Why LEDs?

I don't use climate control, so temps vary. Right now (mid-winter), I'm recording temps of 10-25C. In summer, that will be around 15-20C minimum, and up to 35-40C maximum. ECs average 2.2. I run heavier to begin with (up to EC2.4) and tail off during the grow as salts build up in the coco. Though drain-to-waste does self-flush, salts still tend to build up in coco, especially inside the pot, and near the top, where there is a lot of evaporation. I use a hybrid organic/mineral salt nutrient (Canadian Xpress, also known as CX Nutrients), and a silica additive. I never used to use Cal-Mag under HPS, but I do under LED. There's less transpiration under LED, so the plants seem to like higher ECs to compensate.

Ok thanks for the info!!

I am running pure perlite in air pots so the medium dries out as fast as possible, then I water as soon as I feel they arent fully saturated with water. I find the lower the water holding capacity of the medium, the more often you can water which leads to faster growth.


I just finished my new setup, have never grown with my latest setup, I will speak to you again in two months, maybe I can get massive cola's like yours, if I dont, then I will the next run!:)

Im running 1.8EC now, but I think ill push it to 2.0. I make my own nutrients. I dont include Silica right now, but I do have it and I will start using it.


Peace out!

You fucking people don’t even know how to cultivate. This site is for Cops. This is a BS form. Non of you people seem to know shit, on this post or any other post. MFers asking about rooting and shit. Basic 101 shit. Read a book.
