I have seen posts where the size of buds from LED'S is questioned and while I do not want to get involved with that argument I want to post some pics of what I have experienced in my current grow.
These are photos of a medium bud on one plant there are much larger with photos to come the soda can is a 12oz that had to be tilted so you can see it behind the bud
This is the largest top flower from a different plant the same strain from a top vendor, same pack just a different seed in the same tent, nutes are the same light is the same pot size is the same
So who's fault is it when our grows are not as large as what we expect ?
Seed vendors - they show us what we want to grow not necessarily what we get
Light Vendors - each is the best just ask them
Nutrient manufactures - it will turn a Daisy into a Redwood really it will
The Grower - If 7ml is good than 10ml is better, test equipment is not important, It's a weed stick it in the ground and harvest a Kg, Nutes? MG works on my tomatoes beside those others are too expensive, Let's alter the growth cycle, pull off all the leaves, tie it down, break branches then wonder why it is growing slow.
Bottom line is GENETICS and phenotype are the most important and that can be different from seed to seed then it's up to us to provide the proper environment, nutrients, water and control anything else that pops up
These were grown under both Mars 2 and Reflector series lights
