I have a sativa strain propable girl It is 2 weeks in flowering. 50cm height and 70 length with topping. I have it in a 10lt tank but i would change it with a 20-25 lt tank. I must leave my home for 15 days. Did all the water of 20-25lt evaporate or drinked from the plant? sorry for my bad English.
Hi Dadas!! If you have to leave it for 15 days, it's a risk! Your plants will use more water than nutes... so in time water will leave, but nutes will stay in your reservoir. This will change PH, and PPM, drastically.. I would set up an auto-top-off bucket full of fresh water. Do you know how to do this? Put one of these in your reservoir: [ame=http://www.amazon.com/AWI-Float-Valve/dp/B000X92KH4]Amazon.com: Float Valve: Pet Supplies[/ame] Then put a bucket up high, with a tube going into the float valve. Fill the bucket with water, then pray before you leave on your trip. Your typed English, and grammar is better than a lot of people's here! =)
