A simple way to increase the magnification of your telephoto lens is to use a teleconverter (which weâll often abbreviate as TC). These are compact optical devices that attach to your lens (between the lens and the camera) and magnify the resulting image by a factor of either 1.4 Ã, 1.7 Ã, 2 Ã, or even (in rare cases) 3 Ã.
Ideal Ph Levels for Growing Cannabis. When growing cannabis in soil the Ph should usually be around the 6.5 â 7.0 mark. When growing in pots, a single Ph reading for each pot is advised. When growing outdoors it is best to take two or three Ph measurements from different areas of the grow area.he Ph level of your soil will ascertain how well your cannabis plants are able to take up the nutrients. If the Ph level is out of the correct range, the growth rate of the plants can stall or even stop.
As you may know CFL light can be as efficient in growing marijuana plants as HPS bulbs but you need a lot of them but that can be a very helpful thing because you can place them around the grow room and around your plants to maximize the light usage.rom these ratios you can see that the most efficient CFL bulbs are at the start of the range from 12 W to 45 W but 13 W bulbs are too weak and you would need a lot of them to grow cannabis so the best CFL lightbulb for growing marijuana is the 42 W one because it is the most efficient and will grow the biggest plants.
