Grow Questions1100 or 1500 PPM Co2

1100 or 1500 PPM Co2

Overgrothostarted grow question 4 years ago

Do I keep this 1,100 PPM - 1,500 PPM level for the rest of flower (of course stop 2 weeks before harvest) and is it worthwhile to bump up to 1,500 PPM?

1500 is about the highest you can go. Test your EC in your feed and the runoff. If the runoff is lower, you can increase feed. If it's higher, then you are overfeeding and need to cut back. This is all based on the assumption that your temps and pH are good.

expert opinion asked ? Maturity in day 49 flower from 60-65 (according to breeder)Maturity in day 49 flower from 60-65 (according to breeder) I'm not sure about the degree of ripeness. I used Co2 for a few weeks (1000ppm), the grower says ~60-70 days of flowering, so I would be missing 10-20 days, but they look quite ripe ? What should I do Thank you

Feeding right after repotting (coco coir).After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200. I guess EC gets diluted (biggest part of coco coir is new). Should I increase EC of the feeding water? I see slower growth but it may as well be due to stress of repotting.

Questions about watering I created a 40 ml solution, the instructions say to transplant after the sprout has grown to the top of the plastic cover and the roots are visible through the plug. The question is, is 40 ml of liquid enough for this growth? I think not.
