That Mh Bulb seems to be doing a good job in there. Whats with the mess in there? Get cleaning boii. The auto's are really picking up, I love the variations in different pheno's you have , short and stucky as fuck and one more stretched. You'll get a better yield of the taller thats for sure, but being an auto, don't expect too much lol. I got auto's same age as your's, they turn 4 weeks tommorrow, northern and critical HOG, shortest is 19inches tall lol, however I did cheat and use a mix of sun and hps to achieve that height and the northern is well into budding now, critical about a week behind.
Your setup looks great, tell me more about your ventilation and how you expect to move all that heat out of that cab running so many watts in the upcoming summer? Are you using air cooled hoods? Size of intake/extraction, I do not care about how many oscillating or clip fans you have, just the cfm rating and size of your intake/extraction for each tent.
Oh, also, what inspired the name Mainey??? Are you from Maine and moved to the UK?
Lol, see ya.
