Leafy Light Buds in DWC

[rickyanny]

When harvesting plants out of my DWC I always end up with leafy light buds. Some buds are better than others but overall the outcome is a letdown after what is expected. The environment does get too hot, GH 3 part solution was used, and the strain was sage n sour. What could be the main cause of this? Please feel free to ask more questions because I would love to learn how to get better.

Also a 400 watt hps in about a 2 x 3 area was used with just white walls.

Try some Koolbloom ,

To much heat will cause that to happen.

will co2 injection help the heat problem?

[alwayssleepdeprived]

if I remember right co2 does allow for higher temps but if it's gettin over 100 in there I'd agree you should start there and work once that's resolved

also depending on the type of strain a 400w hps won't grow huge like show buds especially if it's not extremely close to the plants 400 loses power quickly as you move it away that was definately a problem of mine on the first grow

a pic always helps give us some of the info if ya know temp and light distance maybe ph and ppm foods plant height how long in 12/12 etc

Watch out for c02 in a people living area. It is heavier than air and can flood out oxygen and kill. Just a heads up. Be carefull around people.

A 400 hps will do pretty good but mine would grow right into the light and burn the top off. I got a good yield just burned tops. That was a small drip system not DWC, 3 foot is as high as I could get for the light to do well.

Yer getting too hot- bring the temps down. You want to flower @ like 75'F to keep things tight.

CO2 will allow the plants to remain healthy at higher temps, but it won't tighten flower structure. There are a few PGRs that will, but that's not your issue.

Is it good to have a small fan on the light while flowering? Would 600 watt make a big difference?

A 600 will make your problem worse unless you fix the ventilation system.

You need to move air into the op from outside the op airmass and dump the warmed, moist air someplace where it can not be easily re-drawn into the grow.

Your ventilation system, whether an exhaust fan with a passive intake (2x the size of the exhaust duct) or an exhaust fan with a powered intake (a fan about the same size as the exhaust), should be able to move the room's airmass in 3-5 mins. In example, a 1000 cu ft room needs a 200-330cfm exhaust blower. Your mileage may vary depending upon how much light power you're running.

It's been said- got to get the air down to 75-77, 80 on a bad day. Even CO2 rooms only run at 85, 90 intermittent max.

'Good ventilation' does not include leaving a closet door open a couple hours a day.
