why pots without holes? Will only kill plants. I have tried most every pot from 1-5 gallons. The best product I've used is the .20 cent baggie pots you can get at a hydro shop in 1-5 gallons. They have holes premade in em. Reusable... The 2 reasons I really like em is because you can pack your plants together and when full of water weight a lot and easy to tell when they are light/in need of watering. Use masking tape for strain and flower date with sharpe. super investement for close to nothing. I have also compared clones in size pots 1, 2, 3 and 5 gallon pots. My experience is the 2 gallon is best overall with no real difference in final product. Bigger 3/5 gallons take more space so less plants can be grown. Comparing root balls I am not seeing much difference 2,3 and 5 gallons. Remember, this is a 9 to 11 week plant to finish. The rootball doesn't have enough time to grow out of the 2 gallon pot in most every pot I've seen. Now this is a nature product so I have seen the occasional clone that turned for some odd reason into super clone or midget clone. Not wasting my time with anything other then 2 gals. now with a couple 3 gallons when vegged a long, long time...my of research....
