at the moment im just using CFLs, im in the process of building a grow tent and getting BETTER lights. i found this light that is switchable between MH and HPS. It says its 600w, but i could use a 400w MH with this ballist right? like i said im a newbie to the extreme, just trying to learn the most i can
Some ballasts will let yu use different wattage bulbs and switch between MH and HPS. I have digital ballasts that have several wattage settings and will automatically switch for MH and HPS.:hubba: Look closely at yer ballast and see if there is a wattage setting (mine has a switch on the side that has 600, 400, and 250). If yu
don't have that switch then yu can
only use the 600w bulbs.
But that is not a problem, yu can still use 600wMH, yu just have to wait till the kids are a bit bigger and keep it 2-3feet above the plants.
As they grow and reach for the light yu can bring it down to within 12-18inches (if yu have very good air movement).
for right now just get some more High lumen CFLs. Lowes has some that are really potent and will cary yu until yu get yer HIDs. Look for the bulbs that have 6400-7000K on them not the soft white(3000-5000K), as the soft white is more for flower than veg.
The reason everyone is bustin yu on the soil is because MJ is very nutrient sensitive. The soil yer in now could make them grow like madness or it could kill them b4 the end of the week. Yu should never use 20-20-20 (especially on seedling to young growth) unless yu are a very experienced grower. Right now they should be in unfertilized soil, but it is up to yu if yu want to change at this point.
Right now yu are starting out way behind the 8-ball here and we don't want to see yu fail and give up b4 yer started good.
So many people want to jump in head first and end up crashin-n-burnin because they don't realize just how envolved this hobby really is. It's sooo much more than puttin a few seeds in the dirt and watering them. The most important thing now? Read all yu can. I have 3 books on growing and have been here for a while and still feel like a noob some days. We are glad to help yu B successful
and will help yu as much as we can. There's a lot to learn but yu will in time and practice. Green mojo to ya
