2 gallon pots with no drainage?

Is drainage necessary or can I just use the right amount of water?
Should I put an inch or two of gravel or something at the bottom?

Oh, and what is the right amount of water to give a plant in a 2 gallon pot?
And then how often should I go about doing that? once or twice a week?
Help me out here. Thanks

Why would you have a pot with no drainage holes? Do you own a drill? Not trying to be a dick.. but you should be doing some more reading before you get anything into pots... Ur results will be as good as your research ..

agreed. drainage is a must...your plants will not be pretty if you are lacking in that dept.

Your nuts, drainage is imperative. 2 gallon pots are also pretty small

get 3gallon Smart Pots... im using 5 gallon but it seems u prefer small lol... also fill ur nute water, distilled water etc into water bottles cut a medium hole in the cap and evenly water the plant.... they are 16oz use 1 and a half bottles

i use 3 gallon smart spots ( Canna CoCo) and add Drip clean it negates any salt biuld up or nuit lock out from salt biuld up

I WATER EVERY DAY TILL DRAINAGE ANG NEVER FLUSH
