eye on it (especially towards the end of flower when she was drinking a lot).

Ok thanks. And no it's a little bucket only two gallons if that. I have another bucket but won't fit. I'm gonna move them into their own five gallons in a rdwc setup I think jus gotta find how much light.

Have the 4.0 extra this is 4th wk end of first wk of bloom. No problems other than choice of plnts.
These were gift sooooo!!! Using their nutrients and following their schedule for 8 - 9 wk grw.
Next time going to cut back to 2, as this is only good for 2 max IMO. Going to build my own now that I have a templet only larger for my LED lights 16" sq. Also changed to more air stones (full length of container), & a different air pump, because theirs made so much noise, now I can't hear anything.
