Hi Doc
I’m a new grower I’m using simple 4' fluorescents right now to get my plants going, but i want to get a better light to finish veg. and flowering stages. I ont want to spend a whole lot of money. My grow room closet is small 3 1/2' by 4 1/2'with just 2 plants for now. Can you tell me what kind of light cpf/hps or mh and what watt would Be best for over all growth and flowering for the best price.
Hi, I too started out with the 4’ shop lights, they work but you will see a world of difference if you move up to a 250 watt HPS. (I think the single best light to use is an HPS) If you have a tall closet, you could use a 400 W hps, or if you are willing to vent the heat out of the closet.
You can always try a Tri-Band LED from HTGSupply.com too. If you only want to grow two plants, a 90 W UFO LED will be fine, you can use a 120W or 300W if you want to grow more plants.
If you do go with the HPS, I”d still start the plants under your fluorescent lights for 2-3 weeks, then switch to the HPS. You will notice that most plants tend to stretch (grow tall with long space between nodes) when they are placed under an HPS (this is due to the excess of red and yellow light). So you should also get some ties to tie down your plants. Simply bend over the tops a bit (careful not to break off the top) this will keep your plants from growing too tall with long internodes, and will have promote bushy growth.
Good Growing,
