fluorescent tubes

New fitting are about twice the maximum cost of second hand unit. Only one double fitting can grow many plants until they about 2 weeks old. As they grow taller the light is too dim at the sides and bottom of plant, more tubes will be needed to light these parts of the plant. The light from fluoro's needs to be very close to the foliage about 10cm. max., heat may cause burning or curling of the leaves if there touching the tube. If there are 6 large plants they will need 10 or 12 of 36 watt fluorescent tubes for my cannabis seeds.

cannabis on rockwool

The pH of the nutrient solution should be checked regularly with a pH meter. pH too high: lower it with Nitric acid (during the growth period) Phosphoric acid (during the flowering period) pH too low: increase it with an alkaline solution (during the whole period) Take care with these acids because they are corrosive for your big bud feminized. The pH of a nutrient solution for growing your "favourite plant" should be between 5 and 7. Because rockwool is made from rock and rocks can be very alkaline, rockwool can also be very alkaline itself. This results in an immediate rise of the pH value of the nutrient solution as soon as it comes in contact with the rockwool.

THC: when is it ready?

What happens if you leave them too long?If we didn’t pick at that point, we would go past peak, the mushroom head would explode, and at the end of the process, we would have too high a percentage of overripe glands. The THC would have converted itself into other cannabinoids, such as CBN and cannabidiol (CBD). Trichomes basically just shrink and evaporate. All your terpinoids evaporate, and your drug evaporates also (cannabis seeds). Sometimes they just fall off. So you don’t want to go past peak, and you don’t want to go early.

Growroom tricks

Advantages of Dry Ice Dry ice is inexpensive and easily obtained.Dry ice is non-toxic, but the extreme cold can damage tissue. Wear insulated gloves when moving unwrapped chunks. (Pants of some sort are also a good idea around large exposed chunks of dry ice.)Dry ice requires no flame, electricity, or moving parts to use. Dry ice is compact and more easily moved than tanks of CO2 gas. Dry ice does not put any heat or water into the atmosphere. The frozen CO2 actually helps to control heat due to the fact that of dry ice remains frozen below 100 degrees below zero (terrible for the cannabis seeds)! Disadvantages of Dry Ice The continuous generation of CO2 gas limits the use of exhaust fan cycles.

usefull tests for cannabis

Using the CO2 Test Kit 1. Place the short piece of flexible plastic tubing on the end of the plastic syringe. 2. Carefully snap off each end of the glass tube. 3. Push the plunger on the syringe all the way in to clear any air. 4. Draw back the plunger to the 100 cc mark in the air to be tested. 5. Place the glass tube in the open end of the flexible tubing. 6. Push firmly on the plastic plunger and slowly force the air through the glass tube. The entire process should take about one minutekeep your cannabis seeds safely away. 7. Notice the white powder in the tube change color (either red or blue depending on the brand).8. When all the air in the syringe has been forced through the glass tube, the CO2 level is indicated by the top of the colored band in the indicator tube.

When to Flower

When to Flower. Indoors, growers force marijuana to flower at any time. Even seedlings will indicate sex and produce flowers given the right conditions. Marijuana flowers in response to the light cycle. Under natural conditions, the plant senses oncoming autumn by chemically measuring the uninterrupted dark period. Indoors, when the light regimen includes a dark period of 10-12 hours each day, the plant stops its vegetative growth cycle and starts growing reproductive organs, male and female flowers, which usually occur on separate plants. When light hits a leaf the tissue absorbs certain rays which it uses in photosynthesis. Those rays are unavailable to leaves below the top. 1000 watt HID lights penetrate only 12-18 inches of leaves depending on their size and quantity all from marijuana seeds.

The easiest and most effective method gardeners use to eliminate odors is using a negative ion generator. These units are sometimes called ion fountains or air ionizers. Negative ion generators charge air molecules with extra electrons, giving them a negative charge. When negatively charged air ions comes in contact with a positively charged dust particle, the air molecule gives up its electron. The positively charged particle is neutralized and no longer floats since it is not as influenced by electrical charges. The particle drops from the air (precipitates) and falls onto the wall or floor. It no longer creates an odor out of your marijuana seeds that now are plants.
