Question to co² experts
GrowYourFivestarted grow question 2 years ago
Grower friends! Question for co2 experts! I have an idea about yesterday's question .. My light is 1700 ppfd, co2 - 1200, but the nutrient solution was filled in 1100, as the manufacturer indicates, but I realized that this is not enough, now I'm trying to water 1400ppm +

I believe you are overfeeding honestly. If I run off is + 500 or so.. you could have build up in the medium.
Frankly 1700 umols is a LOT even with supplemental co2.
I wouldn’t go up to 1400 ppm.
Make sure your pH is where it should be. I run a point or two below 6 in Veg with coco/perlite.
I personally know a lot of commercial growers running similar set ups with co2 and none of them ever go above 1300 or 1400 umols/m2/sec.. especially in Veg. Those numbers are reserved for week 3-4 flower and that’s it. I can find you some charts for PPM/UMols/CO2 from commercial growers if you are interested DM me.

Hello community! I broke 2 branches this week. The first one happened by accident when I was draining the runoff, and the other when I was bending it.And today I came across a video where the author explains that silica can cause brittleness of branches. Does anyone have experience with silica and have you experienced anything like this? I add potassium silicate with each watering, at a concentration of 15ppm

How much do you feed them extra-PK with Biotabs ?I use Biotabs : Mycotrex, Bactrex, Orgatrex, Startrex with a light mix soil and light water (0.08 to 0.1 ec). Some people told me I shouldn't put much PK 5-8 because they easily burn. How much and how often would you feed them PK ? I use blumats with plain water in 6.5L pots, thx

FOAM in the DWC tankHi guys, yesterday I changed the solution in DWC and today I saw some foam in the tank.
I had some ph oscillation and used first ph down and after some silica to raise ph. I guess that could cause that foam, what do you think? Some tips?
