Thank you for this! It was so simple and easy to follow.

[@AtlantaTerry]

At 1:56 you say to wrap the clear bottle with foil to prevent algae growth. This is true. However, all you need to do is use a green plastic bottle. The green will do the same job as the foil. Or you can combine both tips: green plastic + foil. Terry Thomas Brookhaven Gardens Atlanta, Georgia USA

Terry Thomas Can I use 7up bicarbonate drink bottle as green bottle?

[@02121978able]

Thanks for🙏🇮🇳, this trick🙏☺

What seeds did you use

[@Science.Buddies]

From the materials list in the written instructions (linked in the video description): "Start with a green leafy plant like spinach or lettuce, or herbs like oregano or basil. "

Can you do this with smaller plastic bottles?

[@Science.Buddies]

You can try it with smaller bottles, but depending on the type of plant there might not be enough room for the roots.

Where did you get the thick cotton strips?

[@FBPrepping]

Any old rag works, Amanda. Sure, if it is porous or cotton-like works better, but there is a physic effect that will take the water to the roots, it's called capilarity. It makes water flow upwards.

Which plant is this?

[@Science.Buddies]

The project instructions recommend a "green leafy plant like spinach or lettuce, or herbs like oregano or basil."

So can any body help me I want to ask what would be the hypothesis of growing this.....

[@JimmyBHarvests]

There is research suggesting water bottles very commonly leach chemicals when water is left in them for long periods of time or in hot environments (like a grow room.) I’ve created a video outlining these concerns and suggesting other free alternatives to use as reservoirs: kzbin.info/www/bejne/eGOTkp-upal7o6s Please help spread this message to the growing community so we are not ingesting unnecessary chemicals!
