I am wondering how you grow those dense buds. i have gone soil and half way thru my flowering hydro, and i looks like i am not getting those dense tight flowers i am looking for. Is there some nutrient i am missing or something. i am running t5 veg. 400 watt hps flower 4x4x6 tent. exhaust pulling thru hood by a 6 " can fan 24/7 2x4 tray filled with hydroton with a recirculating drip system feeding 4 times a day. i add fresh water every other day and add one gallon of full strength nutrients mid week and change rez every week. USING BLOOM EURO A&B FOR BASE. SUPPLEMENTS-BLOOM ROOTS-LIQUID KARMA-BLOOM CAL/MAG FOR VEG. AND BLOOM EURO A&B BASE. SUPPLEMENT-BLOOM ROOTS FOR FIRST 4 WEEKS- BOTANICARE SWEET RAW-BOTANICARE HYDROPLE FOR FLOWERING. STILL NO DENSE NUGS. CAN SOMEONE PLEASE TELL ME WHAT I NEED FOR SUCCESS.
I am not too familiar with HPS, but I have been growing for going on 20 years. I may be wrong, because non-dense buds can be caused by many things, including strain, lack of nutes,
too much nutes, or lack of light. Based on your info, a 400 watt HPS in a 4 X 4 tent seems like it may be too small. You're only looking at 3437.5 lumens per square foot. Not enough
for flowering,
if you're looking for 100% efficiency. Ideally, 1000 watt HPS lights would go into a square meter tent, which is 3.25 X 3.25, and 13006 lumens per square foot. You will
(strain dependant) get the dense buds you are looking for. And maximum yields that your strain(s) will allow. I'd put a 1000 watt light in there, or limit your light to an area of 25" X 25",
getting you within a few lumens of 13006 lumens per square foot that a 1000 would do in the square meter, and you'll still get the same yield, and the denser buds (strain dependent).
I hope this helps.
