I haven’t tested that yet! I will be dialing that in on my next run with Romulan, Chem D and DJ Shorts Instablue. When I started my Clones were already well rooted and in vegged under my t5 fixture

Ok cool, I am doing Chem D x Purple Punch. I’m running the 4800 at 18" & about 40% power right now to get my photone reading at just about 200ppfd.
Wish Mars Hydro had a handy ppfd guide with power x distance conversion & suggested seedling/veg/flower settings.

TODAY IS THE DAY!!! I’m so excited!!! It’s FLIP DAY!! Both my Mars Hydro FC4800 lit tent AND my 4000w HPS room will be lights out at 7pm. Lights set from 7 - 7 I will not do a 2 or 3 day dark period. Just set it and forget it (ill be checking like 500 times a day) I gave all the plants their first transition feeding, then as soon adds this 50gal drum of feed is consumed we will start right into flower feeding!

They are loving that LED tent. What a beauty of lush uniform growth. If I didn’t already own an HLG Blackbird with UVA 30. I would be looking at the FC-4800

@Jinglepot just came across your grow journal, very nice you work your plants very well i like how uniform you keep your room and these are all from seed correct?
Couple questions do you use co2 in hps and led room? what day and night temps do you maintain? also is this organic i will get a proper read through the journal as im sure this has been mentioned.
Thanks

Hey there! Thanks for your interest! These are clones, I net train them for a few weeks to let the bottom bramches catch up. I lollypop the lower half completely. I keep my Temps around 25-27c during day and 22-24c at night. During the last 3 weeks I’ll let the night Temps get down to 10-15c to bring out colours and trichome production. I dont use co2 at all. I basically grow with a mix match program ive put together over the years that works for me. It’s not organic. High Output Grow 3 part with General Hydroponics floralicious plus, diamond nectar, flora blend, Flora Nectar and liquid koolbloom. Along woth advanced nutrients b52 and Cannas Rhyzotonic and intermittent peroxide and silica feedings.
In a nutshell, lol

Thank you for the update. 
Plants are looking great.
I think in that case, MH stood for Mars Hydro. I had to read it twice myself

Ive been dealing with record setting cold and ot hasent been going well. If you follow any of my other threads you’ll know this already. That being said, my Mars Hydro grow has been the LEAST affected by the cold. The one still got a little sad, but all in all they are decent shape. They badly need a pruning underneath, but I’m going to wait a few days. The weather has warmed up, ill let them perk up a bit.
My maim grow room woth 2 heaters going full suffered as well. 5 of the 10 plants are not looking well.
