HERE ARE MY BLUEBERRY LOWRYDER 1 WEEK FROM SEED UNDER A 600 HPS 4FT AWAY TEMP IS 27C AND HUMIDITY IS 45% CAN YOUS TELL ME IF THERE LOOKING NICE AND HEALTHY PLEASE
You'll save yourself some good electricity money going with Flouros at that young and tender age. No need for the 600W yet unless it is all you have. If it is, consider making a nursery for clones and seedlings that uses flouros.
They are looking good start giveing them a little feed now it will bring them on if you are gonna flower that lot under 1 600 opt for the s.o.g method.................tyke.................
DONT feed after only one week. You have to wait until they are 2 to 3 weeks old, and then start ur nutes at half strength. Best of luck with ur grow, they look very nice so far!
