How long can I keep my plants in those red plastic beer cups?

Hey all im new to growing and have a couple questions. #1 how long can I keave my plants in those red plastic beer cups? how big should I let them get before putting them in the ground? right now theyre in a homemade greenhouse to protect them. the two biggest ones are barneys blue cheese, they are growing the fastest and i dont want to get them rootbound...thanks for any tips

I take 2 cups, I drill holes in the bottom of one and then put it in another, so I can dump out the drainage. When I start seeing roots come out of the holes in the bottom of the first cup then I transplant.

Seen plenty of people finish in those very same cups. You can get about an oz dry off one plant using 12/12 from seed & those cups.

I'd say you have around 3-6 months and they'd be severely root bound. Depends on your plant and light cycles a lot.

They'll be lightly root bound around 2 months, give or take a month. Definitely good for a month, at least.

how old are thy?about 2 week?i would be transplanting thm now,but not outdoors.

no there doing fine i do the same thing all the time just put holes in the bottom f the cups atleast 4 holes for the water to run off. and let them get about a half a foot or till you start seeing roots come out some then press on the sides of the cup to push the dirt nd roots to gether around the hole cup then gently grab the stem at the soil and pull up some and if the dirt will come with it then you pressed right if not do it agian and agian till you see the dirt come up with the roots. then just put the plant in dirted area where you will be growing it and ta da easy and not messy and you dont have to cut the cup or do much to transplant.

A well developed root ball is much easier to transplant successfully with far less stress to the plant.

yea like i said till you see roots. which for mine was around 6-7 inches. then it took me 3 minutes and no stress at all to my big plant. shes only 3 weeks and if 2 feet tall.

thanks guys, so what I should do is wait until i see roots coming out the bottom or the cup and then transplant, another question....when do I start fertilizing my plants and what is a good veg fertilizer and a good flowering fertilizer....also will I get more bud if I put them in the ground as apposed to putting them in bigger contaniers in a homemade greenhouse? im growing barneys farm blue cheese (2) greenhouse seeds "the church" (2) these two strians are supposed to be pretty tough to mess up and are resistaint to mold....also have 4 big buhhda seeds auto white widow going..will they get bigger if I put them in the ground apposed to bigger containers? o I forgot about I got 1 g13 white widow and g13 purple lady...all the seeds were fem seeds....any info will help...thanks

Age Old Organics grow & bloom w/ super bat Budswel for fat juicy colas. Fox farms ocean forest. Upon transplanting only feed plain water for the first three weeks to use up nutrients in soil. Then start feeding w/ liquid nutrients keeping the nutrient content to a minimum gradually increasing the strength of solution as plants continue to grow. Use nutrients every 2 waterings or so to not burn plants. Also a very mild seaweed foliar spray applied once a week will aid in the uptake of nutrients. Mycorrizhae beneficial bacteria can also be used. Available in liquid or granular form and can be purchased at your local garden center. Not a nutrient bacteria for your root enviroment causes a root explosion massive roots equal masive plants. This recipe is easy to maintain and cheap. Will out yield most hydro setups and competitive nutes for a fraction of the price. GOOD LUCK.

thanks tyrannabudz for the info....what do you guys think? when I transplant them do I go directly in ground or in some kind of containers?

Im only worried cause every once in a while here is storms like god is pissing on us.

?mmmmm????
