TDM Values??
MrGreenManstarted grow question 5y ago
Hello everyone!
Done a bit of research into ppm and just got a meter and I just wanted to ask everyoneβs opinion for autos what the best values to aim for would be for different stages of growth? Found General Hydroponics feed chart and Iβm currently keeping to that.

Hey I also use the GHE chart and I have found it works great. I do go a little above the chart as I add purpinator to my water/nutes starting week 5 of growth at 2ml and then all the way up to 20ml(4L) for week 11.
Happy growing

I generally use for coco 200ppm to start and I bring that up depending on how the plant reacts I use 600ppm as a max normally some may need a bit more

VPD values!! How much off the recommended ranges is not good anymore??My first time monitoring vpd values on a grow. Day time vpd value : 1.5-1.6. Night time vpd value: 1.2-1.4. I think recommended value for mid to late flower is 1-1.3. I hit it at night but during the day temps going up makes my life difficult. How much off range is not good?Week 5
